main storage for everything is a large padded camera bag with dividers (Think Tank airport series, the largest non-wheeled one). Inside each section gear is in little clamshell cases or boxes or bags with silica packs, depending on what it is, and since I always put things in the same place it gets easier and easier to grab the right recorder, batteries, cables, capsules, stealth props, etc. fairly quickly.
Then for air travel all necessary items for a particular event or series go into a smaller padded carry-on camera bag with dividers along with various photo and tech items.
