Most people change out the white Tamiya plug that is on that speed control. Other kinds give a better connection. Different people use different connectors. My brother and friends swear by Deans connectors, and they convert all their batteries and speed controls to them. I use Traxxas connectors, they are tough and easey to use, and can take a ton of current. I put them on everything. I am primarliy a basher, so my batteries don't directly soldier on, so they all get Traxxas. I don't know much about the bullet connecors on you battery, but I'm sure you can get an adapter for your charger and one to soldier on the speed control at your local shop or at Tower Hobbies. Don't cut off the Tamiya adapter (the white plastic molex type) on your charger though. That almost allways voids the warranty, and you can buy all sorts of adapters for them. Cutting them off the speed control also usually voids the warranty, but I always do it. It is not neccessary on the charger though.. I have adapters for my charger for Traxxas, and Deans in case my bro is over and we need to charge one of his.. Hope this helps some.
