That is a lot of work.. Modern Converters also use switched power supplies, do all the adjustments needed (Bulk/Absorption/Float and sometimes equalization) automatically. And work well, Progressive dynamics 9200 line for example.
Of course yours is 5-8 ampers, A nice SLOW charge as suggested by Trojan. Where as my PDI is 80 amps peak. Much better for boondocking when I need a fast charge before quite hours come about.
How much ampere hours of 12v battery pack do you need to recharge? You push 15.0V into a set of T-6 220Ah batteries, and one of these will start out pushing 36 aH. Two of them, 72aH. The effectiveness of bulk charging at constant voltage and the power supply unit pushing it at what ever amps the battery set will take becomes the limiting factor. I am pretty sure that when you are pushing 15.0V into a 12V system, charging time, if you have the amps to back it, are going to be minimized. This is a dry campers/boondockers dream setup.
What I don't know is how much or if battery life will be shortened or lengthened. MexWanderer can probably supply an educated guess, while charging with these power supply units.
