High-performance components and energy modules engineered to meet strict mission-critical UAV requirements.
Modern unmanned aerial vehicle (UAV) systems require highly optimized energy architectures to balance weight, energy density, discharge rate (C-rate), and thermal stability. In the commercial and industrial drone markets, 4S configurations (4 Cells in series, nominal 14.8V or 15.2V for High Voltage variants) represent a sweet spot for medium-scale tactical, surveying, mapping, agricultural, and cinematic platforms.
For systems operating within the 12V to 16.8V voltage threshold, battery design must prevent internal cell impedance imbalance, manage rapid temperature spikes under high discharge currents, and guarantee accurate State of Charge (SoC) telemetry. Dynalink's ODM team leverages advanced silicon-anode and high-nickel cathode formulations to supply custom 4S lithium packs that increase mission endurance by up to 25% compared to standard off-the-shelf cells.
Established in 2007, Dynalink (DL) has developed into a technology-driven manufacturing enterprise. We specialize in custom high-rate power supplies, advanced energy storage systems, and precision electronic connectors. Operating with a workforce of over 800 employees—including more than 200 dedicated technical staff—we manage a complete in-house industrial chain that spans raw material formulation, structural design, BMS software development, and precision automated assembly.
Our engineering expertise serves highly demanding sectors including aviation, aerospace, marine shipping, new energy automotive systems, high-capacity industrial UAVs, robotics, and advanced medical diagnostics. Every custom cell assembly undergoes strict qualification testing to meet rigorous dynamic environmental profiles.

Reliable scaling capacities that support global drone OEMs from prototype validation to volume manufacturing.
How Dynalink's engineers design custom 4S Lithium batteries to maximize endurance, security, and integration.
We source and formulate cell structures capable of 30C continuous and 60C burst discharge phases. This prevents internal gas expansion and limits IR rise during intense maneuvers or heavy vertical climbs.
Equipped with native SMBus, I2C, and CAN-bus communication protocols, our custom BMS reads out active state parameters, monitoring precise voltage, remaining runtime, and overall cell health.
Our enclosures feature ultra-light thermal-resistant engineering plastics (UL94-V0 rated) combined with internal silicon potting. This offers robust dust, liquid, and vibration protection (IP67 compliant).
| Cell Configuration | Nominal Voltage | Energy Density | Recommended Applications | Standard Communications |
|---|---|---|---|---|
| 4S1P LiPo (Standard) | 14.8V | 180 - 210 Wh/kg | Industrial multi-rotors, cinematography drones, mapping rigs | SMBus / I2C / PWM |
| 4S2P LiHV (High Voltage) | 15.2V | 230 - 260 Wh/kg | Long-range surveillance UAVs, fixed-wing transit platforms | CAN-bus / SMBus |
| 4S3P Li-ion (Custom 21700/18650) | 14.4V | 250 - 280 Wh/kg | Light tactical UAVs, search & rescue, long-endurance patrols | Smart Telemetry / CAN-bus |
Integrating deep manufacturing capability with a reliable custom design pipeline to support complex projects.
Our high-rate 4S batteries ensure fast charging, reliable high-rate discharge stability, and robust connectivity with flight controller architectures.
From remote server data centers to industrial machinery, our precision electronic connectors and power systems ensure low insertion losses and reliable operations.
Engineered with high IP ratings and physical protection, our interfaces are designed to withstand vibration and dust in harsh working environments.
By utilizing our design platform, our technical staff rapidly drafts tailored cell layouts, BMS parameters, and enclosure configurations.
Engineered specifically to solve climate and operational constraints encountered in global markets.
Standard LiPo packs suffer from critical voltage drops in freezing conditions. Our custom 4S designs utilize integrated internal heating elements powered by the BMS. Before flight, the pack automatically self-heats to 15°C, ensuring full capacity release and avoiding sudden power loss in flight.
Sustained thermal exposure above 50°C accelerates internal cell degradation. Dynalink designs custom cooling channels inside the cell array, combined with custom phase change materials (PCM) to absorb heat, keeping peak cell temperatures below 60°C during heavy agricultural and surveying operations.
Saline atmosphere accelerates terminal corrosion. We package our 4S drone batteries in hermetically sealed cases with gold-plated connector terminals and high-grade silicone gaskets, achieving IP67 certification to resist salt-fog damage.
By operating our manufacturing facilities in China, Dynalink secures raw lithium stocks, executes precision cell match sorting, and performs high-speed automated packaging under one roof. Our modern factory tracks batch consistency down to single-cell internal resistance variances (≤ 1.5mΩ).
This integration bypasses external logistics delays, reduces overhead, and allows us to scale production from small batches to high-volume commercial contracts. Advanced automated aging testing verifies every batch's capacity retention across 500 charge-discharge cycles before final dispatch.
Dynalink's R&D focus is aimed at extending UAV flight times and enhancing energy safety profiles.
Developing 4.45V cell chemistries that boost energy density to 290 Wh/kg, allowing light-weight surveying drones to extend flight windows beyond 45 minutes on a single charge.
Transitioning production lines to utilize solid/gel electrolytes, significantly reducing thermal runaway risks while increasing mechanical puncture safety during missions.
Integrating Bluetooth and Ultra-Wideband (UWB) telemetry options to eliminate heavy wiring harnesses inside drone bays, reducing total pack weight by an extra 3.5%.
