locking for cheap configurable BMS for extended e-bike battery

Hi,

Until I have enough Cells to build my own Powerwall I'm using temporay 3 times 36V e-bike batteries that I extended to 48V.
To not destroy them when they are in use I need some kind of BMS that is configurable to use the Batteries only between 4.0V and 3.5V.
I already tested the smart BMS that Daromer used for a 1kWh Pack, but would need three of this type for my 3 Batteries
and 50 each is to expensive from my point of view.

So does anybody know a cheap confgurable BMS that I can add to each 48V Module and set it between 3.5v and 4V?

Use One of them and Connect the batteries to 1.

Hi daromer,

yes that is what I also thought, after asking this question, thanks for supporting me to that solution.
I will try to build some kind of a bus connector to parallel connect all e-bike Batteries I have that way....
