24V Lithium Batteries

Why Epoch Makes Some of the Best 24V Lithium Batteries

A 24V lithium battery should do more than replace two old lead-acid batteries. It should deliver steady power under load, provide enough capacity for the way you actually use your equipment, protect itself in demanding conditions and work intelligently with the rest of your electrical system.

Epoch Batteries offers a complete range of native 24V LiFePO4 batteries for trolling motors, RVs, camper vans, boats, solar systems, mobile work platforms and off-grid installations.

The lineup includes compact 60Ah power for weight-conscious applications, a versatile 100Ah marine battery, high-output 230Ah Essential Series storage and premium V2 and V2-T Elite batteries for advanced RV, marine, Victron and inverter systems.

What makes Epoch different is the ability to choose the right level of technology for the installation.

Depending on the model, available Epoch 24V lithium battery features include:

• Native 24V LiFePO4 construction
• Bluetooth state-of-charge monitoring
• Internal cold-weather heating
• Advanced Battery Management System protection
• IP67 waterproof and dustproof enclosures
• High continuous and short-duration current output
• Native Victron CAN-bus communication
• DVCC-managed charging
• UL 1973 pack certification on select models
• Integrated Class T fuse protection on the V2-T platform
• Series and parallel expansion
• Warranty coverage of up to 11 years
• U.S.-based customer and technical support

Instead of forcing every customer into one generic battery, Epoch allows you to select the capacity, output, environmental protection, communication features and safety architecture that match your system.

Why Choose Epoch Instead of a Generic 24V Lithium Battery?

Many 24V lithium batteries appear similar in a product photo. They may have the same nominal voltage, similar case dimensions and an impressive-looking amp-hour rating.

The important differences are usually found deeper in the specifications.

A premium 24V lithium battery should answer all of these questions:

• How much stored energy does it provide?
• How much current can it deliver continuously?
• Can it handle short-duration surge loads?
• Does it protect itself against low-temperature charging?
• Does it include internal heating?
• Can you monitor state of charge directly?
• Is the enclosure appropriate for marine or exterior use?
• Can it communicate with an inverter and charging system?
• Does it include pack-level safety certification?
• Is primary battery-level fault protection included?
• Can the battery bank be expanded safely?
• Is technical support available after the purchase?

Epoch publishes the specifications needed to make those decisions and offers several models with distinctly different strengths.

That is an important advantage over purchasing an unknown battery based only on price and amp-hours.

The Native 24V Advantage: One Battery Instead of Two 12V Batteries

A traditional 24V battery bank is often created by connecting two 12V batteries in series.

That arrangement adds another battery case, a series jumper cable and multiple terminals that must remain clean, protected and properly torqued. If the two batteries age differently or begin a charging cycle at different states of charge, each internal BMS may respond independently.

A native Epoch 24V lithium battery places the complete 24V pack inside one managed battery platform.

Fewer Batteries and Connections

One native 24V battery can eliminate:

• A second battery case
• The inter-battery series jumper
• Two additional high-current terminals
• A second independent BMS
• Separate Bluetooth readings
• Additional hold-down hardware
• Another potential corrosion or resistance point

Fewer connections can make the installation cleaner and easier to inspect.

One Unified Battery Management System

A native 24V battery uses one integrated BMS to monitor the complete pack.

The BMS can evaluate cell voltage, battery current, temperature and protection conditions across the full 24V platform rather than relying on two batteries that independently protect themselves.

Simpler State-of-Charge Monitoring

With two Bluetooth-equipped 12V batteries in series, the operator may need to compare two battery readings.

A native 24V Epoch battery provides one state-of-charge value for the complete battery.

More Efficient Use of Installation Space

One battery may free valuable space in:

• A trolling-motor battery compartment
• An RV electrical bay
• A camper van cabinet
• A boat machinery space
• A solar equipment enclosure
• A mobile workshop

The exact space savings depend on the batteries being replaced and the dimensions of the Epoch model selected.

Meaningful Weight Savings

Replacing two large lead-acid batteries with one lithium battery can remove substantial weight from a boat, RV or mobile system.

That can improve:

• Boat balance and draft
• Trailer payload
• RV cargo capacity
• Vehicle efficiency
• Installation access
• Available storage space

Compare usable watt-hours as well as battery weight when planning the conversion.

Which Epoch 24V Lithium Battery Should You Choose?

Epoch’s current 24V collection serves several different types of customers.

24V 60Ah Pro Series: Compact Premium Power

The Epoch 24V 60Ah Pro Series battery is designed for customers who want a compact, lightweight native-voltage battery without giving up premium monitoring and environmental features.

It provides approximately 1.54kWh of stored energy and is well suited to:

• 24V trolling motors
• Bass boats
• Bay boats
• Pontoons
• Compact RV systems
• Mobile power equipment
• Small off-grid systems
• Backup power
• Technical installations where space and weight matter

Its Group 27 footprint and approximately 30-pound weight make it an attractive alternative to two heavy 12V lead-acid batteries.

Available features include:

• 80A continuous output

24V 100Ah: The Versatile All-Around Choice

The Epoch 24V 100Ah lithium battery stores approximately 2.56kWh.

It provides a practical balance of capacity, weight, output and physical size for customers who need more runtime than the 60Ah battery without moving to a Group 8D-size 230Ah system.

Common applications include:

• All-day recreational trolling
• Bass and bay boats
• Pontoons
• RV house power
• Camper vans
• Small inverter systems
• Marine electronics

• Mobile work equipment

Its available features include:

• 120A continuous output
• Bluetooth monitoring
• Internal heating
• IP67 waterproof and dustproof protection
• Smart BMS protection
• Series and parallel support
• Expansion up to a 400Ah 24V bank
• 11-year manufacturer warranty

For many boaters, the 100Ah model is the best starting point when they want meaningful all-day capacity without the weight and space requirements of a 230Ah battery.

24V 230Ah Essential Series: Maximum Output and Capacity at a Strong Value

The Epoch 24V 230Ah Essential Series battery stores approximately 5.89kWh in one native 24V battery.

It is designed for customers who want substantial energy and high sustained output without requiring the full communication and certification architecture of an Elite system.

Its published capabilities include:

• 230Ah capacity
• Approximately 5.89kWh of stored energy
• 200A continuous output
• 300A short-duration output
• Bluetooth monitoring
• Internal heating
• Advanced BMS protection
• Group 8D footprint
• IP54 enclosure protection
• 11-year manufacturer warranty

The 200A continuous rating makes the Essential Series especially attractive for high-demand systems where sustained current matters.

Common applications include:

• Tournament trolling-motor systems
• RV inverter systems
• Camper vans
• Marine house banks
• Off-grid cabins
• Mobile workshops
• Solar energy storage
• Long-duration backup power

The IP54 enclosure should be installed in a protected compartment rather than an area subject to standing water or temporary immersion.

Choose the 230Ah Essential Series when capacity, high sustained output and value are the primary goals.

24V 230Ah V2 Elite: Premium System Integration

The Epoch 24V 230Ah V2 Elite stores the same approximately 5.89kWh of energy while adding features designed for professional and fully integrated electrical systems.

Available V2 Elite capabilities include:

• Native Victron CAN-bus communication
• DVCC-controlled charging
• Bluetooth monitoring
• Internal heating
• IP67 waterproof and dustproof construction
• Advanced BMS protection
• High short-duration surge capability
• UL 1973 pack certification
• Remote battery controls
• External battery gauge
• Large parallel-bank support
• 11-year manufacturer warranty

The V2 Elite is particularly persuasive for premium RV, marine and off-grid systems using compatible Victron equipment.

Instead of forcing the Victron system to estimate battery condition from terminal voltage, the battery BMS can communicate data and operating limits to a compatible GX device.

That creates a more coordinated energy system with centralized monitoring and battery-directed charging.

Choose the V2 Elite when system intelligence, Victron integration, environmental protection and scalable storage matter more than selecting the highest possible continuous-current rating.

24V 230Ah V2-T Elite: Premium Power with Class T Protection Built In

The V2-T Elite is Epoch’s most complete 24V battery platform for safety-conscious professional installations.

It combines approximately 5.89kWh of energy with:

• A user-serviceable 300A Eaton Class T fuse
• UL 1973 pack certification
• Native Victron CAN-bus communication
• DVCC support
• Bluetooth monitoring
• Internal heating
• IP67 enclosure protection
• Remote digital battery gauge
• External battery controls
• Advanced BMS protection
• Series and parallel expansion
• 11-year manufacturer warranty

The integrated Class T fuse places high-interrupt hardware protection directly at the battery.

That can reduce external installation clutter, shorten the unprotected conductor path and eliminate the need to find mounting space for a separate large Class T fuse block immediately outside the battery.

The V2-T does not eliminate the need for a main disconnect, properly protected downstream conductors, branch fuses, busbars or correct system engineering.

It does give premium RV and marine installers a more complete battery-level protection platform from the start.

Why Epoch Premium 24V Lithium Batteries Are Built Around Safety

No responsible battery manufacturer should claim that one feature makes a battery absolutely safe in every application.

Battery safety comes from several layers working together.

Epoch’s premium 24V batteries combine model-specific layers such as:

• Stable LiFePO4 chemistry
• Cell monitoring and balancing
• Advanced BMS protection
• Temperature monitoring
• Low-temperature charge protection
• Internal heating
• IP-rated enclosures
• Pack-level certification
• Integrated fault protection
• Correct charging parameters
• Communication with compatible system components

LiFePO4 Chemistry

Epoch 24V batteries use lithium iron phosphate, or LiFePO4, chemistry.

LiFePO4 is widely chosen for deep-cycle marine, RV and solar applications because it combines stable chemistry, consistent voltage and long cycle life.

Chemistry alone does not make an installation safe. The BMS, charger, cables, fuses, disconnects, mounting and environmental protection must also be appropriate.

Advanced Battery Management System Protection

The integrated BMS monitors the battery and provides model-specific protection against conditions such as:

• Overcharging
• Excessive discharge
• Overcurrent
• Short circuits
• High cell voltage
• Low cell voltage
• High charging temperature
• Low charging temperature
• High discharging temperature
• Low discharging temperature

A BMS is an important internal protection layer, but it is not a substitute for correctly sized external circuit protection.

Why UL 1973 Pack Certification Matters

Select Epoch 24V batteries publish UL 1973 pack certification.

This is different from simply stating that a battery contains UL-certified cells.

A pack-level certification applies to the assembled battery platform, including the relevant protection, electrical and mechanical considerations covered by the standard.

That distinction can be important for:

• Premium RV installations
• Marine house banks
• Commercial mobile systems
• Off-grid energy storage
• Professional installers
• OEM builders
• Customers who want third-party product evaluation

UL certification does not make the entire installation compliant with every electrical, marine or vehicle standard.

The complete system still depends on appropriate mounting, conductors, protection, charging equipment, disconnects and commissioning.

Why the Built-In Class T Fuse Matters

Large lithium battery banks can deliver very high current into a short circuit.

A Class T fuse is commonly selected for large inverter and lithium installations because it provides fast operation and high interrupt capability.

The Epoch 24V V2-T integrates a user-serviceable 300A Eaton Class T fuse inside the battery enclosure.

This provides several practical benefits:

• The fuse is located close to the energy source.
• The length of external unfused cable can be reduced.
• A separate external Class T fuse holder may not be required at the battery.
• High-current wiring can be cleaner.
• Valuable installation space can be saved.
• The approved fuse can be serviced without replacing the complete battery.

The internal fuse does not protect every downstream circuit.

The inverter, charger, DC distribution panel and individual branch conductors may still require separate fuses or breakers based on their cables and equipment ratings.

IP67 Protection on Select Models

Select Epoch 24V batteries use an IP67 enclosure.

An IP67 enclosure is dust-tight and designed to withstand temporary water immersion under the conditions of the rating.

This is valuable in:

• Boat battery compartments
• RV exterior bays
• Overland vehicles
• Mobile work systems
• Damp off-grid enclosures
• Installations exposed to spray, dust or weather

IP67 does not mean the battery should be installed permanently underwater or left in standing water.

Terminals, cables, busbars, chargers and communication connections must also be protected appropriately.

Internal Heating and Low-Temperature Protection

LiFePO4 cells should not be charged below their approved minimum temperature without an appropriate heating strategy.

Select Epoch 24V batteries include internal heating controlled by the BMS.

When charging energy becomes available and the cells are too cold, that incoming power can be used to warm the battery before normal charging begins.

This is useful for:

• Winter RV travel
• Ski-area camping
• Cold-weather boating
• Early- and late-season fishing
• Northern solar systems
• Unheated battery compartments
• Overland and expedition vehicles

Internal heating is different from low-temperature cutoff.

Low-temperature cutoff stops the battery from accepting a damaging charge. Internal heating can prepare the cells so charging may resume after they reach a safe temperature.

Native Victron CAN Bus and DVCC Control

Selected Epoch Pro, V2 and V2-T batteries communicate with compatible Victron GX equipment through CAN bus.

The battery BMS can provide information such as:

• State of charge
• Battery voltage
• Current
• Temperature
• Alarm status
• Permitted charge current
• Permitted discharge current
• Charging-voltage limits

With DVCC enabled and configured correctly, compatible Victron charging equipment can respond to the limits communicated by the battery.

This can coordinate:

• Inverter/chargers
• MPPT solar charge controllers
• Compatible DC-to-DC charging
• Shore-power charging
• Generator charging
• System monitoring

For premium RV and marine systems, this closed-loop communication is one of the strongest reasons to choose an Epoch Elite battery.

What Size 24V Lithium Battery Do I Need for My Trolling Motor?

Choosing a 24V trolling motor battery requires three separate checks.

1. Confirm that the motor requires 24 volts.
2. Confirm that the battery can provide the motor’s maximum current.
3. Choose enough amp-hour capacity for the desired runtime.

Voltage determines whether the battery and motor are compatible.

The continuous-current rating determines whether the battery can safely support the motor.

Amp-hour capacity determines how long the motor can run.

A battery can have enough stored energy for a long fishing day but still be unsuitable if its continuous-current rating is below the motor’s maximum draw.

Confirm the Motor Voltage

Use a native 24V battery only with equipment designed for a 24V electrical system.

Never connect a 24V lithium battery to a trolling motor designed only for 12V operation.

Some brushless trolling motors can operate on more than one voltage. Follow the motor manufacturer’s installation and battery requirements.

Check Maximum Current Draw

Find the trolling motor’s published maximum current draw.

Choose a battery with a continuous-discharge rating that meets or exceeds that requirement.

The circuit breaker, cable, connector and disconnect must also support the motor current.

Do not use a battery’s short-duration peak rating as its normal continuous rating.

Calculate Capacity from Average Current

Trolling-motor runtime can be estimated with this formula:

Runtime in hours = usable amp-hours ÷ average current

For conservative planning, preserve approximately 10% reserve:

Planning runtime = battery amp-hours × 0.90 ÷ average current

The most important value is average current, not maximum current.

A trolling motor may draw substantial current at maximum thrust but spend most of a fishing day:

• Making small GPS-anchor corrections
• Operating at low or moderate speed
• Following a shoreline
• Remaining stowed while the outboard is running
• Turning off while the angler reties or lands a fish
• Drifting with wind or current

A boat operating continuously at high thrust in strong wind will use energy much faster than a boat making occasional position adjustments on calm water.

How Much Capacity Is Needed for an All-Day Trolling Motor Battery?

“All day” should be defined before selecting a battery.

For one angler, an all-day trip may be eight hours. For a tournament angler, it may mean 10 to 15 hours from launch through weigh-in.

The following estimates preserve a 10% battery reserve.

Capacity Needed for a 10-Hour Day

• A 5A average draw requires approximately 56Ah.
• A 10A average draw requires approximately 111Ah.
• A 15A average draw requires approximately 167Ah.
• A 20A average draw requires approximately 222Ah.
• A 30A average draw requires approximately 333Ah.
• A 40A average draw requires approximately 444Ah.

Capacity Needed for a 12-Hour Day

• A 5A average draw requires approximately 67Ah.
• A 10A average draw requires approximately 133Ah.
• A 15A average draw requires approximately 200Ah.
• A 20A average draw requires approximately 267Ah.
• A 30A average draw requires approximately 400Ah.
• A 40A average draw requires approximately 533Ah.

These estimates demonstrate why there is no single universal all-day trolling motor battery.

A compact 60Ah battery may provide all-day operation for a light boat with intermittent low-speed use. A heavy boat holding position in strong wind may require 230Ah, 400Ah or more.

How Long Will an Epoch 24V 60Ah Battery Run a Trolling Motor?

Using a 10% planning reserve, a 60Ah battery provides approximately 54Ah for runtime calculations.

Estimated runtime would be:

• At a 5A average draw: approximately 10.8 hours
• At a 10A average draw: approximately 5.4 hours
• At a 15A average draw: approximately 3.6 hours
• At a 20A average draw: approximately 2.7 hours
• At a 40A average draw: approximately 1.35 hours

For a 10-hour day, average current would need to remain near 5.4A or less.

For a 12-hour day, average current would need to remain near 4.5A or less.

The 60Ah Pro is best suited to:

• Weight-conscious boats
• Moderate fishing days
• Intermittent trolling
• Efficient brushless motors
• Anglers who frequently use the outboard between locations
• Customers who prioritize compact size over maximum reserve

How Long Will an Epoch 24V 100Ah Battery Run a Trolling Motor?

Using a 10% reserve, a 100Ah battery provides approximately 90Ah for planning.

Estimated runtime would be:

• At a 5A average draw: approximately 18 hours
• At a 10A average draw: approximately 9 hours
• At a 15A average draw: approximately 6 hours
• At a 20A average draw: approximately 4.5 hours
• At a 30A average draw: approximately 3 hours
• At a 40A average draw: approximately 2.25 hours

For a 10-hour fishing day, average current would need to remain near 9A or less.

For a 12-hour day, average current would need to remain near 7.5A or less.

The 100Ah Epoch battery is a strong all-around choice for:

• Bass boats
• Bay boats
• Pontoons
• Moderate wind and current
• Recreational all-day fishing
• Anglers who want more reserve than a compact 60Ah battery

How Long Will an Epoch 24V 230Ah Battery Run a Trolling Motor?

Using a 10% reserve, a 230Ah battery provides approximately 207Ah for planning.

Estimated runtime would be:

• At a 10A average draw: approximately 20.7 hours
• At a 15A average draw: approximately 13.8 hours
• At a 20A average draw: approximately 10.4 hours
• At a 25A average draw: approximately 8.3 hours
• At a 30A average draw: approximately 6.9 hours
• At a 40A average draw: approximately 5.2 hours

For a 10-hour day, average draw can remain near 20.7A.

For a 12-hour day, average draw can remain near 17.25A.

That makes a 230Ah battery a persuasive choice for:

• Tournament anglers
• Long fishing days
• Heavy boats
• Extensive GPS anchoring
• Strong wind and current
• High-thrust trolling motors
• Anglers who prefer to return with substantial reserve
• Boats operating far from charging

Actual runtime will vary with motor efficiency, thrust setting, propeller condition, vegetation, hull resistance, boat weight, wind, current and temperature.

Which Epoch Battery Is Best for an All-Day Trolling Motor?

Choose 60Ah When:

• Weight and compact size are the priorities.
• The motor is used intermittently.
• Average current is low.
• Fishing conditions are generally moderate.
• The boat frequently moves between locations using the outboard.
• You do not need a large tournament reserve.

Choose 100Ah When:

• You want a practical all-around trolling motor battery.
• Fishing days commonly last six to ten hours.
• GPS anchoring is used regularly but not continuously at high output.
• The boat encounters moderate wind or current.
• You want additional reserve without installing a large Group 8D battery.

Choose 230Ah When:

• Tournament-day runtime matters.
• Fishing days may last 10 to 15 hours.
• The boat is heavy or carries substantial gear.
• GPS anchoring is used for extended periods.
• Wind and current can create high sustained demand.
• You prefer to size around difficult conditions instead of a calm-day estimate.
• The battery may also support compatible marine house or inverter loads.

Choose 400Ah or More When:

• The motor may average 30A or more through a 12-hour day.
• The boat operates in consistently difficult wind or current.
• The system must support both trolling and substantial auxiliary loads.
• Long-distance or commercial operation requires exceptional reserve.
• Charging opportunities are limited.
• The installation is being designed as a premium high-capacity energy system.

Epoch 400Ah-Plus 24V Lithium Battery Banks

Epoch’s current individual 24V batteries reach 230Ah, but approved parallel configurations allow customers to build 400Ah, 460Ah and substantially larger 24V systems.

This distinction matters.

A 24V 400Ah lithium battery bank can be built from four matched Epoch 24V 100Ah batteries connected in parallel.

A 24V 460Ah lithium battery bank can be built from two matched Epoch 24V 230Ah batteries connected in parallel.

24V 400Ah Bank

Four 24V 100Ah batteries provide:

• 400Ah at 24V
• Approximately 10.24kWh of nominal stored energy
• Substantial trolling-motor runtime
• Parallel redundancy
• Multiple IP67 battery enclosures
• Bluetooth monitoring
• Internal heating
• Strong continuous-current capability

With a 10% planning reserve, a 400Ah bank can support approximately:

• 36 hours at a 10A average draw
• 24 hours at a 15A average draw
• 18 hours at a 20A average draw
• 12 hours at a 30A average draw
• 9 hours at a 40A average draw

24V 460Ah Bank

Two 24V 230Ah batteries provide:

• 460Ah at 24V
• Approximately 11.78kWh of nominal stored energy
• Fewer battery cases than a four-battery bank
• Exceptional RV or marine house capacity
• Significant inverter runtime
• A simpler high-capacity installation

With a 10% reserve, a 460Ah bank can support approximately:

• 41.4 hours at a 10A average draw
• 27.6 hours at a 15A average draw
• 20.7 hours at a 20A average draw
• 13.8 hours at a 30A average draw
• 10.4 hours at a 40A average draw

These calculations describe battery runtime at the stated average DC current. They do not account for recharge energy arriving from solar, alternators or shore power while the system is operating.

Why Epoch 400Ah-Plus Banks Are Ideal for Premium RV Systems

A 400Ah-plus 24V battery bank can provide more than 10kWh of stored energy.

That is enough capacity to support a serious RV or expedition-vehicle electrical system when the inverter, charging sources and DC distribution are properly engineered.

Potential loads include:

• Refrigeration
• Lighting
• Water pumps
• Ventilation
• Communications
• Computers
• Induction cooking
• Microwaves
• Coffee makers
• Power tools
• Entertainment equipment
• Air-conditioning support
• Mobile-office equipment

A 24V architecture can be particularly attractive for 2,000W- to 3,000W-class inverter systems.

At the same wattage, a 24V system carries approximately half the DC current of a 12V system.

Before inverter losses, a 3,000W load requires approximately:

• 234A at 12.8V
• 117A at 25.6V

Reducing current can help limit voltage drop, cable heating and conductor-size requirements when the complete installation is engineered correctly.

A 24V RV system will usually need a properly sized 24V-to-12V converter for traditional 12V lighting, pumps, fans, control boards and other DC equipment.

Why Epoch 400Ah-Plus Banks Are Ideal for Premium Marine Systems

Large boats and yachts may operate substantial electrical loads away from shore power.

A high-capacity 24V Epoch battery bank can support:

• Refrigerators and freezers
• Navigation equipment
• Radar
• Autopilots
• Communications
• Lighting
• Pumps
• Watermakers
• Marine audio
• Computers
• Inverter-powered galley equipment
• Electric cooking
• Air-conditioning support
• Workshop equipment
• Large trolling or auxiliary motors

A 24V architecture is common in larger vessels because it can reduce current compared with an equivalent 12V system.

Premium Epoch V2 and V2-T batteries add features particularly valuable in marine systems:

• IP67 protection
• Native Victron communications
• DVCC-managed charging
• Centralized monitoring
• Internal heating
• High-capacity parallel expansion
• Pack-level safety certification
• Integrated Class T protection on the V2-T

The complete marine system must still include appropriate battery restraints, cable protection, disconnects, busbars, branch fusing, grounding, labeling and environmental protection.

How to Build a 24V Parallel Battery Bank Correctly

Parallel wiring increases amp-hour capacity while keeping system voltage at 24V.

Only combine batteries when the exact model supports parallel operation.

Use:

• Identical battery models
• Matching capacities
• Batteries of similar age
• Similar states of charge before connection
• Equal-length battery cables
• Properly sized common busbars
• Battery-level protection where required
• A correctly rated main disconnect
• Appropriate branch protection
• Charging equipment sized for the complete bank
• Communication settings specified by Epoch

Do not combine different Epoch product families merely because they share the same voltage and amp-hour rating.

A 400Ah- or 460Ah-class lithium bank stores a large amount of energy and should be designed and commissioned by an experienced installer.
