Taking the controller plunge
I have a 2002 pds i got it with the stock controller, lift, rear seat, 23" tires also it has 4 gauge wires. I plan to use the cart for:
Neighbor hood riding with the kiddos Dove hunting (flat pasture semi tall grass) two or three adults plus gear guns and ice chest with "water" Deer hunting just to the stand again flat ground with grass and hard packed trails flat ground On Scotty's website I'm looking at the #808 400 amps or the #909 500 amps So what do y'all think |

Re: Taking the controller plunge
I went with the 808B package (DCX400 with Super-Duty solenoid) originally, but was running stock height tires and exploded the armature in the stock motor while going downhill at 33+ MPH.
(It'll have a DCX500 and a D&D motor when I get it back together) That shouldn't be a problem for you since your 23" tires will keep the motor RPM down. With 23" tires, 4Ga cables might get a little hot with either a 400A or 500A controller unless you up the pack voltage to 42V or 48V. Suggest you go with the Super-Duty solenoid what ever controller you decide on, it works from 36V to 48V, so you don't have to replace it when you change pack voltage. |

My silver pds cart had 23" tires, a DCX500 controller, 48v, and stock motor. The 4Ga cables did get warm, not hot, just warm. If you can get 2 Ga cables if you run a DCX500. |

Re: Taking the controller plunge
If you're on a budget, you can save the cables for last.
EDIT: Since you plan on hunting with big tires, you should at least monitor how hot they're getting. |

Re: Taking the controller plunge
Yes I'm on a budget so cables will be my next upgrade. Is there a way to limit speed or rpm to limit speed I don't want to tear it up just make it better

Re: Taking the controller plunge
Also should add that it's a 36v with a stock motor

Re: Taking the controller plunge
This is just my opinion, but once you decide which way to go, cables should be the first thing you do, do #2 sized and never look back, cables seem to be the most overlooked part of sparkie builds, and will lead to trouble if not closely watched,
Also if you can, get soldered instead of crimped, you can do this yourself or have cartsunlimited (scottyb) do them for you. |

Re: Taking the controller plunge
Good point. I assumed 4 gauge cables on a stock motor/controller=new. Not necessarily.

You'd have to be going 42MPH on 23" tires to spin a stock PDS motor at the RPM I was spinning mine at when it failed. You are exhibiting good common sense by asking pertinent questions, so I'm pretty sure your common sense would kick in long before you reached that speed going downhill, even if your drive system was capable of producing it, which it is not. DCX controllers have a "Top Speed" slider that can be user programmed, but the way it works is by the controller interpreting the actual throttle position by the percentage the slider is set to. In other words, when set at 50%, the controller sees a fully depressed pedal as halfway depressed and a pedal depressed halfway as 1/4 throttle. Battom line: Motor RPM and Cart speed are locked together, so use a speedometer of some type and don't exceed a speed that spins the motor too fast. |

If crimped properly and sealed airtight they might suffice, but finding them might be a challenge. |
