It will come down to where you live and your requirements. IMO a good guideline is if your
daily range requirement exceeds 30-35 miles you are on the edge to needing a gas cart.
Will some battery packs go further that 35? Of course, but even the best packs should not be taken more than 40 miles
regularly.
If you go electric, be aware, battery packs matter, the more batteries in a pack the better the range, 8 6 volt batteries goes further that 6 8 volt batteries which goes further than 4 12 volt batteries.
I modified my 2002 Club Car to hold 8 6 volt batteries. I have documented this cart travelling full speed for 50 miles which brought the pack to 50%.
I did find one way to double my daily range. My wife bought a second electric cart
Hope that helps....
