Odd or Even Battery Strings
I have a quick question about battery banks wired in series/ parallel. I currently have a 24V 440AH battery bank consisting of 8 Deka 6V 220AH batteries. I need to up my AH to at least 660 to cover my projected loads. My brother-in-law remembers reading somewhere that charge controllers like even numbers vs odd. So I'm wondering if adding another string of 4 batteries will be fine or should I add 8 to keep an even number of strings.
