I don't care for the multiple battery banks either but due to the physical locations of the banks (opposite sides of the boat) I decided to separate them.
Yes, I can isolate, or combine, each bank.
Looks like its time to buy a real battery monitor system to see actual charge current.
FWIW: The last time I charged the batteries, I tried running one circuit only and hooking it directly to a very low battery (the refer battery after using it all day). I hooked to it with #6 wire positive (6 feet) and #8 neg (8 feet) directly. I had the temp sensor on the battery in 80 deg heat.
I still saw only 20 amps charge indicated on the charger. (wish I had a real ammeter)
I think I'll be calling Xantrex support.
