Thanks bro, that’s what i wanted to get an idea of
I can confirm my BMS looks identical to the first picture in your post.
I would uploads pics but it seems I am not allowed(?)
In the manual provided with my BMS it says to connect P2 last pin to pack B+ no matter the configuration, which makes sense given the spec in the manual you linked says it’s what powers the protection board (is that just another word for the BMS or is there a difference?).
I had a chat with the ali store and they’ve agreed to send me a new BMS as they concluded I did in fact connect it correctly. I/they/we could be missing something of course.
I guess I could try hooking everything up except for the P2 and see if it powers up, and then connect that protection board pin with a fuse of some kind. Any tips on what I could use there?
if you do some of the discourse bot tasks or just spend some time logged in and browsing the site you’ll quickly get upgraded to “definitely not spam” status so you can post pics and links. Just keeps the bots down by making them invest human scale time into starting an account.
Ya, means the “bms” and not some part of the bms or anything in my experience.
Ive used a current limited power supply once but if you can try it on something current limited would be better. Not sure the best practice though - if they said thet your original wiring was correct id get them to bless it first and take a video
Ok thanks, I’ll report back in a few weeks when I have a new BMS to try.
