When designing a battery pack you will always be asked to benchmark it. For this there are a number of key metrics:
- Wh/kg – Pack Gravimetric Energy Density
- Cell to Pack mass ratio
- Cell to Pack volume ratio
- Durability – % of pack capacity available after 10 years
A first look at pack metrics versus application and what is important and what is not.
5 = important
1 = not important

When looking at designing a battery pack it is a good idea to look at the other designs that are out there on the market.
