Ezgo series 36v adding Alltrax Spm controller

[fireboat]

I have a 92 Marathon that I just fully restored, that only did 12.8mph originally. I lifted the cart and put 22-inch wheels on which bumped the speed up to 15 but it had no torque.
I did the PlumQuick Bandit motor upgrade along with a 500amp controller, solenoid, and HD F/R switch from Scotty's plus 2ga cables. I now roll at a solid 19+mph with much more torque, I am very happy with the upgrades. I don't think the PlumQuick motor is soley responsible for the 4mph increase, I'm sure the greater amp capacity helped too. Now I'm looking forward to seeing what 48v will do.

I think I'll go with the 500 and save the custom mount and $200!!!

The controller didn't make your cart faster at all since it's a series cart. The lager tires provided the 4 mph increase.

Controller may, I say May, make it a little faster because it can supply enough current. The original May mot have been angle to get to full speed.

I agree, but we are talking maybe 2 mph, if the old controller really sucked.

A higher amp controller will help climb hills faster, and may help overcome rolling resistance, but everything else stated above is true. For a series, more voltage, larger tires, faster motor, and gears are the way to gain speed. A beefier controller will offset the loss in torque that each (besides the voltage increase) will cause.

I don't know if your up for it but I found a alltrax spm-48400 for 200 bucks new... I went a head and bought one. seems like a awesome deal

Not bad at all

Hey guys, I didn't mean to imply my new 500amp controller was responsible for a significant portion of the 4mph increase though I think it helped slightly.
I think really it was mostly a combination of the PlumQuick motor and the 2ga cables. I think my old 6ga wires were in bad shape and the motor just wasn't getting enough amperage to overcome normal rolling resistance because 15mph (actually I think it was just over 14 if I recall correctly) was the best I got on level ground with the bigger tires. I had installed the 22" wheels previous to the electrical upgrades.
As expected, the torque increase has been by far the biggest improvement with the new controller, wires, solenoid and HD F/R switch. I can carry four people around with no effort at all.
My apologies to the OP, didn't mean to hijack the thread.
