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.

The battery pack database is now available as an excel file via a download. This is $25 and gives high level data for a number of battery packs (see page for details).
