I have a bunch of TP4056 modules in my mass charger. I have noticed they charge to about 4.22 volts, range is 4.20 to 4.25 volts. This is quite a bithigher than I would like. Is there any way of reducing the charge voltage to say 4.05volts? It would be great to have one common reference voltage fed to all the TP4056 modules so they all charge to exactly the same voltage. Has any clever electronics person experimented with this?
