ECO WORTHY 12V 280Ah LiFePO4 Lithium Leisure Battery with Bluetooth, Low Temp Protection,6000+ Cycles for Motorhome, Shed, Marine,Home Energy Storage

Bluetooth 5.1 App Monitoring:The integrated Bluetooth 5.1 module (≤15m range) pairs with the ECO-WORTHY app to deliver real-time monitoring of voltage, current, remaining capacity (SoC). Remotely track performance indicators, optimize power usage, and prevent unexpected power outages during application Low-Temperature Protection:This 12V lithium battery features a 200A BMS with multiple protections, including low-temperature protection. Charging stops below 19.4°F (-7°C) and resumes above 32°F (0°C), while discharging halts below -4°F (-20°C) to prevent damage, ensuring stability in harsh conditions Reinforced Structural Integrity with Metal Frame:An internal high-strength metal compression frame stabilizes LiFePO4 cells, reducing vibration-induced damage during transit and preventing long-term cell expansion. This design extends cycle life in mobile installations like motorhomes, marine vessels, or off-grid solar setups Application: The 280Ah Lithium Iron Phosphate Battery has 3584Wh Energy, and can be expanded to 28.67kwh by wired in 4P2S/2P4S, Perfect for motorhomes,campervan, marine, travel trailer, off-grid solar power system etc Charger Recommendation: For optimal charging, we recommend using the ECO-WORTHY 12V/24V 20A LiFePO4 battery charger (ASIN:B0F21ZDMBJ) with 0V activation function, which will fully charge this 12V 280Ah battery in approximately 14 hours. Alternatively, it can be charged in about 6 hours with a 600W solar panel, or in 14 hours with a 20A DC generator.
