Thanks, I checked and appears there is no way to adjust controller settings other than PV off/on and load off/on. Batteries are all charged appears as you suggested that controller assumes only one battery. Hope that is the case as I am getting ready to go 300 miles in a race.

I have a a solar boat with 6 (130 watt) panels, 80 amp Chinese controller, 8 (98 amp hour) batteries(parallel) and 2 (45 lb) trolling motors. At full throttle one motor draws around 35 amps. After an hour at full throttle the controller shows the batteries at only 65%. Any thoughts?

Is it possible your controller thinks you only have 98 Amp-Hours total capacity? (8 batteries in parallel is not a very common configuration so setting up the controller incorrectly is more likely). 35 amps being drawn for an hour would leave 65% remaining if total capacity was only around 100 Amp-Hours. Can you tell the controller you recharged the batteries (without actually doing so) and see how much energy is really remaining?
