LPA422
This module is designed for Li-Ion battery packs with 3 and 4 cells and can be tailored according to your needs. This module contains a cell balancing system so that cells with a different charging status within a battery pack can be brought to the same charging status and capacity after a number of charge/discharge cycles. Leave the charger connected to the battery pack for a prolonged time to achieve cell balancing. The time required to balance the cells depends on the capacity of the cells, their differences in charging status as well as the set bleeding current of the LPA422.
