Why the Torque on your EZGO Golf Cart is Too Low


EZGO torque is too low

How Much Torque Does an EZGO Golf Cart Have?

The average amount of torque on a EZGO golf cart is between 19.91 – 34.5 lb-ft.

It depends on whether your EZGO golf cart is run on gas or electric power. If you consider a Villager 4 model golf cart, the electric version can crank up a torque of 34.5 lb-ft at 1,980 RPM.

The same cart running on gasoline would produce a torque of only 19.91 lb-ft @2,400 RPM. This is one of the reasons that many facilities prefer to allow electric golf carts within their premises.

The other considerations are that the gas-run carts will mean storing inflammable stuff such as fuel etc. in the club.

There are issues related to insurance as well, since the gas-run carts will end up pushing the premiums higher, looking at the risks they carry.

 

Why is the Torque on My Golf Cart Too Low?

Golf carts that have been lifted can have a low torque situation since the controller may not be able to raise the required torque.

There is a need to check the batteries and the cables to be sure what the issue is for the low torque. Here are some possible reasons:

  • In one instance, the user had lifted the cart from its18-inch wheel to a 25-inch one. This is one major reason the motor could not generate enough horsepower to turn the wheel and therefore low torque was experienced.
  • Low torque can happen even if a 500A Alltrax controller is fitted.
  • The XCT settings should be checked and programming parameters altered.
  • As mentioned, checking the battery pack is important. It is often observed that one battery in a pack may not be delivering the rated current leading to the overall pack dropping its power.
  • Check the battery charger since a low-amperage charger may result in the batteries not getting charged enough to lift the power required for full torque.
  • The motor is another area that can directly impact the ‘low torque’ situation. The motor’s RPM, the current it draws, will all have to be recorded in real-time and analyzed to know where the exact problem lies.

The ideal way is to do these checks one by one and record the findings. You can then share it with the others to come up with the real reason for the torque being low on your golf cart.

 

EZGO TXT Torque is Too Low

There are ways to improve the torque on your EZGO TXT golf cart if you don’t mind the expense involved. Here are a few things you can do:

  • Buy and fit a new Alltrax 500A controller along with the fan.
  • Install a new solenoid.
  • You can change the rotary switch for forward/reverse and fix a new heavy-duty F/R switch.
  • Go for an all-new 48 V battery pack.
  • Change the cables to suit the new 48 V pack with the appropriate lengths.
  • You have the option to change the motor but that can be left for a later day.

With all these changes, you will find the cart giving you the torque you expect. You can drive with even 4 passengers.

 

How get more Torque on EZGO TXT

Many people buy old carts and redo them. A frequently observed change that they get done is to lift the carts with 22-inch tires in place of the stock 18-inch ones. Some change the battery pack. The cart may run smoothly on a level surface if the road is well laid.

It is when trying to climb a hill or a slope that they face trouble. Either the cart stutters or they don’t feel sufficient torque even after pressing the pedal to the floor. There are a few things you can do to get more torque on your EZGO TXT golf cart.

  • Replace your stock controller (particularly if it’s DCS) to an Alltrax XCT 48400PDS controller.
  • Replace all cables to 4 gauge or even better, 2a gauge.
  • Fix a new super-duty 400A solenoid (1000A peak); it is capable of working across the power range 36 V/42 V/48 V.
  • If the current power pack in your golf cart is 36 V, you can add an extra 6 V to make it 42 V.
  • You can decide on replacing the motor after checking out how the cart runs after you have made all the above changes. If you are getting the required torque and the speed, then you may let it run for some more time before replacing it.

Don’t worry about the stock parts you are removing from your cart. You can put them up for sale on eBay.

You must be clear on the difference between speed and torque.

In simple terms, speed is the rate at which the motor delivers rotations, usually expressed as RPM or rotations per minute. Torque, on the other hand, is the force the motor generates to push a vehicle forward and is expressed in lb-ft.

Another thought on rectifying the low torque issue is the process of checking the battery power, especially if it is dropping during a climb.

The suggested course is to have a DVM connected to the battery unit at the two terminals. Charge the batteries to full and take the cart out on the climb where the low-torque issue is faced. Keep observing and noting the voltage readings on the DVM. Press the pedal to the floor.

The acceptable situation in a 36 V battery pack is that the current can drop up to 31.5 V at maximum acceleration. If you notice that the voltage indicates above this threshold, move to the next exercise.

In the next exercise, the DVM should be connected between the M- and B+ terminals of the controller. Repeat the maneuver over the same incline or slope.

The readings should match the earlier set of voltage readings. If they don’t, there could be some issues either with the cables or the controller. You can go back to the above suggestions on the replacements to get the best torque.

 

EZGO RXV Torque is Too Low

One of the reasons for the torque being low on the EZGO RXV golf carts has been attributed to the Danaher or ACO controllers. They offer very little options for programming and torque-setting is definitely missing among them.

The suggested course is to go in for a Curtis 350 Amp conversion. You will have to source it from the right seller or you will end up spending more than necessary.

Some users can get confused at times with a feature in the RXV model golf carts from EZGO. The cart will come to a halt if it finds an obstruction like a wall and the motor goes to the ‘stall’ position. This is mistaken as a low torque issue. As mentioned above, you cannot fiddle with the torque settings in an RXV.

You will have to go back to check the usual suspects – the tire size, batteries, cables, controller, and the solenoid among other things.

Many experts, after years of working on RXVs, recommend that you don’t go for lifting of the golf carts on this model. Users with complaints of low torque of their carts, especially when climbing hills, find in the end that their decision to lift their carts was wrong.

A 23-inch tire is unable to gain the same momentum as an 18-inch tire. This is one reason the torque is low and is felt clearly by the user.

 

How to Increase Torque on EZGO RXV?

There is one school of thought that completely discourages making changes to the EZGO RXV golf carts. These experts claim that with the stock parts like the tires and controller, the RXV can provide adequate speed and the required torque to climb hills without a whimper.

Others don’t mind the changes being done like lifting as long as the rest of the parameters are also attended to. One of the suggestions is to approach a dealer for using the handheld programmer to make the necessary changes in the settings.

These changes can increase the speed from an average of 15MPH to 19MPH directly.

Remember that using larger tires on your golf cart means higher speeds.

RXV’s as mentioned above, have this limitation that not many settings can be changed. There are only three-speed settings -low, medium, and high. Speeds higher than 25MPH are considered illegal as well.

For higher torques, you can take a look at the gear. The recommended gear ratio is 12.5:1.

 

RXV Torque Setting

It has already been made clear that the very design of the EZGO RXV golf carts is that there is no provision for pre-setting the torque. There is a scope to set the speed levels and that is in three slabs – low, medium, and high. Some settings can be altered if you took your cart to the nearest dealer who will use a programmer to do it.

Users are in a bit of confusion regarding the battery configuration. On a 48v RXV, should you have 6 batteries of 8 V each or 8 batteries of 6 V each?

The fact is that if you have 8 batteries instead of 6, the cart may end up with more weight. This could ultimately affect the momentum you are trying to gain with increased torque and pulling power but these options are better than the 4×12 V configuration for various technical reasons.

You can give some consideration to the battery make as well. Some brands offer better performance and a longer lifespan than others. Do a little bit of research to get this right.

Many users would go with recommendations from EZGO. Efforts are on to get Lithium batteries to run golf carts. They are much lighter and can offer better and longer performance.
