I second that about the Hyperion Line of chargers. I've had the EOS 5i which is the AC/DC version meaning that you don't need a separate power supply to get the darn thing to work. I feel your pain man, but you really should have done a bit more research before making such an expensive purchase. You won't be disappointed with Hyperion, as the quality and structure of the unit is solidly built and very user friendly. i have no doubts that Losi re branded an already existing charger and then charged twice as much because they're LOSI and whatever has their name on it is gold, lol not. Re branding in this hobby is getting way out of hand, as you will find that for instance the same brushless motor used by 3 or 4 companies and the only difference is the decals or maybe the color of the motor can. It's not difficult to recognize the same qualities if you examine it closely enough, however they will try to trick the consumer by putting the photos at different angles from each of the companies. Your getting the same performance, but the price range always varies and is mainly priced higher by the companies that everyone recognizes the most. That's business for ya, and it's not just an R/C problem either.
I agree with what one of the other guys that said in this thread that Losi vehicles are good quality and used by many but apparently their electronics are piss poor.
