Drone operations demand more than just lift—they need lightweight, high-performance power systems that can withstand harsh environments while maximizing flight time and payload. That’s why our lithium battery packs are purpose-built for UAV and drone platforms across commercial, industrial, and defense sectors.
In aerial systems, custom drone batteries play a critical role in powering flight controllers, motors, sensors, and communication systems. Junda Battery offers tailored solutions that support:
Extended flight endurance
Weight-optimized cell configuration
High energy density with low profile
Real-time BMS monitoring & balancing
Shock and vibration resistance
IP-rated casing for harsh environments
Compatibility with fast charging protocols
Reliable power in both cold and hot climates
With over 10 years of experience in drone battery engineering, Junda is your trusted partner for mission-critical energy solutions. Our team understands UAV power demands—and builds around your goals.
Junda Battery specializes in designing and manufacturing high-performance custom lithium battery packs for drones and unmanned aerial systems (UAS). From payload-carrying multicopters to autonomous UAVs, our battery packs are tailored for high discharge rates, weight sensitivity, and flight-critical reliability.
We provide customized drone battery solutions using LiPo, Lithium-ion (18650 & 21700), and LiFePO₄ chemistries to balance energy density, weight, and environmental durability.
Our drone batteries are designed for discharge rates ranging from 3C to 50C, meeting the burst and continuous power requirements of commercial and industrial drones.
We integrate smart BMS technology with overcharge, short-circuit, and thermal protection, SOC/SOH monitoring, and CAN/SMBus communication.

Yes. Our battery packs can be configured with BMS that support Pixhawk, CubePilot, or other flight controllers using CAN Bus, UART, or SMBus communication. Integration for real-time voltage, SOC, and cycle data is available on request.
Absolutely. All battery packs are fully customizable. You can define:
Voltage (e.g., 22.2V, 25.9V, 51.8V)
Capacity (e.g., 5Ah, 10Ah, 28Ah)
C-rate (e.g., 3C to 50C continuous or burst)
Dimensions, cable length, and connector type (XT60, XT90, AS150, etc.)
Our drone battery packs come with a smart BMS that offers:
Overcharge/over-discharge protection
Short-circuit and thermal protection
Fuse or MOS-based current limiting
Optional low-temp cutoff, fuel gauge, and active balancing
Yes. We provide low-temperature Li-ion and LiPo solutions capable of operating down to -20°C discharge and -5°C charge. Optional insulation, internal heating, or cell selection (e.g., high-drain 21700) can be applied for high-altitude UAV applications.
Yes. We offer full OEM/ODM battery development including branding, pack shape, BMS firmware, and connector customization. You can also integrate your drone battery into a swappable module design with housing and fast-locking terminals.
Depending on your market needs, our batteries can meet UN38.3, IEC 62133, ISO 13485, CE, and RoHS. All packs are tested for safety, performance, and traceability.
Cycle life depends on the chemistry:
LiPo: 300–500 cycles (depending on discharge rate and depth)
Lithium-ion (18650/21700): 500–1000+ cycles
LiFePO₄ (if used): 2000+ cycles
We also provide life-cycle test reports for your review upon request.
