Did you use the parts mentioned in a previous post (see below), or something else? Drop in an Alltrax XCT48400PDS controller and upgrade the solenoid (stock is only rated at 85A) as well as replacing all 10 of the high current cables to 4Ga or thicker |

Re: Help with possible PDS purchase
LBB,
While you're looking and pricing, you need to check out Scottyb's site. Best prices and advice around. http://www.cartsunlimited.net/ And he's a site sponsor! |

2. The "Freedom Chip" will get you about 18 MPH. Adding a rear seat will knock that down some. Acceleration is based on low end torque and motor produces the same torque in all four PDS modes, so acceleration will be the same in all four modes. Top speed and amount of regenerative braking are the only f-differences. 3. You can get an XCT48400PDS kit with a 200A solenoid for $479 at: http://www.cartsunlimited.net/alltra...-controls.html 4. Solenoid is part of the controller kit. 4Ga silver soldered cables are $179 for a 6 X 6V battery pack with a XCT controller. 2Ga are $209. |

So the chip won't improve acceleration. Based on your previous post, the new controller will though?
Darn - $200 for the new wiring is more than I'd hoped, but sounds like a wise investment if you replace the controller. |

Re: Help with possible PDS purchase
think of the wires as a water hose-only flow so much per there diameter...i made my own-but after seeing scottyb`s i would spend the bucks....2g for me.

The amount of torque produced by the motor determines the acceleration rate and torque is proportional to the amps flowing through the motor and a DC motor will draw the maximum amps it is capable of drawing at 0 RPM (stalled). A controller is an amp limiting device that limits the amp flow through the motor from 0A to the max amps it is designed to pass. By design, a stock PDS controller will pass 300A while an aftermarket controller designed to pass 400A will allow the motor to draw 33% more amps as it accelerates from 0 RPM, thereby increasing the acceleration rate. 2. 2Ga cable were my first upgrade. I got my 2008 PDS in 2011, so the OEM cables were only three years old and looked good to me, but I got a discernible increase in overall performance except for top speed, which was limited by the stock PDS controller. |

Re: Help with possible PDS purchase
The camo cart was already upgraded when I bought it, though I found they cut a few corners and had to add a few upgrades myself. It has the Altrax 500 controller with larger cables, solenoid, and tires. I liked it so much I bought another one and built it to keep at my farm. I bought all the components from ScottyB and it has been a trouble free cart. I've had one minor issue due to it sitting up too long, but a good cleaning of all connections fixed it. This cart has low pressure tires because I already had them and the cart is only used on dirt. They knock about 2 mph off the top speed, but this cart seldom sees top speed.
Beware of the carts similar to mine that you see for sale at feed stores and such places. Most of them have been lifted and bigger tires installed and maybe a rear seat added. They look good, but open them up and they are just stock underneath. Such carts are doomed to failure. They will run over 20 mph because of the tires, but won't last long. The controller JohnnieB recommended is an update from the ones I have. Also, the original controller on the camo cart failed after 2 years. It was used, so I don't know how it had been treated. But a 500 amp controller is too much for my factory motor anyway. I have turned them both down to 80% and essentially made them 400 amps. They lost a little torque, but I can't tell if it changed top speed. If it did, it isn't much. Good luck finding what you want. The PDS is a great system. |

Regarding #1. This makes sense. Thank you. So... + I've seen 500a controllers as well. My guess is that you need a better motor than the PDS has, that can handle more RPM to support a 500a? + Does 34v vs 48v relate to any of these factors? + If so, do any of the stock Ezgo carts handle a 500+a? + So I now think I understand how it affects acceleration rate. How does the new controller also allow more speed? (if it does) Sorry, but this is so helpful to know. :-) |
