Stack Upgrade (Extra Utilities)
The Stack Upgrade is an item added by Extra Utilities. It is mainly used as an upgrade for the Transfer Node (Items), Transfer Node (Liquids), Retrieval Node (Items), and Retrieval Node (Liquids). When put into an item node, it will pick up a full stack of items instead of 1 item per operation. When put into a liquid node, it will pick up 8000 millibuckets instead of 200 mb per operation. Only one upgrade is needed per node.
It is also used to craft the Ender Quarry Speed III Upgrade.
