I recently fitted a vanbitz battery master to work in conjunction with my solar panel set-up.
The van has been parked now for about four weeks in brilliant sunshine with nothing but the alarm to use any power.
Today I did a bit of tinkering and soon noticed the engine battery was sitting at 12.2v while the hab batteries had a floating charge of about 13.4v.
Should the engine battery have more voltage than that? Curiosity got the better of me so I thought I would try to turn the green light on the B/M to red by putting a heavy load on the battery.
So without starting the engine I put the ignition on and turned on everything possible which brought the engine battery down to 11.5v, which I kept at for 5 minutes. During this time the B/M light remained green. I thought it would have picked up on the low voltage and turned red, am I missing something?
