Foursun 12V 100Ah LiFePO4 Leisure Battery 1280Wh, IP67

A reliable leisure battery is what lets a campervan or motorhome run lights, fridges, pumps and devices away from hook-up. This Foursun 12V LiFePO4 deep cycle battery is designed to replace traditional lead-acid batteries, offering more usable energy, a longer working life and much lower weight for extended off-grid travel and wild camping.

The 100Ah model stores 1280Wh, supports 4500+ cycles and weighs about a third of a lead-acid battery of the same capacity. LiFePO4 chemistry allows 100% depth of discharge, where lead-acid is usually limited to 40 to 50%, so you get far more usable capacity from the same rating. A built-in BMS provides cell balancing, under and over-voltage shutdown, short circuit and temperature protection. The ABS case is rated IP67 and self-discharge is under 3% per month. Up to four batteries can be connected in series or parallel (maximum 4S4P) for higher voltage or capacity.

It suits van conversions, motorhomes, boats, solar storage and backup power. This listing is the 12V 100Ah battery, supplied without a charger. When combining batteries, charge each fully first and use suitably thick cables. Follow the manual for installation, charging and fusing, and have wiring checked by a competent person. Its compact size also makes it easy to fit under a seat or bed.
