I am just finish the wiring on my build and had a noob question about wiring in the charging jack. I have the jack as in the link below.
As I understand it, the outside barrel is negative and the pin in the middle is positive. So I should just use a multimeter to figure out which lead is which, and then connect the lead for the pin in the middle to the positive wire on my battery pack. Then lead for the outside barrel should be connected to the P-/CH- on the BMS?
I’ve never done this before, so wanted to get confirmation so I don’t start a fire!
