Tips. BG1F use "Coulomb Accumulation", called "CA", methods to calculate the fuel status of a battery pack. This method measures the current flow-in or flow-out from the battery-pack, and then multiplied by timer measured, the product of "CA" and "Time" give a accurate energy level of flow-out or flow-in. Use BG1F-xx need a "current resistor" series between "Battery Cell Negative pole" and battery-pack negative terminal. Generally this resister could be the existing RS on the PCM or BMS of battery-pack, or could be an external component of this battery-pack. The recommended value of this RS is 5mΩ~50mΩ, depend on the working current of this battery-pack. , BG1F LiFePo4 battery-pack fuel gauge has a +-10% relative remain capacity tolerance.
