I just got a bandit vxl off craigslist and is my first brushless and want to go lipo power now. But Im not sure which one is the best. I have two off ebay that im thinking about:1)11.1v 25c 5000mah for $60w/traxxas connector 2)11.v 20c 5400mah with universal connectors for $60 also. I know the 11.1v are better for speed and the higher mah more run time. JUst wondering if anyone knows about what the best deal is on a lipo battery.
