This project relates to these video “Cordless Drill Restoration Dewalt XRP 18V TYPE 1” https://youtu.be/opgJSd-tbbU which i restored just the drill and switch the old battery through the brand new one. Now I rebuild the old battery by upgrading it to Lithium battery with BMS 5S100A. This really is my first project by having an 18V battery power. I’ve found it’s more diverse from rebuilding 12V 3S and 14.4V 4S since i spent additional time in soldering. Even though it would be a little difficult, I learned something totally new from this. Personally i think really pleased with this result, battery has been doing perfectly.
