Lipo case (infinity 4S 1500mAh or similar)

thingiverse

This is the final version of my lipo protector/case/condom for infinity 1500mAh 4S type batteries. It has reference values of 32x34x78mm. However, it can be easily scaled to any battery size by considering the appropriate factors. I intend for it to be printed in flexible filament (I've used filaflex), with a wall thickness of around 0.8-1.0 mm and an extremely low infill factor (5-10%). The base and side columns are internally reinforced, particularly where impact is more likely. This will save your lipo from mild everyday crashes and prevent small deformations. But don't expect miracles if you hit a wall or it falls from 30m on concrete (but it still helps!). With these parameters, it would add around 10-12g to your quad, which I can live with.
