The battery indicator figure out fuel status of a battery pack on measuring current flow-in and flow-out from battery pack. Using GBG1-Fxx need a 'current resistor' series between 'battery cell negative pole' and batter pack negative terminal. Normally the resistor is the existing RS on the PCM or BMS of battery pack, or is an external component of this batter pack. Recommended value of this RS is 5mΩ-50mΩ, depending on the working current of battery pack. The battery fuel gauge has a +-10% capacity measuring remaining capacity.
