my XR 20v tool has 4x terminals, 2 are negative & positive, the other 2 appear to be sensor wires (yellow/brown) (second from left & second right on battery top row) they go into the board (resin moulded) and back to the switch that powers the tool, what is sent from the battery via these two wires and how? Can you mesure with tester for me?
I ‘ ve the drill but not the battery and i want to male it with lipo. so need to supply the correct votlage/current to these wires so the tool will operate
any help here greatly appreciated!!
You are going to need to use not just a voltmeter you probably need a oscilloscope to read the information coming out of the pack, big power tool company’s wouldn’t make it that easy.
