Foxygen 12V 105Ah Lithium Leisure Battery

105Ah LiFePO4 lithium leisure battery with Bluetooth monitoring, self-heating and a 12-year warranty — ideal for weekend campervan trips and lighter off-grid setups

The Foxygen 105Ah lithium leisure battery is a premium LiFePO4 battery built for campervans, motorhomes and off-grid use. With 105Ah of usable capacity, built-in Bluetooth battery percentage monitoring and switchable self-heating for winter charging, it handles everything a weekend van build needs — lights, USB charging, a compressor fridge, and 12V loads. At just 10.6kg, it's less than half the weight of an equivalent AGM battery, and with up to 6000 cycles it'll outlast traditional leisure batteries many times over. The integrated Smart BMS protects against overcharge, over-discharge, overcurrent and temperature extremes, while the Bluetooth app lets you check voltage and status from your phone. The self-heating function means you can charge safely in sub-zero conditions. If you're upgrading from AGM or looking for your first lithium leisure battery, the Foxygen 105Ah hits the sweet spot between capacity, price and features for smaller campervan electrics.

Key Features

Bluetooth Monitoring

Check battery voltage, state of charge and status directly from your phone via the free Foxygen app (Android and iOS). A Victron SmartShunt is needed if you're adding a Cerbo GX into your system.

Self-Heating for Winter

The built-in heating function allows safe charging in sub-zero temperatures down to -20°C. Simply switch it on when temperatures drop. This protects the LiFePO4 cells from damage that occurs when charging cold — a feature that makes this battery genuinely usable year-round.

6000 Cycles

At 80% depth of discharge, the Foxygen 105Ah is rated for up to 6000 cycles. That's daily cycling for over 16 years. Compare that to an AGM battery that might give you 200-300 cycles before significant capacity loss.

Smart BMS Protection

The integrated Battery Management System continuously monitors cell balance, voltage and temperature. It automatically disconnects if anything goes wrong — overcharge, over-discharge, overcurrent, short circuit or temperature extremes. This protects both the battery and your campervan electrical system.
