Ive read through this thread with some interest and I think that most of you are looking at the c rating thing from the wrong direction. Do you really think that the rc market is the primary driver for lipo battery technology? If you do you really need to remove the blinkers and look around. The rc market is a drop in the ocean and holds absolutely no sway with the cell manufacturers.
The truth is tha battery performance is driven by the demand for cordless power tools and mobile phones and laptops and the emerging electric vehicle market, not by a minority market like rc. Its always been that way as far back as I can remember even when Sanyo were producing 1200 Nicads. you dont honestly think they came up with the 1700 sce to make your buggy go faster do you?
