The Ultimate 24V Trolling Motor Battery Upgrade
Drop two heavy lead-acid batteries and upgrade to one high-output lithium boat battery.
Replacing two 12V lead-acid batteries wired in series with a single 24V RV lithium battery or marine lithium battery can simplify your electrical system, reduce cable clutter, and cut significant weight from the boat. At just 48.5 lb, the Epoch 24V 100Ah LiFePO4 battery can help improve draft, handling, and available storage space compared with many traditional lead-acid banks.
LiFePO4 chemistry delivers a constant voltage curve, helping compatible trolling motors maintain strong thrust deeper into the battery’s usable capacity instead of gradually fading as voltage drops.
Built for Harsh Marine Environments
IP67 Waterproof & Dustproof
This waterproof trolling motor battery is IP67 rated, meaning it is protected against dust, spray, wet bilges, heavy rain, and temporary water exposure. It is designed for demanding marine compartments, rough-water vibration, and real-world boating conditions.
Internal Heating for Cold-Weather Anglers
Standard lithium batteries can be damaged when charged below freezing. This heated marine lithium battery uses internal heating technology to help warm the cells before accepting charge current in freezing conditions, supporting safer cold-weather charging down to -4°F / -20°C when properly configured.
Smart Power Management via the Epoch Bluetooth App
Know your state of charge before range anxiety ever sets in.
Built-in Bluetooth connects directly to the Epoch Li-Ion app, giving boaters real-time visibility into State of Charge, voltage, amp draw, temperature, cycle count, and battery status from a smartphone. This removes the guesswork from long fishing days and helps users make smarter power decisions while on the water.
Advanced Safety BMS & 11-Year Warranty
Smart protection, 3,500+ cycles, and long-term warranty confidence.
The built-in Smart BMS protects against overcharge, over-discharge, over-current, short circuit, and high or low temperature conditions. Combined with 3,500+ cycle life, maintenance-free LiFePO4 chemistry, and Epoch’s 11-year manufacturer warranty, this battery is built for long-term marine and RV power confidence.

Frequently asked questions
Epoch 24V 100Ah Marine Lithium Battery FAQs
Common questions about trolling motors, charging, waterproofing, runtime, Bluetooth monitoring, and RV house battery replacement.
Will this battery work with my 24V trolling motor?
Yes. With a 120A continuous discharge rate and 200A peak discharge rating, the Epoch 24V 100Ah marine lithium battery is designed for compatible 24V trolling motors, including many setups from Minn Kota, Garmin Force, Lowrance Ghost, and MotorGuide. It provides stable LiFePO4 voltage delivery so your motor can maintain strong thrust through the battery’s usable capacity.
Can I replace two 12V lead-acid batteries with this single 24V battery?
Yes. Instead of wiring two heavy 12V lead-acid batteries in series, upgrading to this single 24V battery simplifies wiring, frees up space in the console or bilge, and reduces boat weight. This battery weighs 48.5 lbs and stores 2.56kWh of energy in one compact lithium package.
How long will a 24V 100Ah battery run my trolling motor?
Runtime depends on wind, current, boat size, motor efficiency, prop load, and thrust setting. A 24V 100Ah LiFePO4 battery stores 2.56kWh of usable energy, and lithium’s flatter voltage curve helps maintain consistent trolling motor performance deeper into the day than lead-acid batteries.
Can I wire these batteries in parallel or series to increase capacity?
Yes. Epoch lists this model as supporting up to four batteries in parallel for a 24V 400Ah bank. It can also be wired up to two in series for compatible 48V systems. Use matched batteries of the same model, age, capacity, and state of charge, with properly sized cabling, fusing, and charging equipment.
Do I need a special charger for this marine lithium battery?
Yes. For best performance, use a 24V LiFePO4-compatible marine charger, RV converter, solar charge controller, inverter charger, or DC-to-DC charger with a dedicated lithium profile. For a 24V system, bulk/absorption charging should be set in the 28.4V–29.2V range and should not exceed the listed 29.2V maximum charge voltage.
Is the battery safe if water gets in my boat?
Yes. This battery is IP67 rated, meaning it is dustproof and waterproof for harsh marine environments, including heavy rain, spray, wet bilges, and temporary immersion up to 1 meter for 30 minutes. It should not be permanently installed underwater or exposed to avoidable physical damage.
Does the internal heater drain the battery while I am fishing?
No. The internal heating function is powered by incoming charge current when charging in cold conditions. It warms the cells to a safe charging temperature before normal charging resumes and does not pull power from the battery to heat the cells while you are actively discharging it on the water.
How do I monitor the battery’s charge level?
The built-in Bluetooth battery monitor connects to the Epoch Li-Ion app for compatible iOS and Android devices. You can check state of charge, voltage, amp draw, cycle information, temperature, and battery status directly from your smartphone.
Can I use this as an RV house battery replacement?
Yes, this battery is a strong 24V RV lithium battery option for RVs, camper vans, and off-grid power systems that are designed around 24V equipment. Always verify inverter voltage, converter or charger settings, cable sizing, fuse protection, and installation requirements before replacing an existing RV house battery bank.
