Converter vs Battery charger
In this corner we have the Progressive Dynamics 55 amp PD4655 weighing in at 10 lbs, running through 15 feet of 4 gauge cable. The owners manual said that the PD's boost feature should only be used to...

I agree. That's why I like the Quick Charge. Flip the switch on and forget it. But now that I'm getting a Mega watt what will I need to do? I have 10 gauge wire run to the batteries. About four feet total.
Do you start out with the mega watt at 15v? What do you suggest?
First off, I suggest 8 gauge wire, minimum, for the 40 amp unit (36, actually, if you read the fine print.)
Here is what I would do, if I was you.... set your voltage at 14.8V, for the first go round of full charge, or as close as you are going to get to it. Charge for 2 hours and then Measure your Specific Gravity. Are you at or above 1.275 in all your cells? Test them all. If not, have a go for another 30 minutes, and read again. Did your SG come up at all, on any cells?
Run through 3 cycles like this, normal daily discharge, charge. Check your SG after a full 14.8V charge. Still below 1.275? Bump your voltage up to 15.0V and then retest your specific gravity. Did it go up some? All cells now 1.275? Or 1.280? Maybe 1.285?
