The battery slot is a bit too small for my 550mAh batteries. The case and cap are thick and solid, and they fit perfectly, but the batteries don't. Even if the design is fixed in the future, I'd recommend making the battery slot slightly loose so the batteries aren't a perfect, tight fit.

Perfectly fit with DJI O4 lite Axis case. You just need a DJI 15cm or longer coaxial cable for the camera (for 5 inches drone).

Very good one.
