I know there are options to deal with this like carrying a battery batpack, but it would be nice to increase the internal storage of, a drill for example, by combining it with a internal storage upgrade.
It could even be implemented using a new machine instead of the crafting table in order to balance it, but that's just an idea.
This suggestion comes from whenever i go mining with the diamond drill it doesn't really lasts that long and i'm quite far from the iridium one.
Let me know what you think.
