24V Lithium Batteries

Maximize Efficiency with Premium 24V Lithium Batteries

The traditional way to build a 24-volt power system is to wire two heavy 12V lead-acid batteries in series. That arrangement occupies two battery locations, adds a series jumper and creates more terminals that must remain clean and tight. In many marine and mobile installations, the finished bank can weigh well over 100 pounds before trays, hold-downs and cabling are included.

Epoch 24V lithium batteries place native 24-volt LiFePO4 power inside one managed battery platform. A single 24V lithium battery can simplify the installation, reduce weight and deliver more consistent deep-cycle voltage when its energy, current output, physical dimensions and charging requirements match the system. The integrated Battery Management System monitors the cells together instead of relying on two separate 12V batteries and two independent BMS units.

Current Epoch options include compact 60Ah power for trolling motors and mobile systems, a 100Ah battery for extended runtime, and high-capacity 230Ah Essential and Elite models for large RV, marine, inverter and off-grid applications. Cycle-life ratings currently range from 3,500+ to 6,000+ cycles by model, and every battery shown in the collection carries an 11-year manufacturer warranty.

The Single-Battery Advantage: Ditching Dual 12V Systems

When comparing two 12V batteries vs. one 24V battery, the native-voltage option offers several practical advantages:

• More usable installation space: One case can free a second tray location in a boat's rigging compartment, an RV battery bay or a camper van's under-bed electrical cabinet. The exact space saved depends on the replacement bank and the dimensions of the selected Epoch battery.
• No external series jumper: A native 24V battery connects to the 24V load through the main positive and negative terminals, eliminating the inter-battery series cable used between two 12V batteries. Fewer exposed connections can simplify inspection and reduce potential corrosion or resistance points.
• Substantial weight reduction: The Epoch 24V 60Ah Pro Series battery stores 1.54kWh and weighs approximately 30 pounds. The 24V 100Ah model stores 2.56kWh and weighs approximately 48.5 pounds. Compare stored and usable energy—not weight alone—when replacing a lead-acid bank.
• Unified cell monitoring: One internal BMS monitors the complete 24V pack for conditions such as excessive charge, discharge, current and temperature. Two 12V batteries in series each manage themselves independently and can drift apart in state of charge if they are mismatched, aged differently or charged unevenly.
• Simpler system visibility: Bluetooth-equipped Epoch batteries report the status of one native-voltage pack. This removes the need to compare two separate battery readings when diagnosing a series-bank issue.

24V LiFePO4 vs. Lead-Acid Voltage Discharge Curve

The representative graph below shows why a 24V LiFePO4 battery can deliver steadier performance through most of a discharge. A 25.6V-nominal LiFePO4 pack remains near its working voltage for much of the cycle, while a 24V lead-acid bank made from two 12V batteries declines more progressively as stored capacity is used.

Top Applications for 24-Volt Lithium Power

24V Lithium Trolling Motor Batteries

A 24V lithium trolling motor battery is commonly paired with compatible 70- to 90-pound-thrust motors on bass boats, bay boats, pontoons and other mid-sized rigs. The flatter LiFePO4 discharge curve helps the motor maintain steadier response while working structure, fighting wind and current or holding a GPS anchor position. Always confirm the motor's voltage, maximum current draw, breaker size, cable gauge and manufacturer battery guidance.

Epoch's 24V 60Ah Pro Series battery provides 1.54kWh of stored energy, 80A continuous output, Bluetooth monitoring, internal heating, IP67 protection and Victron-ready communications in a 30-pound Group 27 footprint. The 24V 100Ah battery increases stored energy to 2.56kWh and continuous output to 120A for compatible systems that need greater runtime or current capacity.

RV and Camper Van Electrical Systems

A 24V RV lithium battery can be an efficient foundation for a custom van, skoolie, expedition vehicle or larger RV electrical build. At the same wattage, doubling system voltage approximately halves DC current. A 3,000W load draws about 117A at 25.6V before conversion losses, compared with about 234A at 12.8V. Lower current can reduce voltage drop and may allow smaller conductors when cable length, insulation, temperature, fuse requirements and applicable standards are properly considered.

This architecture can suit 2,000W- to 3,000W-class inverters, but system voltage alone does not determine inverter capability. The selected battery's continuous BMS output, inverter surge, cabling, busbars, fuses and charging equipment must all support the load. Native 12V appliances also require a correctly sized 24V-to-12V converter.

Off-Grid Solar and Backup Power

A 24 volt solar battery is a practical choice for cabins, workshops, remote communications, mobile work trailers and backup systems. At the same controller output-current rating, a 24V battery platform can accept roughly twice the charging wattage of a 12V platform, subject to the controller's PV-input limits and the battery's maximum charge rate. Size the solar array, MPPT controller, battery bank, inverter and protection devices as one coordinated system.

Sizing Your 24V System: 60Ah, 100Ah and 230Ah

60Ah Compact Power—and What 24V 50Ah Shoppers Should Know

A theoretical 24V 50Ah lithium battery stores about 1.28kWh, the same nominal energy as a 12V 100Ah battery. Epoch's current compact option is 60Ah rather than 50Ah, providing 1.536kWh of stored energy. It is well suited to many weekend fishing, compact marine, mobile and small off-grid applications when its 80A continuous rating provides enough current and the expected runtime matches your use.

100Ah for Extended Trolling and General-Purpose Storage

A 24V 100Ah lithium battery stores approximately 2.56kWh—twice the energy of a 24V 50Ah pack and about 67% more than the current 60Ah model. It is a strong option for anglers facing longer days or heavier conditions and for RV or solar systems with larger daily energy budgets. Estimate runtime by dividing usable amp-hours by average load current, then reserve capacity for wind, current, cold weather, conversion losses and unexpected use.

230Ah for Large Inverters and Long Off-Grid Runtime

Epoch's 24V 230Ah batteries store 5.89kWh in a single case. The 230Ah Essential Series battery offers 200A continuous output, Bluetooth, heating and IP54 protection for protected RV, marine and off-grid compartments. The 230Ah V2 Elite Series battery adds IP67 construction, native Victron CANBus communication and a 500A 30-second peak rating, with 110A continuous output. Select the model by continuous and surge requirements, communications, enclosure rating and installation environment—not capacity alone.

Epoch Premium Engineering: Built to Outlast

• Smart Bluetooth monitoring: Current 24V models let users view information such as state of charge, voltage, current, temperature, cycle data and battery status from a compatible smartphone.
• Internal cold-weather heating: LiFePO4 cells should not be charged below freezing without an approved heating strategy. Heated Epoch models use incoming charging power to warm the cells before normal charging begins, supporting winter camping, cold boat storage and shoulder-season use. Operating limits vary by model.
• Advanced BMS protection: The integrated Battery Management System provides model-specific protection against conditions such as overcharge, excessive discharge, overcurrent, short circuits and unsafe temperatures.
• Rugged, model-specific enclosures: The current 60Ah Pro, 100Ah and 230Ah Elite batteries are IP67 rated, while the 230Ah Essential model is IP54 rated for dust and splashing. Check the exact model before installing a battery where spray, standing water or weather exposure may occur.
• Victron integration on select models: The 60Ah Pro and 230Ah V2 Elite platforms support communication with compatible Victron systems when the correct cables, firmware and configuration are used.
• 11-year manufacturer warranty: Every model currently shown in Epoch's 24V collection carries an 11-year warranty, with cycle-life ratings that vary by product. Review the individual listing and warranty terms before purchase.
