All batteries must be shipped by a ground shipping method. NBD is excited to introduce the Nitro Nectar Gold Series HV Lipo Battery Series! They use a different battery packaging technology that provides a better discharging rate for those who like to push the limit! They tested these batteries with their powerhouse 1S craft, the AcroBee BeeBrain BL BNF and they are built to keep up with the demand of raw thrust!  After 3 months testing, NewBeeDrone is ready to bring them to the market for whoop pilots across the world! Lightweight, durable and plenty of power to bring home the Gold! Check out our 1S battery selection, and all our NewBeeDrone gear! NOTE: These packs are designed to deliver a major amount of power!  With the discharge rate that gives these packs such power, you will feel pack sag much later than normal packs.  We suggest setting the low voltage reading to 3.5v and bringing it in to land at 3.3v.  You are able to fly below 3.3v but that may result in battery degradation. You will need a high voltage capable charger, such as our brand new Nectar Injector portable USB powered charger.
