Controller Type/ Amperage
Hi all,
New to forum and new owner of a 2009 EZGO PDS. It is lifted with 23” tires and has the red chip in the controller. Drives great. I’m just trying to learn as much as i can about it to decide what I want to upgrade as I am reading these pds carts don’t necessarily like to be lifted with stock controllers. Motor is stock, Controller I am told by previous owner has been upgraded ( he doesn’t recall yo what) but I cannot see any identifying labels or marks on it to know what it is. Does anyone know how to ID what amps a controller is? Is there a meter test or Would a picture help? Appreciate any help you can provide! |

I’m sure the experts on here (not me) can identify with a picture.

With the freedom chip (red wires) a PDS cart does 18.5 MPH on stock height (18") tires. Attached is a picture of a stock PDS controller. The picture of the controller posted above, does not have the Curtis label between the B- and B+ terminal, so it may be an aftermarket rebuild and might have been upped to 350A, but there in no way of telling short of opening the unit and looking at the power board. |

Re: Controller Type/ Amperage
Thank you, I suppose that would be an upgrade from stock ( stock is what 275 or 300?) MPH is no problem, with the speed chip and 23” tires I’m at 18-19MPH Flat land. My main reason for wanting to know was reading that the pds carts don’t like lifted/ big tires + speed chip, so assuming all 3 of those hurt the controller I was curious where I was at and if I should upgrade. Seems folks recommend the 400amp for this setup. Hopefully the 350 buys me more time than stock before it goes.
Also trying to troubleshoot low runtime ( about 5 miles with significant power drop after 2-3) Batteries 2yrs old and year and test good so trying to understand what the tire/controller / freedom chip combo is attributing to this. I might try the hill chip for some regen and to not hurt motor when I’m doing 30mph downhill. |

I suggested a 500A controller due to the 23" tires, but turn it down to 400A with a stock motor and turn it back up to 500A when you replace the stock motor with one suitable for turning 23" tires. |

Re: Controller Type/ Amperage
Thank you both very much. Seems the previous owner who built the cart did the right thing by upgrading the controller and wires for the tires but didn’t know enough that a 350amp upgrade isn’t really an “upgrade”. Thanks again!
