12V 314Ah LiFePO4 battery for your battery system
The YEAGULCH 12V 314Ah LiFePO4 battery is a rechargeable storage option with 314Ah rated capacity. Its nominal voltage is 12.8V and its nominal energy is 4,019.2Wh. Match these ratings to the voltage and energy requirements of your equipment before choosing a battery.
The 314Ah capacity is distinct from the 300Ah model. Compare nominal energy, the listed dimensions and the model-specific operating limits when deciding which battery suits the project.
Plan your 314Ah deep cycle battery installation
Start with the power used by each appliance and the hours it will operate. Add those energy requirements to estimate daily demand. The nominal energy rating is a comparison figure, not a guaranteed runtime. Actual usable energy depends on the load, operating conditions, permitted depth of discharge and conversion losses.
When choosing a 314Ah deep cycle battery, check current capability separately from capacity. Review the model's BMS limits, inverter requirements, cable sizes and protective devices. Confirm that the battery enclosure and connections suit the installation. Do not assume that a battery is compatible simply because its capacity is larger.
Charging and equipment compatibility
Use charging equipment that supports the selected LiFePO4 model. Check the listed 14.6V charge voltage against the charger settings. The recommended current and temperature limits must also match the model documentation. Charging time depends on the starting state of charge and the actual charger output.
For solar storage, review the charge controller and inverter together. For mobile or auxiliary-power installations, check how the battery will be charged and secured. Ask about the exact configuration before connecting batteries together or changing an existing charging system.
Read the YEAGULCH user manuals for model documentation. For help choosing a battery, send your application and requirements, including daily energy use, required quantity and delivery location. For end-of-life information, see the US EPA guidance on used lithium-ion batteries and consult local collection services.
Frequently asked questions
How much energy does the 12V 314Ah LiFePO4 battery store?
