Wow to that post count.

When you say the stock 48v controller is weak, are you talking about an anticipated longevity issue or weak as in holding the cart back from its performance potential?

With an upgraded motor, both of those things.

with the cart in my signature I hit 35mph

stopping is scary though

Well that's very cheap for a controller. Can you expand on why you recommend this one? I am guessing it's a good value. One thing I'm noticing is it wires up differently than mine.

Sounds awesome. Unfortunately in Post#19 I mentioned I am staying with a Series motor.

You will need a Curtis Hand-Held Programmer. Program the controller for 48 volts and throttle type 6 (ITS)

Red wire to J1
Black wire to J2
White wire to J3
Orange wire (half-speed reverse) to J5

Program port J4
You will need power on B+ and J1 before the programmer will turn on.

If the controller is exposed to water, you should apply extra silicone sealant around the areas where the terminals penetrate the bezel.

Okay it looks like the Curtis handheld programmer is around $500+? I don't see why this Chinese ebay controller plus a programmer would be the preferred path over just buying an Alltrax controller.

Kernal,
Fully charged my Trojan T-105 36V pack read 38.3V.

As long as that reading was taken 12 or more hours after the charger shut off It's good. Next attach the meter probes to the battery pack main + and main - and go for a ride. Note what the voltage sags to under heavy acceleration. Floor it. The voltage will come down and start to recover some slowly. We want the voltage where it bottoms out. Do this going up a hill if you have one. Hopefully not lower that about 31.5v.
Also, what are you using to measure speed? An app on the phone is fine but let the cart run some distance to get the top speed. If you can find 50-100 yards of level hard surface, pavement if possible would be good. Driver only and tires 20psi or greater.
