I’m hoping someone can rescue me here as I have recommended a 16s lipo setup for a friend for his ebike.
I told him to order a 45a 16s BMS and it has turned up with no instructions. Also the board itself has no markings.
My problem is that the board had 15 leads for balancing. And also another plug with 3 leads.
I’ve no idea what’s what. I thought a 16s BMS would have 17 (possibly 16 at least) balancing leads.
Do you think they have sent the wrong one?
Also, what is the 3 pin plug for?
