Im looking for a lipo battery for my Rc10B4.2 race buggy running a brushless motor. What would be the better battery for dirt oval racing a 5000mah 25c 2s or 5000mah 30c 2s?

For as light as the buggy is, either batter will be OK. The 30c would be ther better battery of the two and should be fine for general use. The higher the C rating the better. If you find your motor is asking you for more power from the battery (pack will become very warm) you may need to get an ever higher discharge rate battery...maybe even try a 40C rated pack to start with.

I don't know what type of budget you have, but you will want some good packs especially if you are running on a high bite track.
