When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor. This very high current is at a minimum likely to age the contactors, it could permanently damage the contactors. Therefore, when we closed the contactors on the battery pack we do this in three steps:

Voltage Measurement: Attach multimeter probes to the battery and measure its voltage. The voltage should be something between the LVC (Low Voltage Cutoff) and HVC (High Voltage Cutoff) stated in the cell or battery''s datasheet. For NMC, this will be between 2.5 volts and 4.2 volts per cell. For an LFP cell or battery, it will be 2.5 to 3.7 volts.
