Interesting, When I had my ECO I thought about getting a Braile battery, I think they were about 15lbs. The comment about the Ohm battery shutting off if you run your car stereo or leave your lights was interesting. My 320i does that from the factory. If you shut the engine off you maybe get 5 mins of listening to music. I asked the dealer about that annoying feature and was told it is meant to preserve the battery.
