It is just simple math but you need to know the power draw of your cart.
The latest EZGO RXV AC electric does about 2.0ah per mile. It does this with lower power output that makes it as slow as a gas cart. The less efficient AC carts are maybe 2.5ah per mile.
4 Trojan Trillium 12V lithiums are 4x110ah=48V110ah or about 110ah/2.0ah=55 miles at 80F.
Note how many electric cars you see at the side of the road because you just never know when the batteries will die - LOL
