I want to connect a couple of digital volt monitor/meters (~$3.00 ea.)
...to monitor the balance of my "new" Volt battery
(going digital, NO idiot lights)

Their real simple, just (2) wires a positive (+) & a negative (-)
...& draw their power (<23mA) right from the voltage source
So, to hook up the left 1/2 pack voltage monitor
I would connect
The negative (-) lead (black wire) coming from the meter
...to the BMS pin #2 negative (-) (black wire with a purple stripe)
The positive (+) lead (red wire) coming from the meter
...to BMS pin #5 (23V) (green wire)
To hook up the right 1/2 pack voltage monitor
I would connect
The negative (-) lead (black wire) coming from the meter
...to the BMS pin # 5 (23V) (green wire)
The positive (+) lead (red wire) coming from the meter
...to BMS pin # 8 (45.9V) (dark gray wire)
