Maintain a balanced battery

Monitoring the battery voltage and temperature to track the battery voltage, when the battery voltage changes over 10 mV, the circuit will start to deal with balance of the battery pack in the battery voltage different match. This balance through the "triage" the need for a balanced battery (maximum voltage of the battery) to achieve the current. Usually, a power transistor and the current limiting resistor in series, with the battery pack in parallel to control each battery balanced process. In the process of charging on-power transistor, the battery part of the current segregation, making it the rechargeable battery slower speed than the other. Discharge in the process of on-power transistors and increasing the battery of payload, making it the discharge rate faster than other batteries, in charge / discharge the battery mode balanced.
