Need some advice on batteries. Will be running 1/10th off road 2wd and 4wd modified buggy with 6 minute heats. I would like to know what "c" rating and "mAh" rating I should be looking at as well as a good charger...thanks.

Most people are running the shorty packs in buggy. 70c and up seem to be a good starting point for power (punch), higher mah (capacity) will help with longer run times.

I run the 4600mah shorty SMC packs in my 2wd buggy and 2wd SC and do not have any problems lasting 6 minutes.

Right on...thanks!

Depends if you are running stock or mod. In stock, a higher C rating becomes important.
