Re: Milwaukee battery out of balance

Do not over discharge. Or leave something in the battery. Running cutoff will only unbalance a battery. As a rule.

You can use an oven to melt the solder for the copper buss bars at 380 or 400 f . A toaster oven and use a clean coat hanger to press down.

That's a lot of money. There are bluetooth controllers out there. Plus that controller is over the top. Are you going to get a big motor in the future ?

Nice work. Well we know your not out drinking as all the money is going to your new love.
