here is something i found on the hobbypartz forum...from another user
I used the 150A ESC with my Erevo. It says it will handle 6 cell lipo, which is why I bought it, but do not try it. I ran it on 6 cells and the ESC burned up. Apparently the overheat protection does not work so don't trust it either. I contacted Hobbypartz and they said they only warranty their items for 30 days - I had it less than two months. They told me they do not honor the warranty from the manufacturer which is six months. I contacted Hobbywing directly, but they are in China and have never responded to my warranty request. So be aware that the warranty on Hobbywing items is virtually useless.
