I would love to see batteries work more like the modules shown in this clip. Make the blocks attached to the ship receptacles for power modules to be placed into. so a large grid module would hold 4-6 and a small ship module holds 2. Maybe the little small grid block could use the smaller power pacs but don't get used up if installed into the block. The modules themselves would be made like the tanks requiring power cells and a few other components/materials. would be nice to have it work like a tool and hold it in your hands till its been placed. I would still have the block be able to store a litte power but to be fully effective it would need the modules to extend range and capacity.
