I'll be following this project with a great deal of interest.
My BMS is an analogue design that does cell monitoring with low voltage output that lowers the Cougar output, a high voltage limit that forces the charger to back off & a high voltage cut that cuts off the charging if any cell goes over the max voltage. It also does bottom balancing.
Heaps of wires & heaps of connections though & no way of telling which cell triggered a fault condition.
It would be very nice to have a digital setup especially via the LCD display.
Smaller, less wires (mine was a nightmare), more diagnostic info & easily changeable parameters.
