Hi there, i would like to add a battery monitor to my 48v battery bank (of 24x 2v traction batteries).
It means that i want to measure voltage and temp of each cell, i can't find any commercial available product.
Any one knows a product to do this  ? 

Requirements are:
24x2v  bank 
modbus connection for scada integration.

Thanks for the help

I've had a bit of a look and I can't see anything immediately obvious either.

Thoughts are: Repurpose a BMS such as those used for ebikes.

Build your own with an arduino or similar (not complicated but fairly time consuming)

Yes that were also my options (arduino way) i already some "complex to me" projects with arduino, but i want something more "robust".
i know that upp's can have that cell control module but normally the the brain is the ups itself Sad
have to check the ebikes

PS:thanks for your answer
