Important Safety Information

Please read all safety instructions carefully before using the battery and charger. Failure to follow these instructions may result in electric shock, fire, or serious injury.

  • Charger Heat Dissipation: The included 4A charger dissipates heat through its outer casing during operation. It is normal for the surface temperature to become high and feel hot. Always place the charger in a well-ventilated area during use to ensure safety throughout the charging process.
  • Battery Connection: When connecting the charger to the battery terminals, prioritize the "vertical clamping" method. Attach the clamps to the battery terminals from the top and bottom direction for more stable contact and better conductivity.
  • Packaging: The 12V 50AH battery and 4A charger may be shipped in two separate packages. If you only receive one package initially, please wait patiently for the second package to arrive.
  • BMS Protection: The integrated 75A BMS provides protection against over-charge, over-discharge, over-current, short-circuit, and high-temperature conditions. Do not attempt to bypass or modify the BMS.

Setup and Charging

Unboxing and Initial Inspection

Upon receiving your DC HOUSE 12V 50Ah LiFePO4 Battery, carefully unbox all components. Verify that you have received the battery and the 4A charger. As noted in the safety section, these may arrive in separate packages.

Charging the Battery

Before first use, it is recommended to fully charge the battery. Use only the provided 4A charger or a compatible LiFePO4 charger with a 0V wake-up charging feature.

  1. Ensure the 4A charger is placed in a well-ventilated area.
  2. Connect the charger's output clamps to the battery terminals. Use the vertical clamping method for optimal contact. Red clamp to positive (+), black clamp to negative (-).
  3. Plug the charger into a standard AC power outlet.
  4. The charger will automatically begin charging. A full charge from 0% to 100% typically takes approximately 12.5 hours with the 4A charger. The charger's intelligent design manages Constant Current (CC) and Constant Voltage (CV) modes.
