Foxygen 12V 105Ah LiFePO4 Leisure Battery with Bluetooth & Self-Heating
Product Description
The Foxygen 12V 105Ah LiFePO4 Lithium Battery with Bluetooth & Self-Heating is a compact, deep-cycle leisure battery engineered for campervans, motorhomes, marine craft, and off-grid setups. Built with active internal heating elements, it charges safely in sub-zero environments where standard lithium batteries fail or risk permanent cell damage.
Key Features
-
Integrated Self-Heating Technology: Features an automated heating element that warms internal cells when connected to a charger below freezing (0°C), enabling safe charging down to -20°C.
-
Smart Bluetooth Monitoring: Built-in Bluetooth connectivity allows real-time tracking of State of Charge (SOC), cell voltage balance, temperature, and cycle count via a mobile app.
-
Drop-In Lead-Acid Replacement: Standard DIN / EN casing dimensions make it a direct drop-in replacement for traditional 85Ah–110Ah AGM or Gel leisure batteries.
-
High-Continuous BMS Output: Equipped with a 100A continuous Intelligent BMS (200A peak surge) to run moderate AC loads via inverters up to 1200W.
-
Grade-A LiFePO4 Cell Longevity: Delivers over 3,500+ deep discharge cycles down to 80% DoD—providing up to 10 years of reliable daily power.
-
Extremely Lightweight: Weighs approximately 10.5 kg—saving over 60% of weight compared to equivalent lead-acid/AGM batteries.
