Recommended upgrade path for 36V Ezgo
I have an '02 36V ezgo txt series golf cart that I want to make go faster. It seems like there are 3 upgrade paths I can take, which would you recommend?
1. Remain at 36V. Upgrade the motor to a plum quick cobra (13HP) series motor and SR500 controller. Cost is ~2K. 2. Same as above, but upgrade to 10HP admiral sepex motor. Cost is about the same. 3. Throw 2 more 6V batteries in the cart and buy a 48V charger. Upgrade to 5kW AC. Cost is ~3K. In the future I will probably upgrade to 48V Lithium, but for right now I just want to stick with perfectly fine 6V trojan batteries already in the cart. I just want a golf cart that can go 25MPH carrying 4 adults on a flat road for a maximum of 10 miles between charges. Which would you choose? |

Re: Recommended upgrade path for 36V Ezgo
If you are considering lithium and upgrading to 48v would make more sense to just do that now then add more FLA to get to 48v and get a new charger since if you did go lithium you would need another new charger then too.

That's why I'm leaning towards the series or the sepex options because they can both run at 36V. But if an AC motor is the only way I'm going to be able to haul 4 adults 10 miles at 25 MPH then I'm willing to bite the bullet. |

48V and Lithium without AC or a different motor I don't think will get you to 25mph with 4 people on it. |

Re: Recommended upgrade path for 36V Ezgo
Look at the TXT48 Sepex conversion from cartsunlimited.net for this cart. This kit will run on 36v lead acid now and 48v later. The kit includes everything you need. A wire harness, Admiral motor, Alltrax control, dual voltage solenoid, Rocker switch F&R and housing, in-dash digital battery meter.
The cost is about the same $2k here > https://www.cartsunlimited.net/txt48-conversion.html |

Whereas, with option 1 or 2, I should be getting pretty close to 25 MPH using only 36V after spending only 2K. And then later, when this 36V pack needs replacing, if I feel like it I can upgrade to 48V lithium and probably exceed 25 MPH. Only issue with 1 or 2 is I'm spending a lot of money on not the latest tech, I'm not sure if Series or Sepex motors are still recommended in 2023 or if everyone is doing AC motors now. |

Find the label on your controller because it might handle 48 volts. Some of the bigger ones they installed would.

My only concern with that one is that the 36/48 kit only comes with a 10HP motor. The plum quick cobra series motor is 13.7HP at 36V and jumps up to 16.7HP at 48V. So what is going to be a better motor? A high horse power series motor or a lower horse power sepex motor? Are any of these options going to be able to achieve my goal of running 25 MPH with 4 adults? Also, so you're not biased, I'm planning on buying my controller from carts unlimited with either option 1 or 2. |

Re: Recommended upgrade path for 36V Ezgo
It must be the week for odd controllers. A 1214 shows a 24 pin connector and is pretty much made for a forklift. Doesn’t show where it can use an ITS throttle. Do you know what throttle that you have?
