I have a traxxas slash ultimate and a 5000mah and 5800mah 25C lipo batteries. I couldn't find this on the forums, but I am having some troubles with this equipment. When I plug in either of the batteries and turn on the traxxas, it powers up immediately at full throttle. My transmitter can't turn it or make the breaks work. I'm not sure if it's the batteries, the transmitter, the wires, or even something else that's causing this. A couple of days ago, even just this morning, it worked fine. If anyone could please help, that would be awesome.
