I have 2 racers edge lipos and latley the wire leads keep popping out of the battery at the worst times due to the bouncing of my sct. yes i know i need to drive smoother but for now what can i do to keep the leads in the case? Can i solder the plugs directly to the battery? thanks

To make an assumption, I'm going to assume there is a 4mm bullet that is the last point of contact going into the battery and that is what is popping out. Replacing those with better ones that have a larger area of contact like these will usually do the trick.

yes that is the problem. i will pick some up and give it a try. thanks for the advice

The 'umbrella' style bullet connectors don't wear very well, the 'leaves' break off and they get weak and don't stay connected too well as you're finding out. Those pictured will get weaker over time and use also, but can be re-sprung with the tip of a knife blade and are pretty much like new again. They are def better connectors.
