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...

Several hours "past full" in daily format at 14.6 is too much in my opinion. i forgot what batteries you are using, but this is an early demise formula for 5% antimony batteries. Antimony poisoning. Wouldn't matter if it were infrequent but on a daily basis this becomes a definite concern.
On eBay you will find interval 7-day 12-volt timers. Their quiescent power requirement is impressively minimal. By coupling the timer to a simple to connect 40-amp solid state DC/DC relay (cheap!) you can control an impressive load or charging source. Set the off time, say, at 1430 hours, and enable time at 0700 and you have a hand's off timer circuit.
Connection, and operation of the timer and SS relay is a piece of cake. Both are reliable and the SS relay uses MOSFET transistors with voltage drop measured in millivolts.
