1/8 buggy problem

Have you even read the instruction manual that came with the XERUN 150A????

How have you set your LVC? Is it set to auto cell detect? What I mean did you set the LVC for 3S battery or is it in auto detect mode?

And what the hell did you solder that with???? Cigarette lighter? That is some of the worst soldering I have ever seen. No joke there. Get that fixed up asap. If you can't do better take it to a hobby shop and pay to get it done. That is just asking for a disaster the way it is now.

lol ye its on 3s

What you are describing (your problem) seems to be something I saw very recently with that same ESC. With these ESCs you can't use Auto cell detect for LVC with 3S or 5S. If the ESC sees an input voltage of higher than 8.4V it will automatically asume that a 4S battery is hooked up. A fresh, off the charger 3S pack is around 12.6 volts which is around the cut off voltage for a 4S pack. In the case I saw it caused the ESC to kick in the LVC mode instantly. The car would only crawl very slowly for a while and then stop altogether.

What I had to do is with the programing card change from auto cell detect to 3S lipo and then set the LVC for 3.2V/cell. I had a same issue with my buggy when I tried to run 5S with the XERUN 150A ESC.


Also what motor are you running? Any chance you overheated it? That could cause demagnetization of the magnets and for the motor to loose pretty much all the power. Also check and reset your end points. Your ESC might not be seeing full throttle.

the car was on 3s, and yes when l changed it to auto cell correct it went to 4s. wat do u mean "set the LVC for 3.2V/cell", wer about is that on the the card. heres my motor, what should l use to make the battery in series (ie what wire, lve got a 12 guage high current cable, would that be any good? http://teamtwisterhobbies.com/produc...7c762ec8f0fdbc
