147 147  The BMS Mini is powered directly from the battery. This causes the voltages of the first and last battery cells to be measured with an error, the magnitude of which is proportional to the current drawn by the BMS and the resistance of the wires connecting these cells to the BMS. To compensate for the cell voltage measurement error, the BMS Mini provides a wire resistance setting.
