Unfortunately, it would appear I need to replace my battery bank (ouch!). I have sourced a Chinese brand 12v 120ah from Fullriver and another, an USA brand 12v 110ah from Power-sonic (yes American). Is there anyone using either of these brands since I would be looking at replacing eight of them which are my main 24v supply. I don't seem to be having a problem with the ninth that supplies my 12v supply.
