Dropping voltage on starter battery

Postby HansR on Wed Dec 01, 2010 4:36 pm

I have been having troubles with my new house batteries. I have been suspecting that the batteries are the problem.
I have now noticed that the starter battery is dropping voltage nearly (but not as steep) in line with the house batteries.
Could this indicate a problem with the control panel.
I have a SARv3 regulator on an Ample Power control panel plus an EMon. Batteries are 3 banks of 2 T145's and a truck starter battery also new.

Could you offer any advice ?

Have you measured current draw from the batteries?

What happens if you disconnect the batteries?
