Adding more batteries
Good Afternoon all! Fully charged my 2 x 6v batteries in my class A work well and provide me 208AH (104 usable). I have 300 watts of solar that works great in the summer to keep me going however in...

So I bought a 75 amp boondocker drop-in for the 55 Amp WFCO that came with my trailer. It's been working fantastic, goes immediately to 75 amps and holds the voltage fine till almost fully charged with peak voltage at 14.6 and only 180AH of AGM battery it gets there pretty fast: now the 'but'.
I've had a couple people now tell me the Boondockers taper the voltage way too soon, so I'm reviewing threads to find people who have had problems to find out what's different that breaks it sonetimes. Hi there to this thread, ?? I'm going to increase the battery capacity and I'm nervous I'll break something if there is an inherent weakness somewhere so I'm trying to to father more data.
1)I notice most people in these threads are using flooded cell golf cart batteries. Is anyone using AGM batteries and still seeing early drop off boost?
2)I moved my batteries so they are like 2 feet from the converter as part of my upgrade. I see in some of these threads that less resistance is seen to lessen the problem of early dropout. I tried an experiment of moving the battery back to the front, so like 15? foot of #6. Of course the current is less and the charging takes longer, but it still seems to be doing what it can within its limits of a maximum of 14.6 volts. It loses a maximum of 0.4 volts in line loses early in the charging cycle, but holds maximum voltage well.
The reason I am interested is that there is not enough room near the convertor for the total battery capacity I want and I'm nervous when I move things the approximate 8 foot of wire will expose some weakness and I'll have to plan on more work than just moving the batteries. I'm lazy btw.
Any more detailed insight, or other thread links, appreciated on what specifically the problem is triggered by. I'm not interested in changing the converter, please no product placements.
