The major problem with the current sub-c race cells is that they pack to much capacity in a size that is to small. It seems that battery manufacturers seem to think that they need to beat each other by releasing the highest possible capacity cell. When you combine this capacity with low IR and high average voltage you get a cell that is not very consistent and has a short shelf life.

To get more reliable cells we would need to go backwards in capacity but it has been my experience that once there is a higher mAh cell available racers want to buy it so going backwards is not an option. We could go to bigger cells but the sanctioning bodies wouldn't allow this as EFRA and BRCA went the opposite direction buy forcing the cell manufacturers to make the cells smaller for 2008.

With the current improvements made in the Lipo market Lipos will give you the same or better performance than sub-c cells and they are defintately more reliable but proper care and charging is a must.
