Lipo charging question
 

I was out on HobbyKing looking at lipos and something struck me odd. For 3s 3500+ batterys, they say to charge at 2C. It was my thought that you charge according to the Mah of your pack. The Zippys that I have, or rather the zippy, a guy a the local track I used to visit boosted one of them, is a 3500 3s and I charge it at 3.5. I am doing something wrong or is the website off?

Most li-po will say to charge at 1c unless otherwise noted on the pack. Zippies are to be charged only at 1c I believe. You are correct in saying that you 3500mah should be charged at 3.5 amps...so a 5k could be charged at 5amp and so on

Most Lipos can only be charged at 1C of the packs rated capacity. Unless the manufacturer says other ways, always stick with 1C charge rate.
