*450Wh/kg is the specified energy-density rating provided for this series. Calculated energy-to-weight values may differ from the specified rating. Final specifications and test conditions should be confirmed before procurement or system integration. The 5C rating refers to instant discharge, not necessarily continuous discharge.
Choosing the Right UAV Battery Cell Capacity
Cell selection depends on target pack energy, available installation space, aircraft weight limits, and electrical requirements.
12000mAh – Compact UAV Battery Modules
The 12Ah cell measures 146 × 49 × 8mm and weighs approximately 106g. It is an option for engineers evaluating compact battery modules and weight-sensitive UAV designs where the available battery compartment is relatively limited.
16000mAh – Higher Energy in a Similar Cell Footprint
The 16Ah cell has a similar length and width to the 12Ah model, with increased thickness and nominal energy capacity. At approximately 133g and 59.2Wh, it provides another option for battery pack designers comparing energy requirements with physical dimensions.
22000mAh – High-Capacity UAV Battery Cell
The 22Ah cell provides 81.4Wh of calculated nominal energy and has a larger length and width than the 12Ah and 16Ah models. It is intended for evaluation in custom UAV battery designs where higher capacity is required and sufficient installation space is available.
Applications of High Energy Density Lithium Cells
Custom Drone Battery Pack Manufacturing
UAV battery pack manufacturers can evaluate these lithium cells for customized battery modules with application-specific voltage and capacity requirements. Series and parallel pack design must include appropriate cell matching, protection, electrical connections, and validation of operating conditions.
Industrial UAV and Aerial Surveying Systems
Professional UAV platforms used for mapping, surveying, and industrial inspection require battery systems designed around aircraft energy consumption, payload, and available installation space. The 12Ah, 16Ah, and 22Ah cells provide different capacity options for engineering evaluation in these applications.
UAV Research, Prototyping and System Integration
Drone developers and research teams may need individual lithium battery cells for prototype modules and experimental UAV power systems. The series offers three capacity options for comparing nominal energy, cell weight, and mechanical fit before selecting a final battery architecture.
Custom UAV Battery Cell and Pack Solutions
GSL ENERGY works with equipment manufacturers, UAV developers and battery pack integrators on customized lithium battery solutions. Selecting individual battery cells is an important part of pack development, but the final design must also address electrical protection, charging compatibility, thermal management, and mechanical integration.
Depending on project feasibility, OEM/ODM discussions may include cell selection, series and parallel pack configurations, connector arrangements, battery monitoring requirements, enclosure integration, and customer branding. Buyers can provide target specifications for engineering review.
