Can a solar charge controller act as a battery monitor?

BFL, I wonder if that means the Trimetric is more accurate with higher charge rates than with lower? (because there is less heat generated at a lower rate)

Sort of. There is a discussion of that in the Trimetric's manual. They say once gassing gets really going above 80% SOC, they don't have a good handle on it, but also that isn't many of the total count from 50-100% Also that in the mid-SOCs it can be less than 4% for heat loss. So 4% is a number that works fairly well over-all.
