Default 48v conversion question

I have a 88 ezgo freedom, can i convert to 48v(8- 6v batteries). I have done a lot of searches and not found the right info, I am new to golf carts. It is a stock cart. Can I just add the last two batteries in line. Any pics or directions would be great. Thanks Tony

It is easiest to install the two extra batteries in the bagwell and cable them up like this diagram. You will need a 48v controller, solenoid, & charger. Additionally you will need to beef up the cables and the F&R.
Search around a little lots of members have gone this route.

An 88 ezgo is a resistor coil cart, so you are looking at bringing the drive system into the 21st century. If you like the cart it can be a very good option towards making it a more serviceable unit.

Lots of members have converted Ezgo and CC from resistor coils to solid state controllers.
Heck, I did for one old customer because he was burning up a speed wiper board every year on his steep property.

Simple controller pkgs start at $424 here http://www.cartsunlimited.net/

It has 24" tires and we drive it on our farm. Not crazy steep hills but there will be some.

tony with any cart, the power system has to be able to handle the volts you put to it. you just can't put two more batteries in your cart and not expect the magic smoke to not come out from under the seat

It was good talking with you on the phone. I just want to post what we talked about for everybody who reads this.

Putting 48v in a 36v resistor cart is going to make it go faster with more torque, that is the good news. THe motor does respond well to the increase in voltage. The bad news is the speed wiper board and the resistor coils and solenoid will burn up..... just no telling when, it depends upon your usage. It may fry the solenoid on the test drive, or it may last a year and fry wide open full throttle. This can be very dangerous and we do not recommend you put 48v in a resistor coil cart.

The proper way to upgrade is to do a solid state speed control conversion. This is a safe system with all the benefits of modern speed control and updated controllers & aftermarket motors!

Happy carting
