Ultra-high density battery vests give next-gen soldiers twice the energy

This is a nice improvement although I hope that this results in lighter batteries rather than the same size conformal batteries with more power. The problem was always weight. It sucks to have 30lbs of batteries in addition to the 60lbs of regular gear you had. Not to mention every conformal battery I saw was a decade old and could barely hold a charge but that is a different issue.

Am I right in surmising that these are single-use batteries?
