Ok - so this is what I was thinking. I thought my breakers were rated for much more current, but it looks like they are only rated for 5A (both AC [1] and BATT [2]).
In short - I need a breaker that can handle more current, correct? I have these breakers at a ton of sites.. can't believe I just noticed they were only rated for 5A. :( In the meantime, I may need to use an external charger to get these batteries charged back up.
