@wariat777 Hey, just looking through the posts and this is the only thing I could find online that was remotely close to what I was looking for.
I have an old Magneto electric longboard (china clone) and it looks identical to the backfire one you have listed above. You wouldn’t happen to have a picture of your new bms wired up? I would be forever grateful knowing I could buy this thing and it would actually work.
A little detail on my problem:
I have two units and one of the BMS’s was working up until today when I accidentally fried it(or at least I think it is fried)
on one of the setups, my system will turn on when connected to the charger and will run normally. When I unplug it will stay on for about 5 seconds then turn off. It will not charge or discharge on its own.
on the second skate, the battery will charge but not discharge.
I have connected both esc to the one that turns on when connected to a charger and they both work fine. I think I just damaged both BMS when I was trying to find out why they wouldn’t turn on.
I’ve attached a photo of the BMS that i need (this is the one that charges but does not discharge )
