Re: New Headway 38120HP Cell
also consider that for two cells (of the same chemistry) with the same C ratings, the more energy dense cell will always be be more power dense (gravimetrically) as well!
As an example, given a cell of the same weight as the headway cell but with say 140Wh/kg, then the the latter cell is around 15Ah and therefore only has to output 11C in order to pull out the same current as the headway cell at 20C.
Edit: For this reason the proper way to classify cells is power density rather than C ratings (you can even compare batteries, or energy storage of any kind for that matter, of different types (e.g. chemistries) in a usefull sense that way), at least if one likes to compare apples to apples. C rstings probably is more something for the RC crowd I think.
