Upgrade FAQs

Q. Hi i have a 2006 ezgo txt series drive. 36v. I was wondering what I can do to make is faster? Please help! Thanks!

​A. 
The lack of speed is the biggest complaint we get about series drive carts. The best bang for your buck is increasing operating voltage to 48v. To do this upgrade the controller & solenoid must be 48v compatible and the F&R and high amperage cable set should be upgraded. 48v chargers are available with the D plug to fit your cart. Speed will increase by 33%. The addition of taller tires can raise the increase by another 20-25%
I hope this helps.

Q. What is a float charge? Do I need one? 

​A.  Float charging is a feature common to modern chargers. A float charge is a constant low amperage input which maintains the battery at a slightly elevated state of charge. This elevated state prevents loss of charge while inactive by self discharge. Self discharge can cause lead plate sulfation and chemical separation leading to reduced capacity and battery performance.  

Float charging will prevent freezing and long term storage damage due to self discharge which can be as high as 1% per day.

Q. My charger is going way above 36 or 48 volts. Should I stop it?

​A. 
Batteries charge to a level above 36 or 48 volts. This level called the cut off level varies by brand but generally is between 2.4 and 2.7 volts per cel (vpc) Mathematically this puts the cut off for 36v chargers between 44 and 48 volts. 

And for 48v chargers between 58 and 65 volts
I hope this helps.

Q.  Question about shut down

My 2005 EZGO PDS will shut down on me after it has been running awhile.  You let it sit for a bit and then it will run for a little while before shutting down again.  It seems like the speed controller is the problem.  My motor is stock and my cart is a 36volt.  I don’t live in a place with many hills, however I would like to be able to get off a paved surface and cruise around.

 What controller/ solenoid do you recommend?
Should I replace my motor too?

Do I need to convert the cart to 48 volt to get longer run times?

Hi Clay
You are describing the controller going into thermal shutdown until it cools and goes again. This is a typical failure which increases in frequency until it does not come back on.

Use the Alltrax XCT400PDS controller and 200a HD solenoid to remedy the problem. For longer run times this motor handles 42v much better than 48v. You can make a 42v pack by adding a 7th 6v battery in the space under the driver's seat. We have 42v chargers from DPI with the plug to fit your cart.
If you do just the control and solenoid the cart will gain 35% in power and reach 23mph top speed.
With the added battery you will gain 50% more power (torque) and reach 26.5 mph
I hope this helps

Q.  Will installing a bigger controller reduce the carts run-time? 

​A.  If the cart has a nice strong battery pack there is no reason to lose any range at all. A bigger speed controller allows the motor greater access to the battery pack. A lead foot driver may use the battery supply quicker with a bigger controller with hard starts. But during normal use the motor will still use the same amount of current as before to keep the armature spinning. With an older battery pack, allowing big amp draw frequently could reduce the range between recharging

Q. Can anybody do these upgrades? 

​A. Honestly, no.  Not any more than anybody can change the oil in their lawnmower. Or add a light fixture in the garage.

Modifying an electric golf cart takes a some skills and tools usually acquired by experience in similar fields.

I have created a difficulty rating system 1-4 which allows the customer to judge which projects are best suited for their skills. See install ratings 1-4.  ​
