The Foxygen 12V 300Ah LiFePO4 Lithium Battery with Bluetooth & Self-Heating is a ultra-high-capacity deep-cycle leisure battery engineered for large campervan, motorhome, marine, and off-grid power builds. Combining 3.84kWh of usable energy with automatic sub-zero self-heating and a heavy-duty BMS, it provides maximum off-grid independence in all weather conditions. Key Features Integrated Self-Heating System: Automatically activates internal heating elements when connected to a charger in freezing temperatures (below 0°C), allowing safe charging down to -20°C. Massive 3.84kWh Capacity: Delivers 300Ah of usable storage in a single housing, eliminating the need to wire multiple smaller batteries together while saving weight and space. Heavy-Duty 200A BMS Output: Features a 200A continuous Smart BMS (up to 300A surge) to effortlessly run 2000W–3000W inverters for high-power appliances like induction hobs, coffee machines, and air conditioning units. Smart Bluetooth Monitoring: Integrated Bluetooth module connects to your smartphone for real-time tracking of State of Charge (SOC), voltage, charge/discharge current, and cell temperature. Long-Life LiFePO4 Chemistry: Rated for over 3,500+ deep discharge cycles at 80% DoD, providing up to 10 years of reliable daily performance. Significant Weight Savings: Weighs approximately 28 kg—offering roughly 60% weight savings compared to an equivalent lead-acid or AGM battery bank (~80+ kg).
