My design is supposed to help astronauts contain batteries more efficiently. The battery holder can hold different types of batteries. This tool can hold multiple of the same type of battery because it can extend from a single battery holder, to a multiple battery holder. The battery holder also has a place where you can hook it up so it won’t float away in space. On one end of the battery holder, you can open this hatch to put batteries in. Hopefully, this tool will help astronauts contain batteries in a more efficient way so batteries don’t get lost in space.
