Just ordered the Slash 4x4. I want to go lipo for sure, but don't know what battery/charger. I want to be able to race it later on so a legal battery would be nice. What is that? 2s? I would like to know EXACTLY what I should order, such as connectors and what not. I can solder so that's not a problem. I think I have it narrowed down to the Thunder ac6 charger, but I'm totally not sure what battery. I don't want something that's uncontrollable, just fast and long run times, so the cheaper the better. Thanks guys
