Vatrer 12V 300Ah LiFePO4 Battery with Self-Heating for RV and Off-Grid Power - 1 PACK

Keep Charging Through Freezing Mornings After a cold night in your RV or cabin, charging power can arrive before the battery itself has warmed up. When a charger is connected and the cell temperature is at or below 32°F, the BMS directs charging input to the heating system first instead of charging the cells. Once the temperature rises above 41°F, heating stops and normal charging begins automatically. With this self-heating lithium battery, you can leave the battery installed while the system handles the warm-up before solar, shore power, or vehicle charging replenishes your energy. 3.84kWh for Longer RV and Off-Grid Runtime A refrigerator running overnight, lights after sunset, a water pump, fans, electronics, and other daily loads quickly add up when hookups are not available. This Vatrer 12V 300Ah LiFePO4 battery stores 3.84kWh of energy, giving you more room to stay comfortable between charging opportunities. Whether you are boondocking in an RV or running a remote cabin, the larger battery reserve helps reduce your reliance on generator time or the next available power source. 200A BMS Power for High-Demand 12V Loads Turn on a coffee maker while your refrigerator, lights, and water pump are already in use, and current demand rises quickly. The built-in 200A BMS supports up to 2,560W of continuous output, giving this RV lithium battery the headroom for higher-demand 12V systems and inverter-powered appliances.
