Always check the battery polarity before connecting USB power. Incorrect polarity may cause irreversible damage to the equipment.
When using the VTX in maximum power mode, make sure the VTX antenna is firmly connected before turning on the power. Operating at high power without a properly connected antenna may cause irreversible damage to the equipment or burnout of the VTX.
„The NewBeeDrone LionBee Long Range Developer Kit is a completely new approach to building 1S long range FPV drones. The LionBee is designed with an innovative flight controller integrated directly into the 18650 battery housing. This solution reduces vibrations, simplifies the design, and improves electrical efficiency - a solution that is practically unprecedented in the FPV world.
To achieve true 1S long-range performance, LionBee uses a special 0.5mm brass high-current transmission system. It eliminates the main drawback of traditional 18650 battery holders - limited current throughput. As a result, modern high-discharge 18650 cells such as the JP30 can reach their full potential and provide enough power even for freestyle flights using a single cell.
„LionBee also features the world's first 1S ESC based on a 32-bit microcontroller, developed in collaboration with the AM32 team. The system is based on a powerful AT32F435 288 MHz processor, which provides fast flight control, video transmission and operation of the integrated receiver.
Despite the single-sided PCB design, the system has an integrated 800mW Smart-Max VTX transmitter that automatically adjusts power based on temperature, ensuring stable and secure video transmission over long distances.
Full reverse polarity protection protects the electronics in case the 18650 battery is accidentally inserted backwards. In this case, neither the FC, nor the ESC, nor other components will be damaged - this is extremely important when using the drone in outdoor conditions. However, it is important to note that this protection does not work while the USB cable is connected.
The updated modular battery housing has factory-soldered brass contacts and can be quickly replaced after impact or damage.
„LionBee is presented as a Developer Kit – a platform for pilots, engineers and enthusiasts who want to experiment and contribute to the development of the next generation of micro long-range FPV drones. It is not only a product, but also an open experimental platform for further development and ideas from the community.
