After a recent lipo experiance, I switched to an SMC Lipo. I like it so much more. Lap time went from a 6.5 to 5.7 after a battery change. Also the cycle life on a higher quality lipo is alot more. Good luck getting customer support on the cheap ones also. Give them a try. I know the Yeah Racing ones are Superb. but IDK about that one on ebay. Zippy and Yeah are they best "inexpensive lipos". Also this said not to charge beyond 1.5 amps?
