I am buying new servos for my 1/8 buggy and figured I may as well upgrade to LiPo batteries (servo's I am looking at recomend LiPo batteries)
I know nothing about them so is there a thread somewhere or a site that I can read that will teach me?
The ones I am looking at are different in 2 ways, one has a balance plug? (what is it and what does it do) and is labeled as 8C, what does that mean?
The other one is no balance plug and labeled as 3C
Also it advises I use a voltage regulator, any recomendations on that front?

Thanks for all and any advise.
