Hi, mine is without a letter, LCSC-part: C32254 (https://lcsc.com/product-detail/MOSFETs_Fortune-Semicon-FS8205_C32254.html).

My battery is 3.90v and the full light is always on when charging.Is this normal? Thank you!  :)

Stefan Wagner Reply

No, that's not normal. Are both LEDs on?

Emmm.The full light is always on but the charge light is flicker ing slightly.I use the same compenents and made two and they're all like this. I guess maybe I use the wrong compenents.I bought fs8205 from lcsc and they can't be wrong.I used DW01A.Thanks!

However both modules and batteries didn't become hot.

Stefan Wagner Reply

Is the fs8205 soldered the right way around? Can you drive a load via the board?

I sold it according to your picture above. Its output is around 4v.Really strange.😂

Stefan Wagner Reply

Maybe the TP4056 has a quirk ;-(
