I don't really get the application case of this for the price. It seems to operate on a single cell - I don't see any coordination with other cells in series - e.g. "Balance Board" in the product listing title seems out of place since you don't balance a single 18650 cell.

Because its made for 1s. You should have for 14s IF thats what you go for.

You would need 1400 of above for 14s80p.... Cheaper and better to get a proper system

If you plan running 120p then sure.. But not for anything else. A 1s bms cannot sense overal package voltage or current. And therefore you will get cascading strange effects.
Its also just expensive doing so.

Im sorry but I only see it as a waste of time and money.
15A is also to much for 1 cell... It should be 2A or something

Why did you ask for advice and still you did not follow the advice?
