Yeah buddy, my original Sanwa battery failed so I bought this Protek 5500 pack. But, I became frustrated with it for the very reason you talked about. It would never finish charging, or it would say it’s was 4.20v but as soon as I stopped the charge it would drop in voltage. 😡 I shelved it and went back to the Sanwa Lipo.
