Meeting the Complex Demands of Modern Drone Power Systems
Drone manufacturers across agriculture, inspection, logistics, underwater exploration, and defense-adjacent sectors face a recurring set of challenges: insufficient discharge capacity, limited flight time, slow charging, unstable performance in extreme temperatures, battery bulging, inconsistent cell performance, low energy density, and difficulty monitoring battery health in real time. Addressing these pain points requires more than a standard battery product—it requires a partner capable of full-stack customization across cell chemistry, battery management systems (BMS), and structural design. This is the space in which Shenzhen Jentc Technology Co., Ltd., operating under the brands Jentc and Rechane, has built its smart drone battery OEM/ODM services.
Founded in 2011 and headquartered in Shenzhen with business coverage extending globally, the company has spent 15 years focused specifically on high-rate lithium batteries, drone batteries, semi-solid-state batteries, and the BMS systems that support them. Its stated core values—Safety, Innovation, Quality—and its business philosophy of using "industry development as the guide, application technology as the cornerstone, and value enhancement as the mission" shape how it approaches each customization project.
A Decade and a Half of Focused Technical Development
Jentc’s OEM/ODM capability is grounded in a continuous sequence of technical milestones rather than a single product launch. In 2015, the company introduced the 4.35V high-voltage drone battery (LIHV). In 2019, it launched an active battery balancing system (BMS) and, separately in the same year, 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. Development continued in 2022 with a 100V high-voltage drone battery intelligent management module and charger, alongside a drone battery data acquisition module. In 2023, this progressed to a 200V high-voltage intelligent management module and charger.
By 2024, the company had released a 400V high-voltage drone battery and charging solution, a high-current discharge high-speed drone battery, and a -30°C to 10°C low-temperature rate discharge drone battery. In 2026, it introduced a drone battery intelligent instrument. This sequence reflects a "Application Scenario + Innovative Technology" approach, where each new product responds to a specific operational need rather than being developed in isolation.
Full-Stack OEM/ODM Capabilities: From Cell to BMS to Pack
The core differentiator of Jentc’s OEM/ODM model is coverage of the entire technical chain: cell formula design, BMS hardware and embedded software development, communication protocol stack design, and structural/PACK engineering. This allows the company to offer "battery cell + BMS + structure" as an integrated customized solution rather than assembling separate off-the-shelf components.
Customization Scope
For high-rate and drone battery projects, the defined customization scope includes: voltage up to 400V; discharge rate up to 180C; energy density up to 420Wh/kg; single-cell capacity up to 90Ah; fast charging up to 5C; low-temperature operation down to -70°C; and high-temperature operation up to 80°C, supported by a complete set of BMS software and hardware. For semi-solid-state battery projects specifically, the scope covers energy density up to 420Wh/kg, capacity above 5Ah, and discharge rate up to 10C. These parameters are applied selectively depending on the target scenario—an underwater drone project, for example, draws on different limits than an agricultural plant-protection drone.
BMS Customization Features
Because "special application scenario requirements cannot be met" by generic BMS designs, Jentc treats BMS development as its own customizable service line. Core protections include overcharge, over-discharge, over-current, short circuit, and temperature protection. Beyond these basics, the BMS can be configured with a current-limiting function that restricts current during flight without triggering over-current cut-off; data collection for voltage, current, and temperature; customizable communication protocols including CAN bus and Bluetooth for real-time transmission to drones or energy storage EMS platforms; adjustable software logic for scenario-specific control; SOC and SOH calculation and feedback; active or passive balancing; automated logging for fault location and maintenance support; and 4G-based remote monitoring for cloud data synchronization.
Proven Performance Across Diverse Drone Applications
Jentc’s project history illustrates how these customization tools are applied in practice. In a 2026 underwater drone project, the company delivered an 84S 50Ah battery pack using a semi-solid cell rated at 360Wh/kg, built from three 28S50Ah modules in a 1-master-plus-3-slave BMS architecture, with insulation detection, liquid-leakage detection, pre-charging, CAN communication, and emergency shutdown functions—verified as running well upon completion.
For a 2026 high-power power supply system requiring discharge above 500A calculated in milliseconds, the company used a single 3.7V-8C-90Ah high-rate cell assembled in series rather than parallel to avoid tab-current limitations, paired with a MOS-tube control scheme instead of relays, resulting in a verified 24S 8C 90Ah specification. A 2026 special vehicle power project produced a 48V 200Ah lithium iron phosphate battery with 2500W charge/discharge power, featuring interlocked charge-discharge ports, active balancing, and cold-start capability at -20°C without preheating.
In a 2026 fishing drone case, replacing a customer’s 22.2V 6.5Ah ternary battery (1000g) with a 23.1V 10Ah semi-solid battery (1100g) extended flight time from 16 to 24 minutes, a 50% increase. A 2026 northern inspection drone project replaced a 15.2V 6.7Ah battery requiring preheating with a 15.2V 10Ah -40°C low-temperature, 2C fast-charging battery, reducing charging time by 30 minutes and eliminating the need for preheating. A 2026 high-temperature drone project delivered a 22.2V 10Ah battery rated for 70°C operation, compared to the original -20°C to 60°C range.
Earlier cases show similar patterns: in 2025, an extremely fast/racing drone battery using pure cobalt lithium material and oily lamination reached a 400A discharge current; in 2024, a water rescue drone battery moved from 6S 7500mAh/50C at 1020g to 6S 6600mAh/15C at 810g, increasing flight time by 25%; and in 2019, an agricultural plant-protection drone battery reduced charging time from 50 minutes to 18 minutes through high-temperature electrolyte and ceramic diaphragm selection.
Certifications and Quality Assurance
Jentc’s OEM/ODM services are backed by global certifications including UL, CE, CB, and UN38.3, alongside dozens of patents accumulated over its 15 years of focus on high-rate battery customization. Its R&D team is described as covering the full stack from cell formula design through BMS hardware, embedded software, and communication protocol stack development.
A Customization Partner Built Around Scenario-Specific Engineering
Taken together, Jentc’s product matrix—covering high-rate batteries, drone batteries, semi-solid-state batteries, robot batteries, high-voltage lithium batteries, fast-charging batteries, high-temperature and low-temperature batteries, and supporting BMS systems—positions the company as an OEM/ODM resource for organizations whose drone or special-equipment power requirements fall outside standard product specifications. Industries served include agricultural plant protection, large-load drones, power and photovoltaic inspection, crossing drones, pipeline inspection, logistics, cleaning, and formation flight, as well as robots, robot dogs, laser equipment, and portable devices. For manufacturers evaluating a smart drone battery OEM/ODM partner, the combination of documented technical milestones, defined customization ranges, and case-by-case verified outcomes provides a factual basis for assessing fit against specific application requirements.
