I've designed a circuit around the tp4056 with DW01A and FS8205A included, as well as load sharing capabilities.

beneath circuit is what i use (minus load sharing)

now that i'm sourcing lipo batteries, i see most of them have a protection circuit already build in with the same DW01A and FS8205A...

1) so, will the charging still work having a "double protection circuit"?
2) will it be safe?
3) if it works, would it be more/less efficient?

thank you for taking the time to figure this out with me!
