The next generation of power storage is here! These LiFePO4 batteries weigh less than half of their Lead Acid counterparts. They may look fairly similar to lead acid batteries, but internally they’re a totally different, next generation concept. They’re actually made up of regular 18650 LiFePO4 cells, which are in mass production for many portable devices. An internal battery management system (BMS) ensures all cells are uniformly charged and discharged, as well as providing short circuit, over current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead acid battery which is unprotected, and can discharge rapidly under short circuit conditions, causing fire and damage. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells.

This 120Ah model can provide continuous current up to 50A with peaks of 100A. Absolutely perfect for portable power, and replacement of similar capacity lead acid / AGM battery.

- Much lighter than Lead Acid and AGM Batteries
- Robust LiFePO4 Cells
- 10+ years life span
- 1500+ cycles (>80% capacity)
