I recently put together an electric truggy and used deans throughout for the battery connectors. I am new to this truck as it does not handle like my nitro truck at all so I tend to crash at higher speeds alot. I actually had the deans come unplugged in the middle of the main. Is there another connector that will not do this. I dont want to resort to using non-polarized bullet connectors on the batteries. So what should I switch to?
