Evaluating Charge and Discharge Currents

Bipolar power supplies will source or sink current to maintain the set voltage. When bipolar supplies are available, they may be used for both the battery and pack side of the board to allow charge and discharge currents without re-connecting the equipment. Be sure to set the supplies appropriately to prevent exceeding the ratings of the EVM.
