Gene there's a second part of that questions which needs to be included.

Two batteries weigh about 130lbs, extra cables and battery brackets weigh I guess 20-30 lbs, call it 150 for sake of discussion.

So the extra batteries will give more amps = distance but it will be diminished by the extra weight.

A club cart is about 500 lbs add the extra batteries so it's now 650 lbs.

that really hurts going up the small hills & tunnels.

Now the cost to add the batteries & cables $225-$250
cost to fabricate the bracket?????

Maintain more batteries

I know I'm bias, but the solar option blows this idea away in many other ways.
