Whether used to power electric marine motors or in large RVs, off grid properties, for on location audio visual equipment power, powering emergency “blue light” equipment or in commercial applications such as road signage, the Lifos 105 provides quick charging reliable power in all circumstances. The Lifos 105 provides an amazing 2750 charge / discharge cycles with a 95% depth of discharge giving a usable battery capacity of 99.75Ah.

Lifos 105 comes with a five year warranty.
