A belt storage for promethium. Two variants: 14x14 and 26x26. It is not tillable, but easy to connect. The small variant can store 3800 chunks and the large one 15171. Since there is only one input and one output connection, the large variant takes quite some time to fill up. If speed is a requirement for you, I recommend using multiple small belt storages.
