Integrated BMS Protection

The upgraded battery-management system provides manufacturer-listed protection for over-charge, over-discharge, over-current, short circuit, high/low temperature and charging current, with cell balancing. These features do not replace suitable fusing, isolation, cable sizing or installation practices.

Inverter and Load Compatibility

The 100A continuous-discharge rating is the relevant BMS limit for sustained loads. The 200A specification is a pulse rating for no more than one second. Check the intended inverter’s DC input at the actual AC load, including efficiency losses and start-up surge.

Appliances such as fridges, air conditioners and kettles vary widely in demand. Do not assume compatibility from the appliance category alone.

Charging and Battery-Bank Configuration

Use LiFePO4-compatible charging equipment within the 50A maximum charge-current and 14.6V cut-off limits. Charging is specified from 0°C to 50°C.

The manufacturer lists a maximum 2S/2P configuration. Only connect identical batteries of the same model, age and state of charge, and follow the current manual for balancing, cable and protection requirements.

Frequently Asked Questions

Is 200A the continuous output?

No. The listed continuous-discharge limit is 100A; 200A is available only as a pulse for up to one second.

Can it be charged below 0°C?

The listed charging range begins at 0°C. Do not charge below that temperature unless current manufacturer instructions specifically permit it.
