Specifications:
- 25.6V nominal, 100Ah and 2.56kWh of LiFePO4 for 24V systems
- 120A continuous discharge, with 200A available for up to 60 seconds
- 50A continuous charge from a LiFePO4-compatible 24V charger
- Internal heating, with cells charging from 32°F to 131°F (0°C to 55°C) and discharging down to -4°F (-20°C)
- Bluetooth app shows state of charge, current, voltage, cell temperatures, cycle count and state of health
- IP67 ABS case weighing 48.5 lb (22 kg)
- Up to four in parallel for 400Ah at 24V, or two in series for a 48V system

About the Epoch 24V 100Ah Lithium Battery
A 24V trolling motor usually runs on two 12V batteries, a jumper cable and a two-bank charger. The Epoch 24V 100Ah swaps the pair for one battery. You get one positive, one negative and 48.5 lb to lift in and out of the compartment. Self-balancing LiFePO4 cells and a built-in battery management system take care of the upkeep.
It has the current to match. It runs 120A continuous and 200A for up to 60 seconds. Check the maximum draw on your motor's spec label. A motor at or under 120A runs inside the continuous rating, and the short-term rating leaves headroom on top.
24V Trolling Motor Battery Runtime: Planning Around 100Ah
Run time depends on your thrust setting, wind, current and boat weight. To plan, divide the 100Ah capacity by your motor's average draw. At a 20A average, that's roughly five hours of nominal capacity, so keep a reserve for the run back to the ramp. The Bluetooth app shows live current, voltage, state of charge and cell temperatures. After a few trips, you'll know exactly what your boat uses.
Heated, IP67 Lithium Trolling Motor Battery for Cold, Wet Days
The IP67 case is dust-tight and rated for temporary immersion, so spray, rain and a wet deck are all part of the job. Secure it in a compartment, not permanently underwater. Internal heating and a discharge rating down to -4°F (-20°C) keep it working on cold early-season mornings. The cells charge between 32°F and 131°F (0°C to 55°C).
Wiring 24V and 48V Banks, Charging and Fusing
Need more run time at 24V? Connect up to four in parallel (400Ah) through a busbar. You can also pair two in series for a 48V system. Use batteries of the same model, age, capacity and state of charge in any bank.
On the water, your 12V engine alternator can top it up through a DC-DC charger. Pick one with a 12V input and 24V output, like the Victron Orion-TR Smart isolated DC-DC charger.
Size the cable to the motor's draw and the length of the run. Our custom battery cables are made to order from 6 AWG to 4/0 AWG, so each run fits your boat exactly. Protect the positive lead with the breaker or fuse your motor maker specifies, mounted close to the battery.
A Victron 275A battery switch in the positive lead lets you shut off the motor circuit for trailering and storage.

Frequently Asked Questions
Yes, as long as the motor runs on 24V. Take out the series jumper between the old batteries and land the motor's positive and negative leads on this battery. Then switch charging over to a 24V LiFePO4 charger. Before the first run, make sure the battery fits your tray or compartment and the hold-down secures it.
You need a 24V charger with a LiFePO4 (lithium) profile, like an onboard marine charger with a 24V lithium setting. A two-bank charger built for a pair of 12V batteries charges each bank separately, so it can't charge a single 24V battery.
Continuous charge current tops out at 50A, so pick a charger rated 50A or less.
Yes, with 24V equipment. Keep the inverter's continuous DC draw within 120A. That's about 3,070W at 25.6V nominal, before inverter losses. Set your chargers and solar charge controllers to a LiFePO4 profile.
Charge it before layup. Store it between 32°F and 95°F (0°C to 35°C), where Epoch rates storage for up to a year. Between -4°F and 113°F (-20°C to 45°C), it's rated for up to a month.
Epoch's warranty excludes damage from extended storage without charging, so top it up during long layups.
