PWM controller with no float
OK, I have a Morningstar Sunsaver 20a PWM controller. It's not the current generation, which is a 3-stage unit. It's basically a 2-stage without the float stage. It delivers full amps till the targ...

With AGMs, there is no water loss at these values due to the built in valves.
Yeah, where is Jim? I sent off a PM to him a couple of weeks ago and haven't heard back. I also liked his experiments.
Yes, AGM VRLA batteries are very tolerant but you don't want to float them so high that the valves are constantly opening. If the valves open, you are losing the oxygen and hydrogen that recombines to form the electrolyte.
