2019 EZ Go RXV LSV

[vertigo]

I am the original owner of a 2019 RXV, LSV.
Looking for ways to make it a bit faster with more range.

Cart was built (for DOT compliance) by a company called Mid South LSV.
It is a 48 volt cart with 4, 12 volt batteries.

From what I am told, everything is original as it came from EZ Go. Motor, controller, etc, etc.
The exception is that it was programmed for a max speed on 25mph.
Cart will do 28 mph according to multiple GPS units.

My questions to the brain trust are.
If I change the wheels and tires to 23" ( with 6" lift) motor, controller and battery cables. How much more speed can I expect to gain?

Also would swapping to Lithium give me a much more noticeable range over lead acid?
The current digital battery gauge is unreliable at best.

Thanks in advance.

What controller do you 1206AC-52?? What size of tire are you running right now?

As far as I know the controller is stock as it came from EZ Go.

Wheels are 12" are I believe tires are 18".

6-8v batteries will get you more distant. 205/65-10 tires will get you more speed without lifting the cart. I would have to see your controller to be able to say if you can get more speed out of it or not.

Attached is a picture of the rear of the controller.
Hope this helps.

Tires are 214/40-12.

The 6" lift was part of the sale as I have intentions of lifting the cart.

No, that doesn't help at all. If you're going to 23" tires, you need to upgrade to a 350amp Curtis RXV controller. The 235amp controllers are over matched once you go to that big or tire.

Will upgrading to a 350 amp controller, along with lift and 23" tires increase mph?
If so, roughly what would the increase be, roughly?

[usgicollector]

With a programmed 350amp controller around 33mph maybe more...

Thanks for the insight.

Also. Will swapping the lead acid for Lithium increase range substantially or is it not worth the expense?

[Volt_Ampere]

Lithium only increases range if you have increased AH capacity. But it's worth the expense IMO for several reasons: Saves about 300 Lbs weight, no acid / water / corrosion, should last at least 10 years. The longevity makes up for the expense if you plan on keeping your rig.
