Understanding the Custom Drone Battery OEM Landscape
Drone operators across agriculture, inspection, logistics, and defense-adjacent sectors consistently face a common set of obstacles: insufficient discharge capacity, limited flight endurance, slow charging, unstable performance in extreme temperatures, battery swelling, inconsistent cell performance, and inadequate energy density. For manufacturers and system integrators seeking a custom drone battery OEM manufacturer capable of solving these problems at the engineering level rather than through generic off-the-shelf products, Shenzhen Jentc Technology Co., Ltd. (operating under the brand names Jentc and Rechane) offers a full-stack customization model built around cell chemistry, battery management systems (BMS), and structural design.
Company Background and Strategic Focus
Established in 2011 and headquartered in Shenzhen, Jentc has spent 15 years focused exclusively on high-rate battery customization, with particular depth in drone batteries, semi-solid-state batteries, and the BMS systems that support them. The company's stated core values—Safety, Innovation, Quality—guide a business philosophy centered on "industry development as the guide, application technology as the cornerstone, and value enhancement as the mission." This translates into a service model where cell formula design, BMS hardware and embedded software development, and structural engineering are handled internally rather than outsourced, allowing Jentc to control the entire link from raw materials to finished battery pack.
The company's global certifications—UL, CE, CB, and UN38.3—support compliance requirements for international drone and equipment manufacturers, while a portfolio of dozens of patents underpins its formula and BMS development work.
Technical Milestones Relevant to OEM Buyers
For an OEM partner evaluating long-term technical reliability, Jentc's documented development timeline provides useful context:
- In 2015, the company introduced 4.35V high-voltage drone batteries (LIHV).
- In 2019, it launched an active battery balancing system (BMS) and a high-voltage version of a 3C fast-charging drone battery.
- In 2021, it introduced a 4.4V ultra-high-voltage large-capacity drone battery.
- In 2022, it released 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 intelligent management module and charger followed.
- In 2024, the company expanded into 400V high-voltage drone battery and charging solutions, high-current discharge high-speed drone batteries, and a -30°C to 10C low-temperature rate discharge drone battery.
- A drone battery intelligent instrument is planned for 2026.
This progression illustrates a consistent pattern: Jentc's product development follows what the company describes as an "Application Scenario + Innovative Technology" route, where real-world drone performance requirements drive each new battery or BMS release.
What Custom Drone Battery OEM Services Cover
Jentc's customized drone battery line is positioned to improve overall flight time and power performance. The differentiating approach rests on two pillars:
Cell-level customization. By selecting higher-performing positive and negative electrode sheets, electrolytes, separators, and conductive agents, and applying more advanced formulas and processes, energy density is increased, which directly extends flight time and improves power output.
BMS-level customization. A more reasonable SOC calculation and discharge logic addresses battery expansion and discharge failure risks, improving overall safety. Active balancing is used to maintain cell consistency, which extends cycle life.
The company's stated customization scope for drone and high-rate batteries includes: voltage up to 400V, discharge rate up to 180C, energy density up to 420Wh/kg, 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, along with complete BMS software and hardware solutions. These parameters are applied across agricultural plant protection drones, large-load drones, power and photovoltaic inspection drones, crossing drones, pipeline inspection drones, logistics drones, cleaning drones, and formation drones.
BMS Customization as a Distinct Service Line
Because many drone and specialized equipment applications cannot be served by standard battery management logic, Jentc offers BMS customization as a standalone service. This includes overcharge, over-discharge, over-current, short-circuit, and temperature protection as baseline functions, plus scenario-specific features such as a current-limiting function for flight (limiting current without triggering over-current cut-off), data collection for voltage/current/temperature, customizable single- or multi-protocol communication (CAN bus, Bluetooth), adjustable logic control, SOC/SOH calculation and feedback, active or passive balancing, automated fault-log recording for maintenance troubleshooting, and 4G-enabled remote monitoring for cloud-based visibility into battery pack status.

Evidence From Applied Cases
Jentc's project history includes documented outcomes across multiple drone categories. In a fishing drone application, a customer's 22.2V 6.5Ah ternary battery delivering roughly 16 minutes of flight time was replaced with a 23.1V 10Ah semi-solid battery of comparable weight, extending flight time to 24 minutes—a 50 percent increase. In a northern inspection drone and drone nest deployment, a 15.2V 6.7Ah battery requiring pre-flight warm-up was replaced 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. For a high-temperature drone operating environment, a standard 22.2V 10Ah cylindrical battery rated for -20°C to 60°C was replaced with a version engineered for 70°C operation using high-temperature electrolyte and modified pole-piece treatments.
In large-load and vertical takeoff and landing drone applications, an 88.8V 24S 10C 10Ah battery pack was redesigned using 4.4V ultra-high-voltage cells and optimized separator, copper foil, and conductive agent formulas, increasing capacity to 12,000mAh at 10C discharge while reducing pack weight to 5.8kg. This raised energy density by more than 25 percent and extended flight time from 5.5 minutes to 7.5 minutes, exceeding the customer's original expectation of 6.5 minutes. More recently, an underwater drone project required a 320V-class high-voltage pack with insulation detection, liquid-leakage detection, a master-slave BMS architecture, and waterproofing; the delivered solution used a semi-solid battery at 360Wh/kg energy density, configured as an 84S 50Ah pack with a 1-master, 3-slave BMS architecture communicating over CAN protocol.
Why Full-Stack Customization Matters for OEM Partners
For companies sourcing a custom drone battery OEM manufacturer, the practical advantage of Jentc's model is that cell chemistry, BMS logic, and structural packaging are engineered together rather than assembled from separate suppliers. This reduces integration risk and allows performance targets—flight time, charging speed, temperature tolerance, or discharge rate—to be addressed at the source rather than through workarounds. Jentc's semi-solid-state battery line, offering energy density up to 420Wh/kg and discharge rates up to 10C, extends this same customization philosophy to robotics, laser equipment, and other portable systems beyond drones.
Taken together, the company's 15-year technical history, certification coverage, and documented case outcomes provide a factual basis for evaluating Jentc as a specialized partner for drone battery and BMS customization projects requiring performance beyond standard commercial offerings.
