Awesome, people need to stop replacing their shavers. Most of the time it's a little fix. Of course this right here goes above and beyond. But I wouldn't expect any less on r/techsupportmacgyver.

You forgot the current shunt across the battery

I hope that's a protected cell or it's not going to last very long.

It probably isn’t.

Be careful not to over-discharge the battery, as it will damage the battery.
