Just want to chime in about my experience with SMC Batteries and Danny. Danny has gone out of his way to answer all of my questions in detail with accurate testing to back it all up. He even went far beyond that to help me understand things I would have never even asked about and why they are important. When I ordered I received the batteries I purchased within a day of my order (I live close).
Now onto the batteries. I've been running the 4S 6500 Lipos in my E Buggy and after 10 minute mains with average laps in the high 40's, the batteries only take between 3600 and 4000 mah when re-charging . Punch across the entire main is consistent the batteries seem to run the same cycle after cycle. I have about 50 Cycles on 2 4S packs. I've run Nanotech's in the past, and the Losi Lipo Batteries and these have them beat hands down for the price and performance gain. If your on the fence buy and you will see.
