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...

o.k., good to know (i did wonder about that)
I think I'll have to grab a couple of pigtails, and run a pair of 100w bulbs. Then I can add a 7w, 10w, and/or 15w to it if necessary. I'm guessing 200w may be a little low?
It will be a bit low if you use your Xantrex maybe. I moved my 2000w Vector inverter to the truck camper and now have a 2000w Can Tire Xantrex instead in the 5er.
The Xantrex draws fewer amps to run the toaster, kettle, or microwave than the Vector did, which was close to the divide by 10 rule. So the newer Xantrex might be more "efficient" and so 200w would be a bit low perhaps. Try it and see before your actual tests.
(One thing I don't like is the Can Tire 2000w Xantrex (was on sale for $169) has its 11v alarm spec as 11 to 11.3 ish and mine is near 11.3, which is bad when you are down in battery and want to use the toaster. OTOH the alarm is not very loud, unlike the Vector's air raid warning siren at 11v, so it is easy to ignore! :)
