i mean at every cell.... for example ... if i have to use 80 cells ... i use 80 1s mbs
 
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
 
i just order .... 120 bms boards ....from ebay.... 1s ...6mos 15ampere...........lets see if i am corect . :)
 
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?

it is not for power wall.....iit is for ebike .... i like to experiment . :). thank you for your advice
 
Experiement is fine but this is not really an experiment. The facts on how it will work is already known and best way out is to use a proper BMS.

With that said 1s can and will work partly
