On my UDR, I run a few sets of HOOVO 11.1V 3S LiPo Battery 5200mAh 60C with Tr Plug and they fit perfectly. The plug isn't technically the real original traxxas female plug but it is designed to fit into the traxxas male ports. These batteries are the perfect width, and 2 stacked is the perfect height, and the length is pretty much right where you'd want it, too without needing spacers. They also have a warranty (I forget the length) and I have used it and its really good. I accidently left one of my batteries stored with charge for too long (totally my fault) and they still sent me a replacement after mine went bad. They're also pretty good price wise and they generally go on sale for amazon prime day or black Friday sales.
