Benchmarking

Whenever you look at a new design of pack it is important to some benchmarking of that design in the context of other packs. Any new pack will be measured against some key pack metrics and hopefully using a standard list of benchmarking data. Hence a key part of BatteryDesign.net is to collect together some of the benchmarking material available for some of the important packs.
