I agree if the pm4b would hold the 14.6 for one extra hour it would be far better.
And continuing to charge at 13.6 is painfully slow. This is why I do not recommend PM for serious boondockers. Maybe with some solar to finish the last 15/20%.
i agree as well. i see no reason why the pm4b couldn't be made to sustain 14.6v for a preset interval of, say, one hour, other than maybe a cost/price issue. they've told me they were trying to keep the cost down, and bells and whistles can get expensive. but i know i'd gladly pay the extra. and that extra hour would greatly reduce the overall charge time, i would think.
Yes it does reduce the charge time by hours. But the PowerMax guys have to stay in business and they make converters not fast chargers.
You can modify yours by drilling out the four rivets of the cover, remove that, put your voltmeter into the DC output terminals, and tweak the little blue pot's screw with a glasses frame sized screwdriver, and set the voltage to say, 14.6.
Not too clear if you crank it back to 13.6 it will still work as a 4 stager. Might not. I don't care with mine. Also forget the warranty :)
