Interstate 12volt golf cart battery

Using AH vs RC, but same idea. That 150AH batt (looks like a Trojan ) is less than two 31s at say 100AH each. Two of those 150s would be more than the two 31s

Here is the T-1275. Some Interstate 6s are made by Trojan too, according to an Interstate guy locally. That is the 225AH and the 210AH one, not the 232AH ones.
