My question is what would be better: upgrade to 3 group 31 12v batteries or replace them with 4 gold cart batteries? (I only have space for 4)
Well 4 t-105 batteries (golf cart type) wired would give you 450 amp hours
3 group 31 deep cycle batteries would give you about 345 amp hours
If you can fit 4 of the group 31 batteries instead of 3 - you can get 460 amp hours.
If you go with AGM type batteries, it may help with fitting them in your space, since they
can be mounted at any angle without worry of spilling. The AGM type is completely sealed.
