Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
An Italian drone technology company was developing a mapping drone used for agricultural and land surveying applications. During testing, they found that their previous battery solution provided unstable flight time consistency, causing variations in mission completion time across identical drone units.
The customer contacted Lithotop looking for a stable and balanced discharge battery solution rather than extreme high-C performance. After analyzing flight duration, payload weight, and power consumption, Lithotop recommended the 4S 14.8V 5200mAh 35C LiPo battery for optimized balance between runtime and power output.
Lithotop focused on improving batch consistency by strict capacity matching, internal resistance matching, and discharge curve stability control. Connector selection was also optimized to ensure stable current transfer during long flight missions.
Sample testing included flight endurance testing, payload simulation, and repeated mission cycle validation. The customer confirmed improved flight time consistency and better mission predictability across multiple drone units.
Before mass production, both teams confirmed samples, discharge curve validation, connector specifications, and batch consistency standards. The final solution improved fleet reliability and reduced operational uncertainty in field mapping projects.
A US robotics education company was developing advanced training platforms for engineering students. Their previous battery supplier provided inconsistent discharge behavior, causing unstable robot performance during competition exercises and classroom training.
The customer approached Lithotop because they needed consistent medium-discharge batteries suitable for repeated educational use. After evaluating system load and training scenarios, Lithotop recommended the 4S 14.8V 5200mAh 35C LiPo battery.
Lithotop optimized production consistency through strict cell matching, discharge curve control, and connector reinforcement for repeated plug-in usage.
Sample testing included classroom simulation tests, continuous discharge cycles, and load variation testing. The customer confirmed significantly improved consistency across multiple training robots.
Before mass production, both teams verified aging performance, connector durability, incoming inspection standards, and packaging reliability. The final result improved teaching reliability and reduced maintenance issues in large-scale educational deployments.
