Hello

[@ndamuramnelson5779]

Can't work fine for long.
He got the voltage right but how about the amps?
The amps would be x3 and that's bad for the circuit board.
The resulting capacity would be the total capacity of all the batteries divided by 3.
That's not much of an upgrade

Same voltage bro 3 - 3.7 voltage

Are you sure?
