BQ24104: Please help me review my schematic

Part Number: BQ24104

Tool/software:

Dear Sir:

              Please kindly help me review my charger design with BQ24104. Allow me to elaborate:

1. I plan to use two sets of charger with two sets of 2S1P batteries.

2. For the two chargers may be in different charging status, to prevent confusion, I use PMOS to separate their outputs.

3. When external power supply is gone, the PMOS would turn on, and batteries start working accordingly.

My latest schematic is attached, please kindly help me review and comment.

Thank you!TI BQ24104 Review 0502.pdf

Sincerely Yours
