Then connect the jumper leads to the next cell, wait a few seconds for the previous BMS cell module to close the cell loop and reset the plastic box again. At 10A charging current, each cell took between 10 and 50 minutes, with an average around 25 minutes, to reach HVC. | Then connect the jumper leads to the next cell, wait a few seconds for the previous BMS cell module to close the cell loop and reset the plastic box again.
