i need new coach batteries and wondered what kind i should purchase. at present have 2 12v interstates but very unhappy with their performance thankyou in advance hb          ive been told that 6v performs better than 12v. are there any changes to hooking up 6v over 12v? ty   hb
Often when batteries fail to perform as expected it is the charging system not the battery.
Might be time to update the converter or better yet get some (200w+) solar.
Otherwise no changes needed to go 12v in parallel to a pair of 6v in series.
This thread is a bit dated.  Is HB still around?
