New to Lipos.

There seems to be alot of numbers surrounding these packs. What do they mean. I'm somewhat lost.

I'm looking to use a 35c 5000 pack, as that is what was recommended to me. What does the 35c stand for? I'm sure 5000 is milliamps... but which number does what?

Also, looking for a charger that will carry these type packs. I've been looking at the Team Orion Clubman Advantage Lipo Edition charger. It's in my price range, but I don't want something that won't do a sufficient job.

Thanks for any help!
