36v ? Pretty easy cart to upgrade.
Use XCT400PDS controller and 400 solenoid for 30-40% increase in torque and speeds up to 22-24 mph
You can also increase operating voltage to further boost torque and speed. Adding a 7th 6v battery will give 42v operation and a 17% increase in torque in addition to the initial increase mentioned.

I see, you complained about what I see as stock performance so I suggested an upgrade.... I'm sorry if that was not what you were looking for.
Other members will be along to help also.

Meanwhile you can attach a voltage meter to the battery pack mains - note the pack voltage at a standstill then floor the cart uphill and note the voltage when the cart is under performing ... report those 2 numbers so we can get some idea about the battery pack strength.

Do you have bigger tires? Rear seat?

Starting voltage at battery post=37.8
Going uphill voltage at battery post=28.5

Going up hill at controller:
A1/B+=9 volts
B-/B+ =28

Level Ground
Speed 14 to 15
A1/B+ =28.2
B-/B+=28.5

10 volt drop is more than I like to see in 36v pack. 37 is not a full pack to start the test.
Recharge and let the cart sit and the batteries settle for 12 hours.
Then give the test results again.
