Lithium-Ion Battery 42V 105Ah

42 V 105 Ah lithium battery — the flagship tier

3,780 Wh in 16.8 kg (10S configuration). The highest voltage in the LIFE range, for the most powerful powertrains.

Who is this battery for?

The largest motors and most demanding boats in 42 V. The lead-acid equivalent? ~250 kg and 100 litres — around ~15× the weight of the LIFE.

Featherweight: LIFE lithium vs lead-acid

For the same truly usable energy, an equivalent lead-acid battery would weigh ~248 kg and take up ~100 L (lead-acid only cleanly delivers ~50% of its capacity). The 42 V 105 Ah weighs only 16.8 kg for 47 × 37 × 18 cm: around 15× lighter, with no compromise on runtime.

What's inside

• 190 premium LG 21700 lithium-ion cells — 3,780 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).
• 10S configuration, 42 V, up to 3,600 W of power — available in 3 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.
