Explore our high-performance electronic components, aerospace-grade connectors, and power storage modules manufactured under strict global standards.
Dynalink Electronic Technology Co., Ltd (DL), established in 2007, currently has a workforce of over 800 employees, among which more than 200 are technical staff. It is a technology-driven design and manufacturing company specializing in power supplies, energy storage capacitors, and connectors. With continuous investment in research and development and strong innovation capabilities, the company has built a complete industrial chain encompassing material research and development, product design, and precision manufacturing. Thanks to the advantages of high reliability and excellent performance, its products are widely used in key fields such as aviation, aerospace, shipping, railways, new energy vehicles, the medical industry, drones, and robots, providing customized solutions for customers.
As a leading supplier of energy storage and connectivity components, Dynalink's integrated value chain guarantees that the battery management systems (BMS), structural connectors, and capacitors used within our jump starter systems are produced in-house, ensuring unparalleled reliability, strict tolerance controls, and complete cost optimization.
The global portable power sector is experiencing a paradigm shift. Legacy lead-acid jump packs, long criticized for their heavy weight, rapid self-discharge rates, and poor performance in sub-zero temperatures, are rapidly being replaced by advanced lithium-ion and lithium iron phosphate (LiFePO4) chemistries. In commercial logistics, fleet management, and heavy automotive industries, high-rate discharge capabilities are vital. Modern high-discharge jump starter packs must supply instantaneous peak currents (often exceeding 3000A to 4000A) to turn over massive 12V and 24V diesel engines used in mining, maritime logistics, and transcontinental freight.
Additionally, the integration of ultra-capacitors (hybrid jump starters) is gaining traction. Ultra-capacitors capture residual charge from a weakened battery and release it in a concentrated burst, functioning almost independently of ambient temperatures. For bulk buyers, sourcing jump starters that feature smart BMS controls, spark-proof connection terminals, and reverse polarity safeguards is no longer optional—it is a critical safety and operational requirement.
B2B procurement professionals representing roadside assistance networks, agricultural machinery distributors, automotive retail chains, and municipal fleets face distinct challenges. Sourcing low-quality jump packs results in high return rates, cell swelling (bloating), and potential thermal runaway hazards. Industrial buyers demand comprehensive testing regimes, including UN38.3 transport certification, UL1642 cell verification, and CE/FCC compliance.
Furthermore, custom OEM and ODM needs dictate that supplier partners provide tailored housing options (high IP-rating dust and water resistance), custom cable lengths utilizing pure copper gauges (e.g., 8AWG or 4AWG), and integrated branding. Fleet operators also require multi-functional devices: jump packs that double as portable power stations, integrating high-output USB-C Power Delivery (PD) ports, 12V DC ports for auxiliary equipment, and built-in heavy-duty lighting systems.
The capability to reliably ship tens of thousands of high-rate lithium packs depends heavily on supply chain verticality. Dynalink leverages China's advanced Industry 4.0 infrastructure. Our smart factories integrate automated SMT (Surface Mount Technology) assembly lines, computerized battery cell testing, aging testing chambers, and precision CNC manufacturing. Because Dynalink directly manufactures critical components, including precision high-speed connectors, gold finger interfaces, and low-voltage energy storage capacitors, we remove intermediaries from the design loop.
This integration yields two key advantages:
1. Strict Quality Consistency: In-house production of connectors and capacitors avoids loose interfaces and voltage drop, preventing the hot-socket issues common in low-cost jump starters.
2. Compressed Lead Times: By controlling component pipelines, we buffer against global logistics fluctuations, ensuring consistent OEM/ODM deliveries even during peak demand cycles.
We do not just assemble parts; we manufacture the critical internal systems, offering end-to-end integration and custom development.
In the field of drones and automated mobile robotics (AMR), our high-rate discharge products ensure efficient, safe battery charging/discharging and robust power distribution system operations.
For high-density computing and data centers, our proprietary high-speed connectors and stable capacitor modules guarantee minimal transmission loss and unmatched long-term system reliability.
In harsh industrial settings, our high-protection connectors and heavy-duty capacitors provide stable electrical systems operating seamlessly in high-moisture or vibration-heavy environments.
Relying on our self-developed intelligent CAD/CAE modeling and design platform, we quickly process customer customization requests, delivering integrated prototype-to-production solutions.
Looking ahead, DL continues to invest heavily in solid-state battery R&D, ultra-high energy density capacitors, and precision high-amperage terminal systems to push the limits of power delivery.
Taking quality as our shield, we continuously optimize processes and standards to forge industry benchmark products. Dynalink structures its organizational excellence around three pillars:
OEM jump starter packs must operate reliably under diverse global conditions. Here is how Dynalink designs for regional environments:
Sub-zero temperatures drain traditional lithium cells of their voltage. Dynalink integrates internal self-heating thermal blankets and high-rate LiFePO4 cells that permit reliable engine cranking down to -40°C, a crucial feature for Canadian and Scandinavian heavy machinery fleets.
High ambient heat combined with engine bay heat risks thermal runaway. Dynalink uses flame-retardant V0-grade ABS housings, dual temperature sensors in the smart clamp circuits, and advanced cooling structures to operate safely up to +60°C.
Roadside assistance vehicles jump-start dozens of cars daily. They require jump packs with durable mechanical connections and quick recharge functionality. Dynalink's heavy-duty copper-alloy circular connectors and rapid 45W USB-C input circuits allow full recharge within 1.5 hours.
The company strictly complies with international standards and is fully certified under key quality frameworks, ensuring reliable industrial output.

For consumer vehicles, high-rate Lithium Cobalt Oxide (LiCoO2) is common due to high energy density and compact size. However, for industrial, fleet, and commercial operations, Lithium Iron Phosphate (LiFePO4) is preferred. LiFePO4 offers superior safety, thermal stability, and a longer life cycle (up to 2,000 charge cycles compared to 500 for standard lithium-polymer), making it ideal for tough warehouse and remote field conditions.
Traditional jump clamps can spark, drop voltage, or fail under high vibration. Dynalink designs and manufactures aerospace-grade circular electrical connectors and gold-finger socket connectors in-house. This guarantees tight physical connections, low contact resistance, and minimizes energy dissipation. These connectors integrate seamlessly with our BMS, triggering automatic shut-offs during reverse polarity, short circuits, or over-current situations.
To safely import battery packs, you must comply with shipping laws and regional standards. Mandatory requirements include the UN38.3 test report for lithium battery transport safety, plus MSDS (Material Safety Data Sheets). Depending on the market, you will need CE and RoHS certificates for Europe, and FCC or UL2743 certification for the United States.
Yes. Dynalink operates as a vertically integrated manufacturer. We provide comprehensive design services, including custom plastic injection tooling, specialized PCB/BMS layout, customized shell coloring, logo branding, and customized cables (high-gauge pure copper wire). We adapt jump pack designs to meet specific IP65, IP67, or IP68 water and dust ingress resistance requirements.
Standard lead times for bulk OEM orders range from 35 to 45 days after design sign-off and safety approval. Because we manufacture critical internal components, including capacitors and high-amperage connector plugs, in our own facilities, we avoid third-party component bottlenecks, offering stable shipping schedules year-round.
Every product undergoes a strict, multi-stage quality assurance process. This starts with testing raw incoming cells, followed by automated optical inspection (AOI) of the BMS board, x-ray weld checks, vibration stress testing, high/low temperature chambers, and a final automated cycle test. Our factories operate strictly under ISO 9001 and ISO 14001 management systems, guaranteeing traceable quality for every batch shipped.
Complementing our jump starter packs, we provide high-reliability capacitors and connection terminals for heavy transport, railway, solar, and industrial grids.
