Default 48 volt??

Reading Rogers built thread and they said that the 36 volt motor he had(it is the same one I have) could be run on 48volt. Can someone tell me what all I wouls have to do to convert my 85 EZGO to 48 volt??? I am VERY new so,Not tryin to sound demanding but I would have to have some very good and complete instructions on what to get and wiring diagrams and stuff thanks. WOW just by reading forums I have learned alot Thanks to all who have helped!!! Larry

Not too difficult, how many wires and cables on your pack positive and how many on pack negative? Do you know which wires control the solenoids when they energize?

Solenoid:
Large posts are amp carrying, motor and battery amperage go through here.
Small posts go to pull-in coil, when these posts see 36 volts the solenoid makes the connection between the large posts. This way a small current can control a large current.

When you go 48V you want to add batteries to the pack in series but you want to coil controls to stay at 36 volts. The large post will have no issue with 48 volts but the small posts at 48 volts could burn out the pull-in coil.

If your system is in good shape it will handle 48V without issue, if something is weak the increased power will finish it quickly.

You need to figure out if you have a resistor coil or a controller cart. Use the search to find lots of good info in the archives! Basically u will need:
A source of 48 volts ( add two 6v or ...)
A way to charge 48v ( search for options)
A HD Forward/ Reverse switch
A 48v solenoid ( or some fancy wiring from an advanced technician like Nate or ?)
4 gage cables
If controller cart then a 48v controller ( if your's is not 36-48v?)
Clean shorts?

You won't be disappointed raising to 48v. Lots more speed and torque and its really easy to do with a resistor cart. I ran my original 36v coil for months with no problem, but for safety its better to use a 48v solenoid.

Yes. You can run your motor on 36 volts. If your motor is in good condition it will last a long time. If it is not then it will not. Running on 48v may find the weakest link in your drive train. You do risk breaking something that otherwiswe may have lasted longer on 36 volts. Is that pretty clear? This conversion is not without risks.

I have an 89 CC. It has been on 48v for almost 1 year. Runs great. Its the ranch favorite.

I'm also in the process of upgrading to 48 volts. I can get the 8 volts for the same price as the 6volts. Why not just add 2 more 8 volt batteries in the bag well? This will give you a total of 52 volts. But how would you charge the additional 2 8 volts?
