This Lipo protector is designed to protect your battery in a crash. The 3d printed TPU takes the majority of the hit instead of your precious lipo. These are a must have item when flying in a parking garage over concrete to reduce road rash to your battery.
The front of the protector has a built in 30deg angle to make sure you get the holeshot on the starting line. It also has a place for your 4s balance leads to keep it from getting tangled in the props.
Fits almost all 1500mah size batteries.
