Depending on how you use the golf cart will depend on which size battery would be bested suited.

The 48v 80ah and 48v 105ah are the same size as 2 lead acid batteries that are currently in your cart. Freeing up 4 batteries of space.

The 48v 80ah is designed to provide the same amount of driving distance as a new set of new lead acid quality batteries (trojan). Most people generally achieve around 2 rounds of golf (36holes)from a 48v 80ah lithium battery and is the most common purchased. The 48v 105ah is designed to customers play 2 rounds per day and using the golf cart to travel to and from the golf course in a golf course estate.

We also sell fast chargers that fully recharger the 80ah is 4-5 hrs and the 105ah in 5-6 hrs. And putting the charger on for a few hours when the cart is not being used doesn’t damage the battery at all, in fact top up chargers increase the life of the lithium battery.

Warranty is 5 years full replacement. Actual life span is 3000 -5000 cycles ( full charge and full discharger = 1 cycle). The Lithium batteries will remain at the same capacity as they were when they were new and after 5000 cycles drop to around 80% capacity.

Other advantages
Light weight reducing the wear and tear of the carts tyres, suspension bearing and brakes.
Faster and more responsive both on normal level ground and high climbing.
In built Bluetooth that allows fully monitoring of the battery and the ability to turn off the battery for great security.
Fast charging
Maintenance free. No watering systems, no leaking acid that damages golf cart frames and floors.
Long life.

If you would like more information, please let me know. To better understand the requirements , let me know the make and model, how the golf cart is used. Capacity various from the type of golf course (hilly or long distance) how each player plays. I zig zag across the fairway so I consume more power on a course than most (bad player).
