Plagued with the current generic 2.0 plugs on the market, we got tired of being able to plug the connector in backward and possibly ruin your FC, so we made the best one possible.
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!
