Ultimate Lithium 12v 24v 48v Batteries. Solar, Trolling Motors, Golf Carts! Teardown and Review
Epoch Batteries - Why I Made the Switch
Epoch 12V 100Ah Waterproof LiFePO4 Marine Battery, Best in Class?
-
Safety Data Sheet (LiFePO4)
-
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 the major trolling motor brands. 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.

Epoch Batteries Limited Warranty
11-Year Limited Warranty: 3 Years Free Replacement
- Years 1–3: free replacement
- Years 4–11: 40% off MSRP on a replacement battery
Epoch Batteries warrants this product to the original end-user purchaser to be free from defects in materials and workmanship under normal use and service for the warranty period above, when it is installed, operated, charged, stored and maintained as its manual describes. The warranty is not transferable and ends if the product is sold or given to someone else.
How the 40% Discount Works
After the free coverage ends and through Year 11, if the battery has a covered defect Epoch offers a new replacement of the same model (or a current Epoch model of equal or greater capacity and function) at 40% off Epoch's MSRP on the date of the offer. The offer covers one replacement per defective battery, bought directly from Epoch, and you pay the discounted price, any tax and shipping.
When Coverage Starts
Coverage starts on the date of your original purchase. To confirm that date, register the product with Epoch within 90 days of purchase or keep your proof of purchase (an invoice or receipt showing the product, purchase date and seller). If you can provide neither, coverage starts on the manufacturing date recorded for the product's serial number. A repaired or replacement product is covered for the rest of the original warranty period.
What Is Not Covered
The warranty covers defects in materials and workmanship only. It does not cover damage or failure caused by installation, wiring or system design that doesn't follow the manual (including undersized or damaged cables, poor crimps, loose or corroded connections and incorrect fusing); reverse polarity, short circuits or faults in the connected electrical system; series or parallel connections beyond the manual's limits, or mixing batteries of different models, capacities, ages or states of charge; a product not secured as the manual requires; charging outside the manual's voltage, current or temperature limits; discharge above the rated current, or engine starting with a battery not listed as a starting or dual-purpose battery; over-discharge, storage fully discharged, or storage for more than 3 months without recharging; accidents, impact, fire, flood, power surges, submersion or exposure beyond the product's IP rating; opening, modification or repair by anyone other than Epoch or an Epoch-authorized provider; removed or altered serial numbers; normal capacity loss and wear consistent with age and use; or cosmetic damage that doesn't affect performance. Using chargers and other equipment from other brands does not affect coverage by itself.
Obtaining Warranty Service
Start a claim through the Epoch Warranty Portal before the warranty period ends, with the model, serial number, proof of purchase or registration, a description of the problem and any photos, videos or app screenshots. If the claim qualifies, Epoch issues an RMA number with packing and shipping instructions; do not ship a product without an RMA. Epoch inspects and tests the product, typically within 3–10 business days after it arrives, and then repairs or replaces it, or makes the discount offer where applicable.
Shipping
You pay to ship the battery to Epoch; Epoch pays to ship an approved warranty repair or free replacement back to you. For discount replacements you pay shipping on the replacement battery. Packaging must follow the RMA instructions (lithium batteries are regulated hazardous materials in transport).
Visit Epoch's Warranty Page to review the complete warranty terms (effective October 17, 2026).
