I used Battery Boys to add 4 Relion 48v 30 aHr (120 total) lithium batteries to a 2017 Ezgo RXV cart. Drop in design. $1265 per battery. New charger $400. Dash state of charge qauge $125
External wake up switch $25
Cart runs 40 miles before reaching the recommeded do not go below 20% state of charge limit. 7 year full warranty.
Each battery has its own onboard computer monitoring system that is also linked to the other batteries. This ensures equal charging and shuts down a battery if a problem is detected. That is a great safety feature vs all the stories of lithium
batteries catching on fire. It also allows you to drive home should one battery fail. I have had no issues. The batties can be charged and unplugged at any time, unlike lead acid types. They charge in less than half the time of the lead acid types. No more adding water or cleaning battery posts. If the cart sits for three days the batteries go into sleep mode. The optional wake up switch allows you to reset without lifting the seat up to push the individual battery wake up buttons. Lithium batteries loose about 3% of their charge capacity per year. So after 7 years you will be at 80% of the initial 40 mile range. Call it 32 miles.
Most of the large single lithium battery models require modification to the carts battery tray. They have a higher aHr rating which should mean greater range. The elite version of the RXV has a 120 aHr single battery which people are reporting has the same 40 mile range.
If you feel you might need greater range you can add up to two more batteries in the standard cart battery tray up to two years from the original install date.
Other aftermarket companies offer single 48v lithium batteries that have a higher aHr rating. They sell for less but could require having your cart battery tray replaced. I selected Relion for their advanced battery monitoring system and ease of install. Battery Boys did a great job.
