36/48 volt solenoid

[LeonLem1]

Does anyone make a heavy duty solenoid that can run on 36 volt now and on 48 volt later. I am upgrading my cart in stages, and I hate to buy a 36 volt now and in a year, buy another one for a 48 volt system.

I have a 2006 EZ-Go series cart and I sent my motor to Plum Quick to be rewound for higher torque. I am putting a new set of 4 gauge wires, changing out the forward/reverse switch for a heavy duty reversing contactor, and I already have an Alltrax 400 amp AXE controller. My T-105 batteries are only about two years old, and they are in pretty good shape. I was thinking that I will upgrade to 48V when I need to replace the batteries, or in another year.

If there is a solenoid out there that can run on either voltage, I would put that in now, so in the future, I will just have to change batteries and the charger to go to 48V

Look toward the bottom of the page. Pick the super duty 400amp. It runs on 36 or 48 volts. That's the one I have and it has worked great so far. Have used it on both voltages.

Thanks! I just ordered the Super duty solenoid from Scotty B, along with the cable set and the super duty reversing contactor. Hopefully these upgrades along with my new motor, will make a noticeable difference in performance.

Dang! Scotty you owe me one!

With a high torque motor, AXE400 controller, 4Ga cables throughout, Super-Duty solenoid and a reversing contactor system, it will have better acceleration and won't slow as much going uphill, but the top speed will be about the same until you go to 48V, unless the old cables, F/R switch. solenoid and controller were in really bad shape.

When you go to 48V, you'll also get more torque along with more speed.

Scotty probably told you, but when you switch to 48v, you'll need to change the resistor on the solenoid.

That makes sense. I have a feeling that once I drive it a bit, and see the small gains that I get by doing the above mentioned upgrades, I will be chomping at the bit to make the jump to 48V! I just have to spread the financial pain out a little bit!
I was reading the specs on your setup and noticed that you are running a 42V system. What charger do you use for that?

I've got a sizable chunk of change invested in my battery pack, so I use the best portable charger out there, which happens to also be the best bang for the buck.

The 42V version has the same step-down transformer as the 48V version, so all I have to do if I decide to go to 48V at a later date, is replace the PC Board.

If you decide to go the on-board charger route, the best on-board charger is the Quick Charge, but they cost more.

Both types go into float charge after the regular charge cycle completes, which is a good feature for long term storage and even if you don't use your cart daily, you always start your trips with a fully charged battery pack.

Basically, the DPI charger is plugged into our cart whenever we're not driving it. Since battery life expectancy is primarily based on the average Soc (State of Charge), my cart batteries may last longer than I will (I turn 71 tomorrow).

So how hard is it and what does it cost to change the pc board in the charger? I am curious because I may be interested in changing to 42v now. I could buy one used 6 volt T-105 and add it to my battery pack and buy a charger. That would get me a little more power for now, until I need to replace my batteries, at which time I could make the decision to go with 6-8volts or 8-6 volts to make the change to 48. The only other thing that I would need to do is change the pc board. Is that correct?
