lipo selection?
 

I'm doing a x-crawler build, I am using a 2 rooster crawler esc's, what size lipo's should I use, I am also running novak 55t's.. TIA

Well 2S is the max the rooster will take. As for Mah... I advise to get the biggest you can fit... it will last longer and the crawler has some space to spare... I personaly have a 4000Mah, with two 65T motors, and it works good, and I usualy get bored of driving the truck before I get to have a dead battery.

How much run time do you think I'll get with novak 55t's and rooster esc, with a 1500 mah, or a 2000 mah?
