Lithium-Ion Battery 42V 155Ah

42 V 155 Ah lithium battery — the flagship

5,580 Wh in 23.2 kg. The most powerful and most enduring pack in the entire LIFE range.

Who is this battery for?

For the largest 42 V setups and no-compromise days. An equivalent lead-acid bank would weigh ~350 kg and take up 145 litres — the equivalent of a small cabinet.

Featherweight: LIFE lithium vs lead-acid

For the same truly usable energy, an equivalent lead-acid battery would weigh ~352 kg and take up ~145 L (lead-acid only cleanly delivers ~50% of its capacity). The 42 V 155 Ah weighs only 23.2 kg for 47 × 37 × 18 cm: around 15× lighter, with no compromise on runtime.

What's inside

• 280 premium LG 21700 lithium-ion cells — 5,580 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).
• 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.
