12V 300Ah LiFePO4 battery for RV, solar and off-grid storage
The YEAGULCH 12V 300Ah LiFePO4 battery brings 300Ah of rated capacity and 3,840Wh of nominal energy to a compatible 12V-class system. Its nominal voltage is 12.8V. Use it as a deep-cycle storage battery for RV house power, solar storage and off-grid equipment when the electrical requirements match the model specifications.
A built-in 200A battery management system helps protect the battery during use. Plan the complete installation around the battery, charger, inverter, cables and protective devices together. The BMS is part of the battery protection system; it does not replace correctly sized wiring, fuses or an appropriate charger.
Plan your 300Ah deep cycle battery system
Start with the wattage of each appliance and the number of hours you expect to run it. Add those energy requirements before choosing a battery. The 3,840Wh rating describes nominal stored energy. Actual usable energy and runtime depend on operating conditions, the permitted depth of discharge, inverter losses and the connected load.
This battery is intended for energy storage. It is not an engine-starting battery and should not be used for starting devices, golf carts or jacks. For an RV installation, check the available battery compartment, mounting method and electrical connections before ordering. For a solar installation, confirm that the charge controller and inverter support the battery's voltage and charging requirements.
Charging and installation checks
Use a compatible LiFePO4 charger and check the listed 14.6V charge voltage against your equipment settings. The product specifications recommend a 50–100A charge current. Confirm the correct settings and temperature limits in the documentation for your selected model before charging. Charge time varies with the starting state of charge and the charger's actual output.
Review the YEAGULCH user manuals for model documentation, or compare the 12V LiFePO4 battery range if you need a different capacity. Send your application, daily energy use, required quantity and delivery location through our contact page for help with product selection.
Frequently asked questions
