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.
