Lithium-Ion Battery 37.8V 101.3A

37.8 V 105 Ah lithium battery — for 36 V motors

3,402 Wh in 15.1 kg. Built for powerful 36 V setups, where an equivalent lead-acid bank would approach 190 kg and 75 litres.

Who is this battery for?

Large 36 V bow-mount motors (Minn Kota Terrova/Ulterra…) and demanding boats. The power of 36 V without the weight burden of lead-acid.

Featherweight: LIFE lithium vs lead-acid

For the same truly usable energy, an equivalent lead-acid battery would weigh ~186 kg and take up ~75 L (lead-acid only cleanly delivers ~50% of its capacity). The 37.8 V 105 Ah weighs only 15.1 kg for 42 × 34 × 20 cm: around 12× lighter, with no compromise on runtime.

What's inside

• 171 premium LG 21700 lithium-ion cells — 3,402 Wh, 105 Ah guaranteed, ≥ 500 cycles.
• Smart BMS: permanent protection against overcharge, deep discharge, short circuit and overheating.
• Waterproof shock-resistant case with built-in monitoring screen (voltage, remaining charge, consumption).
• 9S configuration, 37.8 V, up to 3,240 W of power — available in 5 finishes.

The LIFE differentiator: Bluetooth and supervision app

Beyond the built-in screen, the battery connects via Bluetooth to the LIFE app: state of health, real runtime and instantaneous consumption, straight on your smartphone. It's the Apple of lithium — nothing to configure, everything is factory-calibrated.
