BQ77216: BQ7721614PWR ,bypass middle cell

Hello Liu,

Thank you for your patience. You should be fine to short unused cells to reduce the cell count. The inputs are usually shorted at the IC. 

Please refer to this BQ77216: How do I reduce the cell count? FAQ as well as Section 3.2 Reducing the Cell Count from the EVM User Guide for further details.

Best Regards,
Alexis
