Lifted Ezgo with 400 Alltrax DCX
Hey guys,
I installed a 6” lift with 22” tires on my EZGO DCS 98 36v cart over the weekend. It has the 400 Alltrax DCX controller in it, which from everything I read before purchase said it would be good with 22” tires. We took it out for the first time yesterday and it did alright on long hills. It wasn’t flying by any means but kept moving which is fine. The problem I have is while moving slowing and trying to go up some little short hills it would completely stop and not move, no tire spinning nothing. It was still getting power but just didn’t have enough power to move itself up the little hill. So I had to reverse and get a little momentum. I’m thinking that’s maybe not right but idk. I was wondering if there is something I can adjust on the controller to increase the torque? I am good with losing a little speed if I can increase it but I am not sure what setting if any I need to look at and try to adjust. Is there anyone that might know about that? Thanks, |

How low does your battery pack voltage drop when on those hills. This is During, not before, not after, not sitting in the garage (before or after charge). I only need readings during your trip up the hill that causes the problem.

Re: Lifted Ezgo with 400 Alltrax DCX
We were out in the woods and I did not have a volt meter with me. I can check it the next time and see what it is reading during the event. I know the electric carts are heavy but they typically have enough power for a tire to spin in dirt or gravel don’t they? The batteries are about 5 months old also if that matters at all.

Re: Lifted Ezgo with 400 Alltrax DCX
I’ve been stuck on hills before because my controller got hot and went into “limp mode”. After a few minutes of cooling down we were in our way again.
A fan might help. But these Electric carts get hot when pushed. |

Re: Lifted Ezgo with 400 Alltrax DCX
It doesn’t sound like the controller went into thermal shutdown, though maybe it was close. It sounds like it just doesn’t have enough power, which is why cgtech wants the pack voltage.

Re: Lifted Ezgo with 400 Alltrax DCX
Yea it kept going just fine afterwards, just didn’t have the power to make it up the little incline at that low speed. Anyone know what I should have the throttle curve set to or does that make much of a difference? Think it’s on progressive now but didn’t know if any others would be better? I can’t seem to find the description anywhere of what those throttle curve setting are..

Re: Lifted Ezgo with 400 Alltrax DCX
Did you upgrade the cables to 2 gauge to make use of the extra amps from the controller. I upgraded ALL of my cables on my Medalist. That made a huge difference. I have 20 inch tires and a lift kit. I can take take off from a dead stop on all hill with no trouble.

Re: Lifted Ezgo with 400 Alltrax DCX
Get a digital battery meter and stick it on the dash. If the battery pack voltage is dropping significantly 6-7 volts or more you are in serious danger of cooking the motor.
The lower the voltage goes the higher the amperage draw goes. The motor can't convert all that amperage into motion so it turns it into heat the tat melts the motor pronto. So be careful and get that meter so you can answer gctech's question. |
