Chinese Battery Angle Grinder to 12v barrel jack

thingiverse

You need 2 screws that fit or superglue, found some random ones laying around.Also might need a bit of sanding to fit and doesn't clip properly into the angle grinder.You will need a barrel jack and some sandpaper to make it fit nice and tight: https://www.adafruit.com/product/373Your also gonna need to solider some stuff as well, I used tinfoil and electrical tape for my contact pads and used more tape on the inside to keep it in place.It doesn’t seem happy with anything over 12.3v, I did some tests, and it only worked on a 12.2v car barrel plug, and the batteries it came with are 12.3v, so a volt thingy would b useful for checking if current is flowing or not. Also needs high amps, and if it turns on then off and on again trying to spin up, then its drawing too much current on startup and activating overvolt protection, to avoid this use a car barrel plug and a 12v car socket from your car or a battery bank such as the one I used called the jackery 240Jackery 240: https://www.amazon.com/Jackery-Portable-Power-Station-Generator/dp/B07D29QNMJCable: https://www.amazon.com/Cigarette-Lighter-Extension-Supply-Adapter/dp/B08F2D8TSS/ref=sr_1_6?keywords=12v+car+socket+to+barrel+plug&qid=1703488454&sr=8-6This only rlly useful for long jobs cause the batteries good for cutting locks n stuff.
