Did not put in a bat profile or change the timeout. Just the name timeout makes me think that is likely the problem. I will read your info linked above and then ask dumb questions...

It charges to the correct voltage, but does not seem to know we are using rather large batts (260ah).

Got the charger from Kois/Morrison, so who knows...

I am guessing on the algorithm, but the one I use for my charger, is based on a 3C 1C curve. the basics is that based on the charge current it will take so long to charge a specific AH pack. the charger is only only charging for a 220AH pack (profile #5)
you would have to have the charger reprogrammed for 260AH.
