21700 Battery Pack
LanDazzle offers high-performance 21700 battery packs, designed to deliver superior energy storage and efficiency. With a focus on quality and reliability, our 21700 battery packs are ideal for a wide range of applications, including drones, power tools, and robotics. We provide tailored solutions to meet the specific voltage, capacity, and discharge requirements of your project, ensuring optimal performance.
Traditional 21700 cells are rarely used in drones due to their weight, limited discharge rate, and lower space utilization compared to LiPo batteries. However, our advanced 21700 battery technology has successfully overcome these challenges, making them an ideal power source for UAV applications. Our 21700 battery packs break the limits of traditional cells. With 36C high discharge, they deliver the instant power drones need.
Our 21700 battery pack delivers 10,000mAh—the same capacity as a LiPo—but in a smaller, more compact footprint.
Optimized Space Utilization: Its compact size allows drones to make better use of internal space.
Lightweight Design: Reduced weight improves flight efficiency and extends airtime.
High Power Output: Despite the smaller size, it supports high-discharge performance for demanding UAV applications.
Conclusion: More power, less space, and better flight performance—all in one advanced 21700 battery pack.
Our 21700 battery pack delivers 10,000mAh—the same capacity as a LiPo—but with a lighter weight of 900g compared to 1,140g for a LiPo pack.
Optimized Flight Efficiency: Lighter weight reduces the load on drones, improving maneuverability and overall performance.
Extended Airtime: Less weight means longer flight durations without sacrificing power.
High Discharge Performance: Despite the reduced weight, it still supports high-discharge demands for advanced UAV applications.
Conclusion: Same capacity, significantly lighter, and optimized for superior drone performance—all in one 21700 battery pack.
Cylindrical battery packs have inherent safety advantages over lipo batteries, mainly due to their structure and materials:
Sturdy Metal Casing: Cylindrical cells feature metal shells that protect against impact, puncture, and compression, reducing short-circuit and fire risks compared to flexible lipo batteries.
Even Pressure Distribution: The cylindrical shape evenly distributes stress, while lipo batteries risk localized pressure that can cause internal short circuits.
Stable Internal Structure: Cylindrical cells maintain a fixed, stable structure, while lipo cells can shift under pressure or swelling, increasing short-circuit risk.
Better Thermal Management: Metal-cased cylindrical cells dissipate heat more evenly, while lipo batteries risk localized overheating and thermal runaway.
