"Best" and "Cheapest" are typically at odds with each other. :-)
Derek Barger (HighTechSystems) sells all sorts of BMS. Worth checking out.
http://www.hightechsystemsllc.com
Send Derek an email: de...@hightechsystemsllc.com
Rich Rudman (Manzanita Micro) also has been selling BMS to the
hobbyist, probably longer than anyone I can think of. (Since 1995 as I recall).

Davide' Andreas (Elithion) also sells BMS, but they typically sell to
hobbyists through retail dealers.

I have owned systems from all of these folks. Each system has its
unique advantages and disadvantages. They all work equally well, but
they all have a slightly different approach and perspective. Pick
which one suits your specific needs the best.
If you are drag racing or the like, I'd lean towards Derek.
If you need step-by-step installation instructions, Rich probably has
the easiest to follow instructions.
If you love all the bells and whistles, Davide' is a good match for you.

Hi Guys,
I blew my BMS today. Feels like an EV rite of passage.
It was a proprietary system from an older EV conversion by a now defunct UK
company so I have no way of discovering what's going on inside, I have been
unable to find any documentation.
My system is 84V from 25 Thundersky 160Ah batteries. I have a Curtis 1238
Controller.
Does anyone have any suggestions for a BMS?
I've only managed to find Orion and Elithion that look convincing.
Many thanks,
Matthew
