Nice video. We have been making then for close to 20 years know. We use the batteries that come with the 12 volt drills. This makes them potrable and low powered. This reduces the chance burning the controls in the drill housing. It also may not matter and we just keep doing the same way.
The drill motors are great for projects. We use them off many off season projects. We add anderson connectors and you can guess the powersource.
