I'm going to be running 2wd mod buggy at my local track with a 10.5 vector motor. I'm not sure on which brand to go with, smc. orion, reedy, protek, there are so many brands, of course it has to be roar legal, any help would be appreciated.

Thunder power 50c 5200 mah for 110 @ superiorhobbies.com. amazing batts and will motor and put down a lot of power

has anyone ever used pro-tek lipo's or common sense rc packs, i've been shopping around and I cant make up my mind on what lipo pack to get, i'm gona be looking for 3800-4600mah 2s, let me know what your using.

I have 3 3S 3300 Protek transmitter lipos - 2 inactive use and one as a backup. Been fine.

I run 10.5 motors for my Mod stuff and for where I race it's more power than I can use, so having a battery with a huge C rating doesn't help any. If you're only going to run Mod all the brands you listed are fine and anything with a 4000mah/30C rating or higher is going to be fine. I don't run much stock stuff anymore but that's where I noticed a difference with the higher C rating packs. All IMO
