Why should lithium battery packs be balanced
Cell voltages and battery temperature are monitored by the battery itself. If they are outside the normal range, an alarm is sent to the BMS. In order to protect the battery, the BMS will then turn off loads and/or chargers or generate a pre-alarm as soon as it has received the appropriate signal from the battery.
