5 Cell Balancing Consideration

The bq27426 device has no cell-balancing capability, and the use of a voltage divider does not provide any individual cell information. Therefore, is up to the pack maker and the original equipment manufacturer to make sure that the 2 cells in series are not out of balance and that the safety of the pack is maintained.
