I just wanted to say that I have been running SMC batteries for years now. Started with Nimh and now running their Lipos. I have had great luck with their batteries! I have a "Lightning Volts" lipo I bought about 5 years ago and it is still running strong. I also have a 5200 mah C-Max lipo that I love, and I just picked up a 5600 mah Factory Spec pack. Could not beat the price. Thanks SMC for years of reliable power!
