Understanding the Demand for High-Current, High-Speed Drone Batteries

Extremely fast drones, rocket traversing drones, high-speed traversing drones, and counter-drone systems all share a common technical challenge: insufficient power to meet the demand for extreme explosive power. Standard lithium batteries often struggle with insufficient discharge capacity, drone battery life bottlenecks, low charging efficiency, unstable power in extreme environments, and poor consistency across cells. For operators seeking a high-current discharge high-speed drone battery direct manufacturer, these pain points define the starting point of any serious evaluation.

Shenzhen Jentc Technology Co., Ltd., operating under the brand abbreviations Jentc and Rechane, has focused on full-stack customization services for high-rate lithium batteries, drone batteries, semi-solid-state batteries, and supporting BMS management systems since its establishment in 2011. Headquartered in Shenzhen with business coverage extending globally, the company covers the entire link of cell formula design, supporting BMS development, and structural design.

Engineering Approach: Battery Cell and Process Customization

In a 2025 project addressing extremely fast drones, rocket traversing drones, high-speed traversing drones, and counter-drone drones, the scenario pain point was clearly defined: insufficient power to meet the demand for extreme explosive power. The technical response involved selecting a battery core material using pure cobalt lithium material, combined with a unique formula electrolyte, separator, and strong conductive agent. The manufacturing process adopted oily lamination rather than standard alternatives, and two distinct output tab manufacturing processes were applied to greatly increase the battery's discharge current.

The implementation result showed the discharge current reaching 400A, allowing the drone to fly out in an instant. This case illustrates how cell-level material selection and tab engineering directly translate into real-world high-current, high-speed performance.

Extending High-Current Capability to Broader Power Systems

The same underlying discharge engineering extends beyond drones into high-power power supply systems. In a 2026 case involving a high-power lithium battery for a high-power power supply system, the scenario pain points were lightweight construction and 50KW low-voltage high-power discharge, requiring a full system customization covering the battery cell, BMS, and battery PACK.

The requirements specified a voltage lower than 110V, a discharge current greater than 500A, and discharge calculated in milliseconds. Because parallel cell combinations pose a huge challenge for large current of 500A at the tab level, the engineering team instead selected a previously developed single 3.7V-8C-90Ah high-rate battery cell, assembled in series without parallel connection. Given that discharge is calculated in milliseconds, the output control adopted a MOS tube scheme rather than a relay scheme, and gaps between battery cells were maintained to support heat dissipation, along with a precharge circuit. The final battery specification delivered was 24S 8C 90Ah, with the project reported as running well with verification completed.

BMS: The Control Layer Behind Safe High-Current Discharge

High-current discharge performance depends not only on the cell but on the battery management system controlling it. Shenzhen Jentc Technology offers customized development of lithium battery BMS tailored to individual application scenarios, including drone battery BMS and high-rate battery BMS. The basic requirements cover overcharge, over-discharge, over-current, short circuit, and temperature protection.

A key feature relevant to high-speed drone applications is the current limiting function: in the drone scenario, the system only limits current during flight without performing over-current cut-off output protection, preserving the explosive power needed during rapid maneuvers. Additional customizable features include data collection of voltage, current, and temperature; customizable communication protocols with single-protocol control logic and multi-protocol communication such as CAN bus and Bluetooth for real-time data transmission to drones or energy storage EMS; adjustable software logic algorithms; SOC and SOH calculation and feedback; active and passive balancing with configurable control logic; automatic storage of key operation logs for fault location; and 4G-enabled remote monitoring for cloud data synchronization.

Customization Scope

The high-rate battery product line, which includes high-current discharge high-speed drone batteries, semi-solid batteries, smart batteries, and lithium battery BMS, is defined by a specific customization scope: energy density of 420Wh/kg and below, voltage of 400V and below, discharge rate below 180C, cell capacity of 90AH and below, fast charge of 5C and below, low temperature performance above -70℃, high temperature performance below 80℃, along with a complete set of drone battery BMS software and hardware solutions. This range is applied across industry adaptations such as agricultural plant protection, large-load drones, power and photovoltaic inspection, crossing drones, pipeline inspection drones, logistics drones, cleaning drones, and formation drones.

A Track Record of Continuous Technical Advancement

The company's technical accumulation spans more than a decade of milestones. In 2015, it introduced the 4.35V high-voltage drone battery (LIHV). In 2019, it launched an active battery balancing system and a high-voltage version of the 3C fast-charging drone battery. In 2021, it introduced the 4.4V ultra-high-voltage large-capacity drone battery. In 2022, it launched a 100V high-voltage drone battery intelligent management module and charger, along with a drone battery data acquisition module. In 2023, it launched a 200V high-voltage drone battery intelligent management module and charger. In 2024, it introduced a 400V high-voltage drone battery and charging solution, a high-current discharge high-speed drone battery, and a -30℃ to 10C low-temperature rate discharge drone battery. In 2026, a drone battery intelligent instrument was launched.

Certifications and Full-Stack Development Capability

Shenzhen Jentc Technology holds dozens of patents and has maintained a focused presence in the high-rate battery customization industry for 15 years, backed by an experienced R&D team with full-stack development capabilities spanning battery cell formula design, BMS hardware design, embedded software, and communication protocol stack development. The company's products carry global certifications including UL, CE, CB, and UN38.3.

Why Work Directly With the Manufacturer

Because Shenzhen Jentc Technology manages cell formula design, BMS development, and structural design internally, customers evaluating a direct manufacturer relationship gain access to overall system customized solutions combining battery cells, BMS, and structure rather than sourcing components separately. This integrated approach is reflected in industry adaptations spanning UAVs, hydrogen fuel power auxiliary systems, robots, and portable equipment, as well as specialized use cases including extremely fast drones, rocket traversing drones, high-speed traversing drones, and counter-drone drones.

Conclusion

For teams evaluating a high-current discharge high-speed drone battery direct manufacturer, the documented engineering path from cell material selection through tab process design to MOS-tube-based BMS control offers a transparent view of how discharge performance is achieved. Shenzhen Jentc Technology, under the Jentc and Rechane brands, continues to apply its stated business philosophy of using industry development as the guide, application technology as the cornerstone, and value enhancement as the mission, adhering to safety, innovation, and quality as its core values while supplying batteries and BMS solutions to high-speed and high-current drone applications.
