Lithium-Ion Battery 37,8V 155Ah

37.8 V 155 Ah lithium battery — long runtime in 36 V

5,022 Wh in 21.2 kg. The largest 36 V capacity in the range, for the biggest days without ever easing off.

Who is this battery for?

For large 36 V motors and long-duration outings. The lead-acid equivalent would exceed 260 kg and 110 litres: here, 21.2 kg is enough.

Featherweight: LIFE lithium vs lead-acid

For the same truly usable energy, an equivalent lead-acid battery would weigh ~264 kg and take up ~110 L (lead-acid only cleanly delivers ~50% of its capacity). The 37.8 V 155 Ah weighs only 21.2 kg for 47 × 37 × 18 cm: around 12× lighter, with no compromise on runtime.

What's inside

• 252 premium LG 21700 lithium-ion cells — 5,022 Wh, 155 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 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.
