36V trolling motor battery
A 36V 100Ah marine lithium battery with 3.84kWh of LiFePO4 power for serious trolling motor runtime.
The Epoch 36V 100Ah Marine Lithium Battery is a high-capacity 36V trolling motor battery, 36V lithium battery for boat upgrades, and deep cycle marine battery 36V solution for anglers who want long runtime without managing three separate 12V lead-acid batteries. Built with 3.84kWh lithium storage, IP67 waterproof protection, internal self-heating, Bluetooth battery monitoring, and an advanced BMS, it is engineered to keep compatible 36V trolling motors running from dawn until dusk.
One lightweight 36V LiFePO4 drop-in replacement for a traditional three-battery trolling motor bank.
Swapping a daisy-chain of three 12V lead-acid batteries for one 36V 100Ah marine lithium battery simplifies your boat’s electrical layout, opens up valuable compartment space, and removes substantial weight from the hull. That means less clutter, fewer interconnect cables, and a cleaner installation for modern fishing boats.
This battery measures 20 in L × 10.25 in W × 11 in H and weighs approximately 75 lb. Before installation, confirm your tray space, hold-down system, cable routing, terminal clearance, charger profile, and trolling motor manufacturer requirements.
3.84kWh lithium storage for Minn Kota, Garmin, Lowrance, and other compatible 36V trolling motor systems.
With 100Ah of capacity, 3.84kWh stored energy, and 120A continuous discharge capability, this 36V deep cycle lithium battery is built for anglers who spend long days on the water. LiFePO4 chemistry delivers a flatter discharge curve than lead-acid, helping your trolling motor maintain stronger, more consistent thrust through most of the battery’s usable capacity.
Use it with compatible 36V trolling motors from brands such as Minn Kota, Garmin, and Lowrance when voltage, current draw, fuse protection, charger profile, and manufacturer battery requirements match. For extended runtime, matched batteries may be wired in parallel up to Epoch’s stated limit of four batteries.
A heated marine lithium battery for cold-weather charging support.
Internal self-heating helps warm the cells before charging in freezing conditions, supporting safe charging for early spring, late fall, and cold-morning fishing trips. The advanced BMS also includes low-temperature charge protection to help protect the internal cells.
Fully dustproof and sealed for harsh marine environments.
The IP67 waterproof 36V battery enclosure is designed to protect the internal BMS and cells against dust, spray, heavy rain, and wet boat compartments. It is rated for temporary immersion up to 1 meter for 30 minutes, but should still be mounted securely and protected from long-term submersion or pressure washing.
A Bluetooth trolling motor battery monitor in your pocket.
Built-in Bluetooth connects to the Epoch app so you can check state of charge, voltage, current, cycle data, and battery status from your smartphone. It helps eliminate battery guesswork when you are miles from the ramp and need to know exactly how much power remains.

Full technical details, dimensions, weight, current ratings, and 36V charging settings.
Built for spray, rain, wet decks, and harsh boat environments.
The IP67-rated enclosure is fully dustproof and rated for temporary immersion up to 1 meter for 30 minutes. It is a strong choice for marine trolling motor installations where rain, salt spray, vibration, and moisture are part of normal use. For best results, keep terminals clean and protected, secure the battery properly, and avoid long-term submersion or pressure washing.
More usable energy. Less maintenance. More confidence on the water.
LiFePO4 technology provides stable voltage output, fast charging capability, long service life, and maintenance-free operation. Compared with traditional lead-acid trolling motor banks, this lightweight 36V battery simplifies installation while delivering efficient usable energy, smart monitoring, and rugged marine protection.
Verify your boat, charger, and trolling motor before installation.
Always confirm compartment dimensions, cable clearance, M8 terminal compatibility, charger compatibility, fuse sizing, trolling motor current requirements, and manufacturer guidance before installation. Use a lithium-compatible 36V charger or programmable charging system set to Epoch’s recommended parameters. For parallel banks, use matched batteries of the same model, age, capacity, and state of charge.
Frequently asked questions
Common questions about trolling motor runtime, boat fitment, charging, waterproofing, Bluetooth monitoring, and parallel battery banks.
Yes. For most tournament and weekend anglers, this 36V 100Ah marine lithium battery provides serious all-day trolling motor runtime. Because LiFePO4 delivers a flatter discharge curve than lead-acid, your 36V trolling motor can maintain more consistent thrust through most of the battery’s usable capacity. Runtime varies with thrust setting, boat weight, wind, current, motor efficiency, and how aggressively the motor is used.
No. This is a 36V lithium battery for boat and trolling motor systems, so it must be charged with a dedicated 36V LiFePO4-compatible marine charger or a programmable lithium charger. A 12V charger or older lead-acid charger will not properly charge the battery and may cause the BMS to protect the cells by shutting down charge acceptance.
This battery is significantly more compact than a three-battery 12V lead-acid bank, but you should measure your compartment before ordering. The case measures 20 in L × 10.25 in W × 11 in H and weighs approximately 75 lb. Confirm tray space, hold-down straps, terminal clearance, cable routing, ventilation, and charger compatibility before installation.
Yes. You can wire matched 36V 100Ah batteries in parallel to increase capacity. For example, two batteries in parallel create a 36V 200Ah bank for extended runtime. Do not wire this model in series to increase voltage beyond the battery’s 36V class rating.
Yes, in compatible 36V systems this single LiFePO4 drop-in replacement can replace a traditional bank of three 12V lead-acid trolling motor batteries. It simplifies wiring, frees up compartment space, and can significantly reduce boat weight. Always confirm your trolling motor voltage, charger profile, cable size, fuse protection, and manufacturer requirements before replacing an existing bank.
This battery is designed for compatible 36V trolling motor systems, including many setups using Minn Kota, Garmin, Lowrance, and other major marine trolling motor brands. Confirm that your motor is a 36V model and that its current draw, wiring, fuse protection, and manufacturer battery requirements match before installation.
Yes. This model is listed with an IP67 waterproof enclosure, meaning it is fully dustproof and rated for temporary immersion up to 1 meter for 30 minutes. For best long-term reliability, install it in a secure battery compartment and avoid pressure washing, damaged seals, or prolonged submersion.
Yes. Built-in Bluetooth connects to the Epoch app so you can view key battery data such as state of charge, voltage, current, battery status, and cycle information from a compatible iOS or Android device. This helps reduce guesswork while fishing.
The internal self-heating system helps warm the cells before charging in cold conditions. This supports safer cold-weather charging for early spring and late fall fishing, while the BMS provides low-temperature charge protection to help prevent cell damage.
No. This is a 36V deep cycle marine battery for trolling motor and compatible 36V power applications. It is not designed for engine cranking or outboard starting. Use a dedicated cranking-rated battery for engine starting applications.
