New BMS installed and working

The new BMS (minibms from Clean Auto LLC) was actually easy to install and understand.  Only one minor complaint – the high-voltage alarm turns on if one of the cells triggers an alert – can be annoying to my neighbor as the car is parked next to his bedroom.  I’ll add a relay to cut off the audible alarm.

So picture time.  Here are the before pictures.

And here are the after pictures.  Much nicer, no?

The light is a repurposed CAT warning light – I’ll be adding a label to it later. Note that there is also a high-low tone buzzer just under the dash.
