WattCycle 12V 314Ah Mini LiFePO₄ Battery, Self-Heating 12V Lithium Battery with 200A BMS, Bluetooth App Monitoring, Compact Power for RV, Solar, Home Energy Storage, Solar, Off-Grid Use

• 🍃【Automatic Self-Heating for Cold Climates】The integrated self-heating system activates automatically when battery temperature falls below –4°F, ensuring safe charging in freezing environments. Combined with low-temperature discharge protection and high-temperature cutoff at 149°F, it delivers dependable performance for winter RV travel, marine storage, and off-grid cabins.
• 🍃【4.01kWh Mini Battery with High Energy Density】This 12V 314Ah Mini LiFePO₄ battery provides 4.01kWh of usable energy in a compact 15.12×7.64×9.76 in footprint—saving up to 50% installation space compared to lead-acid banks. The high 142Wh/L density supports extended runtime for RV systems, emergency backup, and solar storage.
• 🍃【EV-Grade A Cells with Long Cycle Life】Built using EV-grade A LiFePO₄ cells, offering 6,000+ cycles at 80% DOD and over 10 years of service life. Maintains stable voltage under continuous load, suitable for induction cooktops, space heaters, trolling motors, and off-grid household equipment.
• 🍃【200A Smart BMS with Fast Thermal Control】The 200A Smart BMS delivers full protection against over-current, over-voltage, over-discharge, short-circuit, and temperature extremes. Integrated aluminum heat-dissipation fins improve cooling efficiency by up to 30%, while the reinforced aluminum frame enhances shock resistance for mobile applications.
• 🍃 【Bluetooth Monitoring & Flexible Installation】 Bluetooth 5.0 connects seamlessly to the WattCycle App, displaying real-time SOC, voltage, current, and temperature. The Mini design fits under RV seats, storage cabinets, and boat consoles, supporting 1C charging via solar panels, generators, or LiFePO₄ chargers. Certified UN38.3, CE, FCC, and RoHS.
