NewBeeDrone Nectar Connector PH2.0 Clear Battery Lead
The Nectar Connector is a custom mold design with thicker plug walls that makes it literally impossible to plug a lipo in backward without breaking the battery side plug first. Never again will you fear if you have plugged in the right way and risk burning your FC.
The transparent plug design gives a great style and also lets you see the condition of your pins when troubleshooting power issues. If you even look close enough you can see the NBD letters!
