maybe a mini discharge coil system

Done

Something that could be interesting is a set of companion items, perhaps an undersuit and helmet? could just be cosmetic/a reskin of security equipment,
What they actually do would of course be up to you, but some operator equipment could be cool, hell, maybe even a special item that goes in the toolbelt slot for carrying spare batteries.

Added to to-do list. But for now i don't have spare time for texture work.

Perhaps mess with the suitcases scaling and allow it to be stored in crate racks?
Could be interesting, and at the very least it'd probably look cool.

Hmm, and can make it so that ordinary batteries are recharged at the battery recharge station, and not in the locker ? Or make a separate charging station for the batteries

ooooh jetpack maybe
or a jumping system since we cant in vanilla

Shoulder mounted tools and weapons

light pressure resistance version?
maybe to something like 2000-3000

Maybe add some arm-mounted eletric stun gun or flamer?

just wanted to say i love your idea of making a balanced exosuit all the others are very op
