I am still a novice, had same questions, what I learned was that EZGO does not have a 48V cart (except the new RXV - which is out of my price range).

In my area, you can get a used electric for about $2500, with everything stock.

If you decide to go the 48V route, you would be looking at the following to do the upgrade:
8 Trojan T-105
48V battery charger
Alltrax controller
HD solenoid
new 4 ga cables
replacement motor
might as well replace the resistor and diode
HD bus bars for FNR switch (depending on model)

Parts are going to run at least $3000 for the above shopping list.

If you add the lift kit, big tires, back seat, and some bling to make it all come together...... well, you get the picture.


If your goal is 20 MPH, you can do that with 36V. You would need to replace the controller, solenoid, motor, and add 4 Ga wires. (Top speed is determined by your tire size.) It is quite a puzzle to get into the 20 MPH club as it requires careful matching of the above components. Most replacement motors will NOT get you to that speed range without the 48V upgrade. I called several motor suppliers and could not get above 16 MPH at 36V. One phone call to EMP fixed all that.

If the budget is 1K, you will need to stay at 36V for the present, but you can purchase a controller & motor that will work at 48V and spread the project over multiple years. To complete the upgrade later you could add a 48V solenoid and 2 batteries and a 48V charger.

Decide what performance you need and start gathering your shopping list...

Regards,
Aimless

Aimless thank you, that is what I was wanting to know, EZ-Go does not make a 48 volt cart other than RXV line. That pretty much settles it for me unfortunately. I know where to go buy a stock 2003 CC Precedent with new batteries for $2400 that will do 20 Mph with just a program change, so guess I guess I will stick with my first choice.

I did read the D392 motor with a 400 amp controler @ 36V will do 24 Mph, not sure to believe that or not, but I read it in more than one place.

Ezgo does indeed have 48v dc carts in the workhorse line that are not RXV ac carts. They have even carried over that 48v system to many of the Textron turf maintenance vehicles with 2 speed options run through power and speed rocker switches. I guess they never saw a need to put that setup in a TXT.
I don't fool with electric carts so it hasn't been a real priority for me to learn much about them.

Jon thanks for the feedback. I am aware EZ-GO makes 48 volt in the maintenance and utility lines, just for some reason I thought they might have also made it in the TXT family of products. Since the cart will be used for GOLF, donít think a utility class will do the job I want, nor do I think the course management would be happy about it either

I am disappointed because I really wanted an EZ-GO because of the availability of service, parts, and stiff competition from dealers in my area of DFW.

FWIW I did go by a dealer today and got the education I was seeking in the product lines. Looks like the TXT line has several vintages which is not made clear on EZ GO website. The TXT comes in 3 flavors over the years. The current model is the PDS system, which I am not interested in if I was going to modify. Just before the PDS was the DCS system or first generation of Regen braking. Then there is what I believe is called SERIES meaning a series wound motor and the F/R lever mechanism is on the seat between driver and passenger.

So if you guruís are still reading along I have a question about the TXT SERIES model to 48 volt conversion. When I look under the seat there appears to be enough room to install 4-12 volt batteries. Am I right or am I missing something?

The guru's will say it is not recommended to do 4 at 12V. The standard 12 battery is not constructed (internally) the same as the 6V and 8V batteries used for golf carts. The plate spacing internal to the golf cart batteries give them better run times and with proper maintenance you will also get longer lifespan in the golf cart. (Ever hear of a car battery lasting 8 years?)

OK, so can you put in 6-8 volts?

The T105 has the same physical demensions as the T890. Amp Hour ratings are different with T105 = 225, and T890 = 190, but the T890 configured at 48 volts = 9.12 Kwh storage vs 8.1 Kwh for the T105

6-8v batteries will work, but you will get better range with 8-6v batteries. If range is not an issue spend the money on the 8v cells.

Using 8v cells will force you into a 48v-12v convertor for lights and accessories however. Isn't this fun?

derekbc, 2 extra batteries are typically mounted in the bagwell and since you stated the cart will be used for golf well....where are you gonna but your clubs?
Most of the 48v carts are tuned down to the 11-14 mph course standard. So don't assume that just because it is 48v it will be fast.

A 48v cart running a 48v motor is no faster than a 36v cart running a 36v motor. Now take a 36v motor and run it on 48v, much better!
