SR48500 in 2001 Club Car DS Still Slow on Hills

[barlowchiro]

I have the AllTrax SR500 controller, D&D 4:2A motor (supposed to be their torque motor) with upgraded 500A solenoid, HD F/R switch, and 2 gauge cables. Brand new Trojan T875 batteries. 6" AllSports A Arm lift with 23" tires on 10" wheels. All this is installed in my 2001 Club Car DS.

I get about 17-18 on flat ground, but it loses a good amount of speed on the hills in western Pa (down to 10-11mph). Is this controller programable?

Anything else I should check? I thought with this setup I would maintain a little more speed going up and down these hills.

I have the same question, I'm getting 12-13 on the flats and 8 mph on hills, but I have stock tires so that would put me in the same ball park as you. I was questioning the F/R switch or motor but you replaced both, so now I'm thinking it is what it is until I upgrade the motor???? We'll see what the all knowing has to say.

Well I upgraded to D&D torque motor and am having these issues. I don't know if I need to check the programming on the controller or if it could be something else. Maybe it is what it is and I'm just gonna have to get used to going much slower up hills...

Just took it for a ride. It was 18mph on flat ground, 10mph up the hill pack voltage was 43.8

That pack voltage is low unless that is a steep incline...

What you need is a horsepower motor. It's not clear what motor you got now except it's a D&D.

I was pretty steep but not uncommon in Western Pa

D&D said it was their "torque" motor. Model 170-004-0002A, which according to their website is only 8hp. That seems awfully low on the hp scale.

From D&D "Definitely the 4:2A. It has more steel and copper. The maximum torque and the lowest current draw. Better range and battery life. Speed 17 mph with 22” tires"

The motor is rated at 10.2 HP Peak @ 3470 rpm. They claim it should only go 15 mph on a flat paved surface w/big tires. I would think you need a motor that produces its max hp at about 55-6000 rpm's. What you have now is more of a hunting buggy.

That’s what I built it for, I just figured it would do better than 10mph going up a hill.
