Parallel LiPo Battery System

[Kuusou]

I'm seeking feedback on the design of a parallel lithium polymer battery system shown in the attached schematic. The primary goal is to safely combine two individual battery packs to increase system capacity while preventing any negative side effects, such as mutual influence between cells.



Design Details:
Battery Management System (BMS): BRCL3130ME
Datasheet: https://wmsc.lcsc.com/wmsc/upload/file/pdf/v2/lcsc/1811141355_Foshan-Blue-Rocket-Elec-BRCL3130ME_C328560.pdf

Charging IC: PJ4054B
Datasheet: https://wmsc.lcsc.com/wmsc/upload/file/pdf/v2/lcsc/2110272230_PJSEMI-PJ4054B_C2911335.pdf

Low Voltage Cutoff: APX803S-31SA-7
Datasheet: https://wmsc.lcsc.com/wmsc/upload/file/pdf/v2/lcsc/1811141622_Diodes-Incorporated-APX803S-31SA-7_C129757.pdf

P-Channel MOSFET: AS3423B
Datasheet: https://wmsc.lcsc.com/wmsc/upload/file/pdf/v2/lcsc/1912111437_FMS-Formosa-Microsemi-AS3423B_C341542.pdf

Questions:
Do I need to add Schottky Diodes between the APX803S-31SA-7 and each LiPo cell before they are connected in parallel to prevent mutual influence?

Is the current layout needlessly complex? Can the individual battery packs (same manufacturer and rating) be combined in parallel safely without all these extra components? For example, could they be connected together in parallel with each cell only having it's own BMS and use one charging IC? Are my concerns with the batteries influencing each other and equalizing valid?

Any insights or recommendations for improving this design would be greatly appreciated.
