The containers are designed to be used independently or with Gridfinity baseplates. The bottom has magnet holes for magnetized Gridfinity baseplates.

The containers when fully loaded are stackable.

The battery model number is printed on the outsides and the insides whenever feasible.

The design tries to find the best trade-off between container's capacity, usability, stackability and robustness.

Gridfinity specifies container sizes with atomic increments of 42mm for the width (X) and the depth (Y), of 7mm for height (Z). For instance, a 1x2x4 Gridfinity container has sizes of 42mm x 84mm x 28mm.
