Club Car DS Build Question, Speed & Torque

[sand dune coon]

I have a question on the build I completed last year.

It's a club car DS series cart with the following.

Alltrax sr48500
V-Glide with resistors 5k-0 ohms zero ohms at full throttle
MOT-A1
2G big wires
Newish US Batteries

6" lift with 22" tall tires.

for example, is it normal to drop down to 11 mph on a 17% grade with 1 person in the cart?? shouldn't the MOT-A1 motor speed thing up some? my same 36v motor ran the same speed.
i want to put a rear seat on it but not sure if its worth doing as i do have a couple decent hill in the neighborhood that are unavoidable..

thank you in advance.

I had a similar built series cart in Georgia with the same mot-a1 and a sr48400. Mine was a bit newer and had mcor4 but largely the same. Lifted, 23” tires. Speed was great in the flat pavement, 25+ (with 25” tires it would touch 30). But on a big hill it would drop down to 17-18mph and then run back up to 25ish once I got to the top.

It seems to be the nature of the series drive system. Sepex is a lot better at maintaining speed up a hill. But only thing I could think to check is make sure your FNR is in good shape and if it’s worn maybe get a HD FNR

Series motors make the most torque at 0 rpm, and it only goes down from there.
The nature of the beast is for the motor to have to slow down on a hill. A true Torque wind motor would probably get you another couple three mph, but it's still going to behave mostly the same on steep hills.

A sepex conversion might get you a bit better maintained speed going up hill, but that would mean redoing the entire thing again and then some because you would need the harness for the sepex controller as well. Might consider selling it and picking up an IQ cart to build, then you could use the money you made off the sale to build the new one to the max.

thanks dudes, its a brand new HD FNR unit from scotty b ,
it is what it is but, i ask question like this because i hear thing like cp241 and how he would only drop to 17-18 on hill, i dont know what the hills are like in Michigan, probably nothing like mine in the sierras..

just want to make sure i dont need to modify the map im running, is it possible to give it more torque?
