I've bought a half dozen Lipo Batteries from Hobby King for my electric heli's. Great stuff for your buck. Honestly I rather support my local hobby shop here in the good old U.S.A, but unfortunately Hobby King has the best prices. I have bought batteries from hobby king and accessories from Tower Hobbies (on the same day) - with express shipping from hobby king I received my batteries in 4 days. In Hong Kong or China (where ever there located) they must be working on weekends. I ordered Thursday night and received the batteries Monday afternoon. I received my tower hobby stuff Friday - a week later.

If you order from Hobby King - pay Express Shipping (few bucks more). If you do it registered - it takes a few weeks (like 3). If you order it express you better be home - USPS will need your signature.
