Modular multi-model battery storage box - replaceable modules, freely adaptable to different battery types, material-saving

This modular battery storage box is divided into a base, a top cover, two middle frames, and multiple sets of battery holders Among them, the base, middle frames, and top cover are nested and installed together, featuring a locking structure to ensure they won't easily fall off, though it cannot prevent separation due to severe impacts Battery holder sets are embedded in the two middle frame layers in the same order, and a slight angle is needed for insertion during installation

Currently, there are 3 types of battery holder sets available for 18650, AA, and AAA batteries, which can be freely combined to suit your battery storage needs A series of modules will be prepared later based on demand The first model can currently accommodate 4 sets of battery holders per box Each 18650 holder set can store 4 18650 batteries, each AA battery holder set can store 4 AA batteries, and each AAA battery holder set can store 6 AAA batteries For different battery storage requirements, simply replace the holder sets without having to repeatedly print different storage boxes
