The battery provides 1280Wh of nominal energy. Actual runtime depends on the power consumption of your connected devices, inverter efficiency, battery state of charge, temperature, and other operating conditions.
As a simple reference, runtime can be estimated by dividing available battery energy by the total wattage of your loads. Higher-power appliances will reduce runtime, while solar or other charging sources can extend your time off-grid.

The battery supports up to 100A continuous discharge. At the nominal voltage of 12.8V, this represents approximately 1280W of DC power before inverter losses.
When selecting an inverter, make sure the battery's continuous current remains within its rated limit and consider inverter efficiency, startup surge, cable size, fuse protection, and actual appliance load.

Use a charging system designed or properly configured for 12V LiFePO₄ batteries.
The battery can be integrated with compatible:
- LiFePO₄ AC chargers
- Solar systems with an appropriate charge controller
- Vehicle DC-DC chargers
Follow the approved charging voltage and current specifications for this battery. A compatible LiFePO₄ charger in the 14.4–14.6V range is generally appropriate for this 12V battery system.

The built-in battery management system includes low-temperature charging protection to help prevent charging under unsuitable cold-temperature conditions.
If low-temperature protection is activated, charging may temporarily stop until the battery temperature returns to the permitted operating range. Do not bypass the BMS protection.

The compatible Bluetooth app allows you to check key battery information from your phone, including available data such as:
- State of Charge (SOC)
- Battery voltage
- Current
- Charging / discharging status
Keep your phone close to the battery and use the compatible app to search for the battery rather than pairing only through the phone's standard Bluetooth settings.

Yes. This model supports system expansion up to 4S4P when compatible batteries are properly configured.Series connections can increase system voltage, while parallel connections can increase total capacity.
For multi-battery systems, use batteries of the same model and similar condition, and follow proper wiring, fuse, cable-sizing, and connection requirements.

No. This battery is designed as a deep-cycle LiFePO₄ energy-storage battery and is not intended for engine-starting applications.
It is suitable for compatible RV, camper, solar, off-grid, and auxiliary power systems, but a dedicated starting battery should be used for engine cranking.

The BUKNUWO 12V 100Ah Bluetooth LiFePO₄ battery is backed by a 5-year warranty, subject to the applicable warranty terms.
Keep your order information and register your battery through the BUKNUWO warranty page. If you need help with Bluetooth connectivity, charging, installation, or battery operation, contact BUKNUWO customer support for assistance.
