That's crazy! This is the first I heard of this insanity - Thank you for the heads up. Would be nice if Alltrax could bother to notify their dealers so we don't have to find this **** out on the forum |

Re: Brand New Alltrax DCX400 controller, solenoid, batteries, cables and nothing....h
UPDATE
Rolled it out of shop with only the rear body and seat in place and got some interesting looks from neighbors as I drove down the street. We don't really have any flat ground in our neighborhood but on the flattest ground I could find running down the slight grade I was running 32-35MPH and running up the same grade I was running 24-26 MPH at full throttle. Seems to me on true straight and level it should run 29-30 mph flat out. There is one very steep hill to get out of my neighborhood which kills most of the carts and they run 4-5 Mph going up the hill. I went up that hill holding 14 mph at full throttle. I typically won't make it run that fast but I wanted to see max speed on a hill that everyone hates to run in their carts. I have bugs in my teeth from smiling! |

Did that once .... then I was disappointed how much the rear seat and all the other weight slowed the cart down. |

I was doing 33MPH downhill at full throttle and my motor explode, taking the controller with it, when I lifted my foot and the regen braking kicked in. Of course, with my 17" tire height, the motor was spinning at 8k+ and I'm only running 42V, so the regen braking is stronger than it is with a 48V pack. Don't worry about it, but do keep it in mind. To replicate my expensive learning experience, you'd have to be going at least 43MPH with your 22" tires. ----------- When making speed runs to determine top speed, inflate tires to max allowed pressure and don't do a jackrabbit start at the beginning of it. Volts = Speed and when you begin the run with hard acceleration, the pack voltage drops like a rock and doesn't recover nearly as quickly as it drops. --------- I have next to no level ground in my area either and I occasionally have a little fun with the other carts in town. With a 10.3HP @42V motor (11.8HP @48V) and tiny tires, my cart does okay going up hills. |

Is there a way to turn off the regen or is that something that is built into the shunt wound motors that you can't stop? |

What got me in trouble was a combination of things. Over-revving the motor and then hitting it with max regen braking while it was running at near the max allowable case temperature. Take away one or more of those three factors and it probably wouldn't have bit the dust. A DCX400 is user programmable, so you can turn down or turn off the regen braking. plus a lot of other things. Have you connected your computer to the controller yet? |

I just got back from another shake out run and it is getting a little faster. This is only the second time I have taken it out. How valuable is regen braking for extending the charge on a battery pack? Does it put much back? It seems like the regen occurs so quickly that it wouldn't have time to put much in but considering the way that batteries charge but I don't totally understand the theory behind how that works. |
