Which doesn't make sense; if they're not battery powered there's no advantage in reducing soldier payload.
Ele.me and ULS have a more interesting civilian product, which has about 6 hours worth of battery. Switching to solid state batteries (which'll be available and workable in the future), you'll get about 30 hours charge on the current load.
This is a pretty good technology, though, because once it's fully developed you'll have armored infantry capable of resisting any attempt by small arms to penetrate (i.e, armored enough to resist the new American 6.8mm) or otherwise capable of carrying formerly crew-served weapons like machine guns.
