Humsienk LiFePO4 Leisure Battery 12V 100Ah, Campervan RV

A healthy leisure battery is the heart of any campervan or motorhome electrical system. The Humsienk 100Ah LiFePO4 battery replaces heavy lead acid batteries with lithium iron phosphate chemistry, giving you more usable energy for lights, fridge, water pump and devices while saving space and weight in your van.

At a nominal 12.8V and 100Ah, it delivers steady power through most of its discharge, and lithium iron phosphate is known for a long cycle life compared with lead acid. A built-in 100A BMS protects the cells and disconnects the battery if the discharge current exceeds 300A (plus or minus 50A). The battery operates from -20°C to 70°C and includes automatic cut-off below -20°C to help protect it in freezing conditions. Measuring 26 x 17 x 21 cm and weighing 8.95 kg, it is designed to fit a Group 24 battery box, which simplifies replacement. Up to four batteries can be connected in series or parallel for larger systems.

This battery suits van conversions, motorhomes, caravans, boats and solar storage projects where reliable deep cycle power matters. It is a strong upgrade for anyone adding solar panels or a larger inverter. Always follow the manual for installation, use a charger suited to LiFePO4 and fit appropriate fusing and cabling.
