Question Royal Ride 48V conversion

I finally found this '89 RR. I'd been looking for this model with the bucket seats and center console along with the light colored wood dash for awhile. Apparently, this one was stored away and forgotten in some time warp. Other than one minor ding, the cart is perfect and unbelievably unused. I'm planning on restoring it to pristine condition and upgrading the details. The only issue I have atm is that it's really slow (12mph). I'm thinking that the batteries, even with a sticker date of 7/10, are bad. As soon as I put about 10-15mins of load on them, the SoC meter drops to 75%, even just after charging. My guess is that they put in cheap E used batts to get it to run.

So, given that I'm going to buy new batteries, I thought I'd upgrade to 72V. I found a big cart dealership that didn't recommend the 72V upgrade, but will convert my 36V single solenoid resistor RR to a 48V electronic controller setup for $2K. Is that a good deal? Is it DIYable? [not mech challenged]

Nonetheless, after recovering from the shock of "the best way to upgrade speed", I did some research and found that simply upgrading the batts to 8V's will be enough for me to gain 5mph without problems. I'll probably upgrade the solenoid to a HD 48V to be safe, but I'm thinking no cable upgrade. Is there a big difference between the $2K conversion versus the cheaper way?

I figured that I'll need the batts (US Battery US8VGCXC) either way and with only the added cost of a single solenoid, I can always go the route of the $2K setup if there's enough of a difference. I really hate other carts whizzing by me ...lol.

An odd side note...Why would this cart have such weird torque with bad batteries? On a floored take off you hear this bang like popping a clutch and the cart shakes as it lays a little rubber with the front end feeling like it's going to pop a wheelie...then tops out at 12mph..rofl.

Thanks in advance.

Your drive system is a resistor coil speed control. If you put 48v in the cart without a full upgrade to Solid State you will melt something and possibly burn that cart to the ground.

It is a very DIY-able project many here have made the advancement. If you plan on keeping the cart and don't mind turning wrenches and can make up a little linkage modification, you can save yourself 5-750 dollars.

Post pictures from under the seat, please.

In the bottom of the picture is a row of resistor coils, they will not handle 48v nor will the Vglide set up you have in a pie shaped box bolted to the frame beneath the drivers seat.

You need to make a full conversion or leave it as is

yes do the upgrade but get the parts other than a dealer you,ll save some cash......you,ll need a 48 volt soleniod, controller, hd F&R switch, potbox cables and your batteries and a way to charge them...........now depending on how much you want to upgrade you can go to 72 volts....thats all up to you but with the resistor coils and V-glide they arn,t gonna cut it..............................
