Otherwise, gain is used for have betters values for DIFFERENTS situations...

Re: check lipo battery level?
Yep, Finally it's a little bit dangerous. It depends of the power of the computer which is charging. For me it's allright with a raspberry computer, but just with a laptop, battery is very hot during charging. I will try to add a voltage regulator, but maybe this will stop the charging ability???

I have seen that it looks possible with the pyb-D and wbus28...
