This is a very noob question, but where do I solder the positive and negative leads to this BMS I got?
See attached for pics. Do I solder the wire where the hole is? Or on the silver areas to the left or the right. Or can I simply solder anywhere along there? I tested the continuity with a multimeter and it seems that the entire silver areas are connected (i.e. the silver areas around the hole and the strips to the right and to the left.) So I’m thinking anywhere there is fine?
Just wanted to confirm so I don’t destroy this thing accidentally.
Looks like its all the same, probably best to use the holes to solder into though, unless soldering along the other pad areas makes installation easier.
Thanks! I just wasn’t sure what all that other surface area was for and if it was there for a reason. Will go through the hole as that will definitely be easiest.
I had done up this wiring diagram before receiving the BMS. Seeing that I have no CH-, do you know how I am suppose to wire the charging port? In my diagram I have it going to CH-, but that doesn’t exist on my BMS
I’m not sure what the discs are for your BMS or if it even detects individual cell voltage or charge protection… But it should be fine for your charge port to go to B+ and P-… Might want to double check add I’m not sure.
