Drone Battery ODM Manufacturer: 15 Years of Expertise

Meeting the Demands of Modern Drone Operations

As unmanned aerial systems expand into agriculture, inspection, logistics, fishing, and specialized industrial roles, operators consistently face the same set of obstacles: insufficient discharge capacity, limited flight time, slow charging, unstable performance in extreme temperatures, battery bulging, poor cell consistency, and inadequate real-time monitoring. Shenzhen Jentc Technology Co., Ltd., operating under the Jentc and Rechane brands, has built its entire business around solving these exact pain points through full-stack customization of high-rate lithium batteries, drone batteries, semi-solid-state batteries, and the BMS management systems that support them.

A Fifteen-Year Foundation in High-Rate Battery Engineering

Established in 2011 and headquartered in Shenzhen, Jentc has spent 15 years focused specifically on high-rate battery customization, with business coverage extending globally. The company’s core values of Safety, Innovation, and Quality guide a business philosophy centered on industry development as the guide, application technology as the cornerstone, and value enhancement as the mission. This positioning has produced an experienced R&D team with full-stack development capabilities spanning battery cell formula design, BMS hardware design, embedded software, and communication protocol stacks—an integration that allows the company to address problems at the cell level, the electronics level, and the structural level simultaneously rather than treating them as separate engineering challenges.

Full-Stack Customization: Cells, BMS, and Structural Design

Battery Cell Customization

Jentc’s core differentiator lies in adjusting positive and negative electrode sheets, electrolytes, separators, and conductive agents to fit the specific demands of each application. The customization scope covers voltage up to 400V, discharge rates below 180C, energy density up to 420Wh/kg, cell capacity up to 90AH, fast charging at 5C or below, low-temperature operation above -70℃, and high-temperature operation below 80℃. This range allows the company to serve agricultural plant protection, large-load drones, power and photovoltaic inspection, crossing drones, pipeline inspection, logistics, cleaning, and formation flying, among other use cases.

BMS Customization

Because standard battery management systems often cannot meet the requirements of specialized flight scenarios, Jentc offers BMS customization built around each product’s specific application. This includes overcharge, over-discharge, over-current, short-circuit, and temperature protection as baseline functions, alongside a current-limiting function that restricts current during flight without triggering over-current cut-off. Additional capabilities include data collection for voltage, current, and temperature; customizable single- and multi-protocol communication via CAN bus and Bluetooth for real-time data transmission to drones and energy storage EMS systems; adjustable logic control algorithms; SOC and SOH calculation and feedback; active and passive balancing with configurable control logic; automated battery data recording for fault diagnosis; and 4G-enabled remote monitoring for cloud-based visibility into pack status.

Technical Milestones That Define Industry Direction

Jentc’s development timeline reflects continuous technical advancement: the 4.35V high-voltage drone battery (LIHV) in 2015; an active battery balancing BMS in 2019 alongside the high-voltage version of the 3C fast-charging drone battery; the 4.4V ultra-high-voltage large-capacity drone battery in 2021; a 100V high-voltage intelligent management module and charger plus a drone battery data acquisition module in 2022; a 200V high-voltage intelligent management module and charger in 2023; 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 2024; and a drone battery intelligent instrument in 2026. This progression follows an "Application Scenario + Innovative Technology" approach intended to improve overall drone performance while enhancing value for customers.

Certified for Global Deployment

Supporting its global business coverage, Jentc holds UL, CE, CB, and UN38.3 certifications, alongside dozens of patents accumulated over its 15 years in the high-rate battery customization industry.

Proven Performance Across Diverse Drone Applications

Extending Flight Time in Real-World Missions

In a fishing drone case, a customer’s 22.2V 6.5Ah ternary rate lithium battery weighing 1000g and delivering roughly 16 minutes of flight time was replaced with a 23.1V 10AH semi-solid battery weighing 1100g. By applying a unique formula, separator, and strong conductive agent while keeping weight nearly unchanged, flight time increased from 16 minutes to 24 minutes—a 50% improvement. In a pipeline and indoor inspection drone case, switching to a 4.4V high-voltage battery solution with adjusted positive and negative materials, electrolyte, separator, copper foil, and conductive agent formulas extended flight time from 15 minutes to 18 minutes. In a training and education drone case, adopting pure cobalt materials with oil-based and lamination processes increased the 6s22000mah configuration’s flight time from 20–22 minutes to 25–30 minutes.

Solving Extreme Temperature Challenges

For a northern inspection drone and drone nest application, a customer’s 15.2V 6.7Ah high-rate battery with a 1C maximum charging current required preheating before operation. Jentc’s customized 15.2V 10AH battery, rated for -40℃ operation and 2C fast charging, used low-temperature electrolyte and related measures to eliminate the preheating requirement, enabling immediate flight operations. For a high-temperature drone application, a customer’s 22.2V 10Ah cylindrical high-rate battery rated for -20℃ to 60℃ was replaced with a 22.2V 10AH battery engineered for 70℃ operation using a unique high-temperature electrolyte and modified pole piece treatment, meeting the elevated operating environment requirement while preventing high-temperature bulging.

Enabling High-Voltage and High-Power Systems

In a large-load, vertical take-off and landing UAV case, replacing an 8-cell 4.2V, 88.8V 24S 10C 10000mAh configuration with a 4.4V ultra-high-voltage battery cell, adjusted separator and copper foil formulas, and increased capacity to 12000mAh at 10C produced a battery weighing 5.8Kg with energy density increased by more than 25%, extending flight life from 5.5 minutes to 7.5 minutes and exceeding the customer’s 6.5-minute target. In an underwater drone case requiring 320V maximum voltage, Jentc applied a semi-solid battery with 360Wh/kg energy density in an 84S 50Ah configuration, supported by a 1-master, 3-slave BMS architecture with insulation detection, liquid leakage detection, and CAN protocol communication, delivering a system verified as running well. In an extremely fast drone case involving rocket traversing and counter-drone applications, a pure cobalt lithium formula combined with oily lamination processing and modified output tab manufacturing achieved a discharge current of 400A.

A Business Philosophy Built on Safety, Innovation, and Quality

Across every case, Jentc’s approach follows a consistent pattern: identify the specific pain point of the application scenario, then adjust cell formula, BMS logic, or structural design—often all three—to resolve it. This methodology has been applied to plant protection drones facing charging bottlenecks, where a redesigned 22.8V battery reduced charging time from 50 minutes to 18 minutes, as well as to high-power and special vehicle systems requiring precise control over discharge timing, insulation safety, and low-temperature startup.

For manufacturers and operators evaluating a drone battery ODM partner, Jentc’s fifteen-year specialization, full-stack cell-plus-BMS-plus-structure development capability, documented technical milestones, and internationally recognized certifications provide a verifiable basis for evaluating fit against specific operational requirements.
