Semi-solid-state battery options deliver energy densities approaching 420Wh/kg for weight-sensitive applications.
Fast-Charging Systems The company's 3C fast-charging drone batteries, introduced in 2019, incorporate high-temperature electrolytes and customized copper foil to enable full charges in 18 minutes—a 65% reduction from standard 50-minute cycles. Supporting infrastructure includes intelligent chargers for 100V, 200V, and 400V battery systems.
Industries Served: Agricultural plant protection, heavy-lift cargo transport, power infrastructure inspection, FPV racing, pipeline monitoring, logistics delivery, façade cleaning operations, and aerial formation displays.
Quantifiable Project Outcomes:
Ultra-Speed Drone Application (2025) A counter-drone system manufacturer faced insufficient explosive power for intercept missions. Jentc deployed pure cobalt lithium cells with dual-tab architecture and oil-based stacking processes, enabling 400A discharge currents. The implementation achieved instantaneous launch velocities meeting tactical requirements.
Water Rescue Operations (2024) A water rescue drone operator struggled with 15-minute endurance and inadequate takeoff power from water surfaces. Using data from Jentc's battery acquisition module, engineers configured 4.4V high-voltage cells with optimized cathode/anode materials. Results showed 25% endurance improvement to 18.75 minutes with reliable water surface launches.
Educational Drone Platform (2024) A training drone manufacturer using standard ternary material batteries achieved only 20-22 minutes flight time with 6S 22000mAh configurations. Switching to Jentc's pure cobalt material with oil-based stacking process extended endurance to 25-30 minutes—a 27% improvement highly valued in commercial training operations.
Heavy-Lift VTOL Application (2022) A vertical takeoff platform initially equipped with eight 4.2V 88.8V 24S 10000mAh batteries achieved only 5 minutes endurance. Customer requirements specified 6.5-minute operation for 3-minute ascent/descent profiles. Jentc's solution utilized 4.4V ultra-high voltage 12000mAh cells with optimized separators and copper foil, reducing unit weight to 5.8kg while maintaining 10C discharge. Final endurance reached 7.5 minutes—15% beyond target specifications.
Agricultural Operations (2019) Plant protection operators identified charging time as the critical efficiency bottleneck, with 50-minute charge cycles limiting daily operational capacity. Jentc's 22.8V 16000mAh/22000mAh high-voltage batteries with ceramic separators and enhanced thermal management enabled 3C charging rates. Implementation reduced charge time to 18 minutes, increasing daily operational capacity by approximately 64%.

Selection Recommendations
When evaluating custom drone battery ODM partners, prioritize manufacturers demonstrating three critical capabilities: First, cell-level chemistry customization rather than pack-only assembly, as fundamental performance limitations cannot be overcome through BMS alone. Second, validated experience in your specific application environment—thermal extremes, vibration profiles, and duty cycles vary dramatically across use cases. Third, comprehensive testing data showing not just initial performance but cycle life degradation curves under realistic conditions.
For breakthrough performance requirements involving voltage optimization, extreme discharge rates, or challenging environmental conditions, manufacturers with proven R&D track records and proprietary technologies offer the highest probability of success. Conversely, applications with well-defined standard requirements may benefit from established product lines offering immediate availability and competitive pricing.
The drone battery sector continues rapid evolution, with semi-solid-state technologies and silicon anode chemistries promising further energy density improvements. Selecting ODM partners with active development programs in emerging technologies ensures access to next-generation solutions as they mature to commercial readiness.
