12V Leisure Battery with Bluetooth & Heating FOX12V-300AH

The Foxygen 300Ah Lithium Leisure Battery is a high-performance 12V LiFePO4 battery with integrated Bluetooth monitoring, a Smart BMS and switchable heating, designed for reliable power in all conditions.

High-Quality Prismatic Cells

The battery is built with advanced prismatic cells that are certified to UL1973, UL9540, IEC62133, and IEC62619 standards. These cells deliver a cycle life of more than 3,000 cycles @100% DOD while maintaining excellent consistency and reliability over time.

Bluetooth Connectivity

An integrated Bluetooth system provides real-time monitoring of key battery parameters, including charge and discharge status, current, temperature, and cycle life. It also allows configuration adjustments for different applications, offering flexibility and enhanced control for lithium leisure battery use in a motorhome, RV, or off-grid setup.

Intelligent Heating System

For cold-weather performance, the battery features a uniform internal heating system that ensures the cells are warmed evenly. Unlike external heating blankets, which cannot sense internal cell temperature and often heat unevenly, this proprietary system draws power directly from the charging source and requires no additional components. The process is completely seamless: simply connect the battery to any compatible lithium charger, and the built-in heating and monitoring system automatically manages both heating and charging for reliable faster charging in low temperatures.
