12V 300Ah Lithium LiFePO4 Battery with APP Monitoring, 200A BMS Rechargeable Starting Battery with 2PCS Battery Tie Down Straps, Perfect for RVs, Solar, Boats, Off-Grid,Home Energy Storage

Features

• 2-in-1 Smart Battery: Energy Storage & Starting BatteryThe BMS's intelligent dual-mode control gives the battery two identities. In normal mode, it acts as a 300Ah deep-cycle battery with over 5,000 cycles for backup power. In startup mode, the BMS switches to Power Mode, delivering 1,500A instantaneous current by leveraging the high-rate discharge capability of LiFePO4 cells. Our upgraded technology provides isolated protection, ensuring high-current surges never compromise cycle life.
• High / Low Temp Cutoff With high temp cutting off prevents charging/discharging over 167 F (75C). And Low temp cutoff protection prevents battery damage in low-temperature environments. The battery can operate from as low as - 4 (-20) to as high as 140 (60).
• Superior Safety with Upgraded 200A BMS Equipped with an upgraded 200A BMS and Grade A Cells. The battery is safeguarded against overcharging, over-discharging, overcurrent, short-circuiting, low/high temperature, and features auto-cell balance. A built-in 200A BMS protection plate automatically disconnects the battery when the discharge current exceeds a certain range, ensuring security and stability.
• Expandable Power Capacity Expand flexiblely from 3.84kWh to a maximum of 61.44kWh. With 16 identical 12V 300Ah LiFePO4 batteries wired in 4P4S, you can easily upgrade your battery system to meet different power needs. Whether for RVs, home backup, or off-grid living, it offers power output from 2.56kW to 40.96kW for various appliances.
• Fast Charging & Multiple Applications Supports 3 charging methods: solar, generator, and 14.6V 70A LiFePO4 charger. The 12.8V 300Ah LiFePO4 battery can be fully charged about 4.5 hours by a Solar Panel -MPPT (850W), faster than traditional lead-acid batteries. Ideal for multiple applications such as RVs, marine equipment, garden tools, off-grid, and various outdoor electronics.
• APP MonitoringThe APP can monitor battery voltage, current, power, SOC (State of Charge), and cycle count in real time. This data helps optimize charging (e.g., avoiding overcharging) to extend battery life.
