DJI Mini 4 Pro Long-Endurance Battery Case (Empty)

A Mini 4 Pro long-endurance battery with a cracked shell but healthy cells is a common sight on a repair bench after a hard landing. This empty plastic case lets an experienced technician move the internals into a new housing instead of scrapping the pack.

This empty battery case is listed for the DJI Mini 4 Pro long-endurance battery. It's the plastic housing only; the listing doesn't mention cells or a circuit board, and it doesn't state DJI origin, so it's sold as aftermarket.

When a new case is the right fix

• The shell is cracked or deformed but the cells aren't swollen or damaged.

• The latches no longer hold the pack firmly in the drone.

• A rebuild project needs a clean housing.

Lithium safety first

Rebuilding lithium packs is work for people with the training and equipment to do it. Never reuse swollen, punctured or heat-damaged cells, keep a fire-safe area nearby, and avoid shorting the battery leads while transferring parts. If the cells are in doubt, recycle the pack instead.

For a pack with good cells and a broken shell, a new case is an inexpensive way to get it back in service.
