So MW, what is your take? To slap up a HV charge for 4 hours during the boost cycle? How high do you go, assuming you have a lot of experience in burning these GC2s out. I don't have a problem installing a boost button but again, what's going to happen to all my appliances (frig controller, etc) when it gets a big bump like that - do I disconnect the battery from the house while applying the 15+ volts? I looked for some time and didn't see a variable V 60A supply for sale just now, a lot of 5V models but I didn't see a variable volt. Mouser would do so much better if they would ever come up with a readable catalog. Anyway, Thanks!
