Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

IMO move the controller farther away from the batteries to where it is easy to keep it cool. Never mind the additional line loss if any (just use fatter wire if practicable)
I figure you will lose less by that additional line loss than by having such a hot controller with that reduction in efficiency, especially when you need cooling fans for it (that might not do much good with a "closed box" controller to cool its insides) subtracting from gains too. Controller life might be shortened too if hot at lot?
The batteries will still get charged up even with the controller farther away. If it takes a bit longer to charge them up, that helps with your concern over too long at Vabs before dark too.
