I think he wants 10S lipos or more. I'm having one made, but it's being made from scratch. The guy that is making them is having some trouble with a car software. He told me that he has the forward/brake part done, but the reverse still needs work. It should handle 14S lipos. Patrick from Castle did mention a 12S capable MMM, but I think they are not going to make them anymore. The MMM coming out in my opinion doesn't reank as a HV. I have all the Aveox line of controllers and they have a L, M and H series. The H which is the HV one can handle 10S lipos or 32 normal cells. Forgot to add that the Jeti Spin 200 or 300 is not for cars. The only companies that makes a HV that has car software are: Schulze, MGM, BK (Might be limited on RPM range), Kontronik, Actronic and SinusLeistungsSteller (This seems to be one awesome controller
