Have you seen these? This is a three cell pack but also come in 2 and 4 cells enclosures.

Means you can use standard untagged cells and you can swap cells in/out for your battery charging or replacement needs.
This makes for a good external battery.
You would need to identify a way to lock the cells into the EN-EL4 for internal battery recelling. In this case it is probably best to use tagged cells.
