300 Amp alltrax controller/ stock motor

[rynkshermy]

I have been fixing up this 1995 medalist over the last year.... I have it running and works great on level surface. Uphills its terrible haha..... I installed a alltrax spm 48300 series controller in it because the stock controller was fried. Is there upgraded motor to buy to help this thing climb hills a little faster without getting a bigger controller???? I now have off road tires on it, but will be replacing them with street tires shortly. Any info would be greatly appreciated. Thanks in advance

Have you changed the batteries to 48 volt???? I think a 95 model were 36 volt batteries. If they have not been changed.

I didnt know I could change to 48 volt, Do I just install 6 8 volt batteries?

The controller and motor will run on 48V, but you might have to replace the solenoid unless its coil is rated for 48V.
The battery terminals on 8V batteries are both on same side, so you may also have to replace some of the high current cables the connect the batteries in series.

The off-road tires are most likely taller than 18" (stock), which is reducing the amount of torque the cart has, and limiting its ability to climb hills. Upping the pack voltage to 48V will increase both torque and speed.

I just bought 6 new 6 volt batteries sat, just called the place I bought em from and he said I can swap em out for 6 8 volts. I just want to make sure this stock motor will for sure handle 48 volts before I swap em.

The stock motor will run just fine on 48v but you will need a 48v pre-charge resistor and a 48v battery charger.

Been usi-g the world famous Stanley charger...... What's the news on them? Seem to have been charging my 36 volts fine

Does anyone know a part number for the solenoid that I need to get to fit the alltrax spm controller in order to upgrade from 36v to 48v? Does it have to be a H.D. one ? and do I have to replace FWD Reverse switch as well?

Go to Carts Unlimited, they have everything you need. And if you want to make sure that you're doing the right upgrades, just call and ask for Scottyb!

It's probably worth your while to call Scotty at Carts Unlimited (see above) to talk about the specifics and get his 48 volt charger, great price for a quality charger.
