Understanding the Heavy-Lift Drone Battery Challenge

Heavy-lift drones and VTOL (Vertical Take-Off and Landing) platforms carry demanding payloads, and their performance is directly tied to the battery system powering them. Common pain points in this segment include drone endurance bottlenecks, power instability in extreme environments, battery swelling or bulging, poor cell consistency, low energy density, weak high/low temperature performance, and charging safety concerns. For operators running heavy-lift missions, even a few extra minutes of endurance can determine whether a task is completed successfully. Addressing these challenges requires a manufacturer with deep technical control over cell chemistry, battery management systems (BMS), and overall structural design.

Shenzhen Jentc Technology Co., Ltd.—operating under the brand names Jentc, Rechane, Jentc World, and Ruichen—is a solution provider for high-rate battery industry applications. Headquartered in Shenzhen with business coverage spanning the globe, the company was established in 2011 and has since focused on providing a full set of customized services for high-rate lithium batteries and their charging and maintenance management systems.

Company Background and Core Values

Jentc Technology’s main products include high-rate lithium batteries, drone batteries, high-voltage batteries, fast-charging batteries, semi-solid-state lithium batteries, intelligent monitoring modules, intelligent balanced chargers, and power modules. These products serve drones, hydrogen fuel power auxiliary systems, portable equipment, and other fields. The company adheres to "Safety, Innovation, Quality" as its core values, and follows a business philosophy of "industry development as the guide, application technology as the cornerstone, and value enhancement as the mission," aiming to provide safe and more competitive green energy products.

The company holds dozens of patents and has focused on the high-rate battery customization industry for 14 years. Its R&D team offers full-stack development capabilities ranging from cell formula design to drone battery BMS hardware design, embedded software, and communication protocol stacks. Jentc Technology has secured global certifications including UL, CE, CB, and UN38.3.

Technical Accumulation Driving Heavy-Lift Performance

Jentc Technology’s technical roadmap reflects sustained investment in high-voltage and high-rate battery technology relevant to heavy-lift applications. In 2015, the company pioneered the launch of the 4.35V high-voltage drone battery (LIHV). In 2019, it introduced an active battery balancing system (BMS) and pioneered the high-voltage version of the 3C fast-charging drone battery. In 2021, the company pioneered the 4.4V ultra-high-voltage large-capacity drone battery. In 2022, Jentc launched a 100V high-voltage drone battery intelligent management module and charger, along with a drone battery data acquisition module. In 2023, a 200V high-voltage drone battery intelligent management module and charger followed. By 2024, the company had launched a 400V high-voltage drone battery and charging solution, a high-current discharge high-speed drone battery, and a -30°C to 10C low-temperature rate discharge drone battery. This progression supports the company’s "Application Scenario + Innovative Technology" route, which is designed to improve overall drone performance and enhance value for customers.

Case Study: Solving Endurance Limitations for Heavy-Lift and VTOL Drones

A representative 2022 case illustrates how these technical capabilities translate into real-world outcomes for heavy-lift and VTOL drones.

The Challenge

The customer’s application involved heavy-lift and VTOL drones, where flight time was too short and endurance time was only 5 minutes. The original battery configuration used 8 units of a 4.2V standard version, forming an 88.8V 24s 10C 10000mAh system. The scenario required 3 minutes for take-off and 3 minutes for landing, with other power systems used in between. The customer’s expectation was an endurance time of 6.5 minutes.

The Technical Process

Jentc tailored the solution to the application scenario requirements by adjusting product formula, material selection, and manufacturing process. First, 4.4V ultra-high voltage cells were used instead of standard 4.2V cells, providing a higher discharge platform. Second, the formula for high-performance separators, copper foil, and conductive agents was adjusted to reduce the overall weight of the battery while maintaining sufficient power, bringing each unit down to 5.8kg. Third, capacity was increased from 10000mAh to 12000mAh, with a discharge rate of 10C.

The Implementation Effect

The overall battery energy density increased by nearly 25%, and endurance time increased from 5.5 minutes to 7.5 minutes—exceeding the customer’s original expectation of 6.5 minutes. This case demonstrates how coordinated adjustments to cell voltage, material formula, and capacity can directly address the endurance and weight constraints common to heavy-lift and VTOL drone platforms.

Customization Range for Heavy-Lift Drone Battery Solutions

For heavy-lift and other drone battery customization projects, Jentc Technology offers a defined customization range: voltage of 400V and below, discharge rate of 180C and below, energy density of 420Wh/kg and below, cell capacity of 90Ah and below, fast charging of 5C and below, low-temperature performance above -70°C, high-temperature performance below 80°C, and a full set of drone battery BMS hardware and software solutions. This range allows the company to configure cell chemistry, BMS logic, and structural design according to the specific weight, power, and endurance requirements of a given heavy-lift mission profile.

The company’s differentiated approach centers on two elements. First, cell customization utilizes cathode/anode plates, electrolytes, separators, and conductive agents with superior performance, along with innovative formulas and processes, to increase energy density and support longer flight times and stronger power output. Second, drone battery BMS customization applies more reasonable SOC calculation and discharge logic to address battery swelling and discharge failure issues, while active balancing technology helps maintain cell consistency and extend cycle life.

Industry Adaptation and Broader Applications

Beyond heavy-lift drones, Jentc Technology’s drone battery solutions are adapted for agricultural plant protection, power and photovoltaic inspection, FPV drones, pipeline inspection drones, logistics drones, cleaning drones, and formation drones. This breadth reflects the company’s positioning around cells, BMS, and structure as an integrated system rather than isolated components, which is particularly relevant for heavy-lift and VTOL operators seeking a coordinated solution rather than a single off-the-shelf cell.

Conclusion

For operators and integrators evaluating a heavy-lift drone battery manufacturer, the combination of documented technical accumulation—from the 4.35V LIHV battery in 2015 through the 400V high-voltage solution in 2024—and a concrete 2022 case showing measurable endurance gains offers a factual basis for evaluation. Shenzhen Jentc Technology Co., Ltd.’s focus on cell customization, BMS design, and defined customization ranges provides a framework for addressing the specific endurance, power, and weight challenges that heavy-lift and VTOL drone applications present.
