Ok, this is what I have...tell me if this is ok, please. I have the board from a 510 PCC hooked to a tabbed 18650 and the + and - to the batty connectors, the red light is on, will it go off when the batty is fully charged or will it keep trying to charge it? Is there another way to hook it up? Previously, I also used a multi meter, found a 4.2v connection but it won't fire my atty, not sure why??
How about you tell us if it's ok : )
did you try it?
