There are a few things to consider, 1 is fitment? What does the battery that comes with it look like? If it is a standard stick type battery you have many options. If it is not, then you ate limited. Next the battery connector, which younalready mention. These connectors are pretty easy to replace if need be but there is a good chance it is a standard Tamiya connector. If you post up a picture of your current battery I am sure I can provide more info.
