How DL is defining the next generation of portable starting power and intelligent emergency charging systems through active chemical innovations.
Traditional lithium-ion batteries pose severe thermal runaway risks under extreme impact or mechanical deformation. DL is pioneering the engineering architecture of solid-state polymer electrolytes inside our portable jump starter boxes. By replacing liquid volatile solvents with non-flammable solid ion conductors, we elevate safety while achieving an energy density exceeding 380 Wh/kg, ensuring robust engine cranking power even under physical battery compromise.
For operations in sub-zero climates down to -40°C, chemical batteries experience severe kinetic impedance. DL's technology roadmap integrates our proprietary self-healing impulse capacitors in parallel configuration with high-discharge rates lithium-ion packs. The hybrid design enables instant pulse power delivery of up to 4000 Peak Amps, drawing remaining residual charge from weak vehicle batteries to jump-start the engine within 2 seconds without depleting the core battery pack.
Future emergency power banks require predictive state-of-health (SoH) diagnostics. Through our AI-driven software architecture, the built-in microcontrollers execute continuous algorithms monitoring cell impedance, voltage balance, and localized temperature rises. Built-in Bluetooth and IoT transceivers feed telemetry data to fleet managers, offering seamless battery status visibility for commercial operations.
Engineered to operate in the harshest environments. Our solutions empower global infrastructure, emergency response fleets, and automated industries.
Providing high-rate discharging batteries that support swift field deployment. In tactical UAV missions, our battery management solutions guarantee stable high-current peaks for takeoff sequences and reliable emergency reserve power in sub-zero high-altitude deployments.
Delivering custom-designed, heavy-duty jump start boxes optimized for commercial delivery trucks, heavy-duty logistics transport, and utility service vehicles. Incorporating active thermal heating systems to prevent performance loss during winter.
Our heavy-duty starting boxes are designed to output thousands of cold cranking amps for massive earthmoving equipment, agricultural machinery, and backup systems for manufacturing processes operating in highly contaminated areas.
Our digitalized factory floor leverages automation, continuous quality tracking, and vertical integration to provide superior reliability and cost efficiency.
We don't just assemble off-the-shelf components. DL designs and manufactures the critical components in-house: from robust, high-protection multi-pin connectors to impulse capacitors. This ensures unmatched quality control and immune-to-disruption delivery schedules.
Our Manufacturing Execution System (MES) records every solder paste thickness, lithium battery sorting metric, and screw tightening torque. Robots handle cell pairing to achieve millivolt-level consistency across battery modules, preventing premature failure.
Every batch of portable jump start boxes undergoes intensive environmental validation. This includes thermal cycling chambers (-45°C to 85°C), multi-axis physical drop testers, high-pressure water ingress tests, and simulated short-circuit stress tests.

We believe in post-sale integration support. DL supports localization networks with technical service centers in Europe and North America, offering rapid warranty exchanges, technical failure analysis, and replacement parts dispatching to maintain supply-chain integrity.
Our systematic manufacturing processes are certified to meet international standards for quality, environment, and occupational safety.
In-depth, engineering-level answers regarding battery safety, peak current calculations, and customized ODM/OEM processes.
Safety is managed at three distinct architectural levels. First, we use premium LiFePO4 and high-density cobalt formulation cells paired with ceramic coated separators that resist temperatures up to 150°C. Second, our custom-designed BMS system provides hardware-level over-charge, over-discharge, short-circuit, and reverse-polarity protections with millisecond response. Finally, our structural designs incorporate structural heat dissipation plates and shock-proof rubber mountings to prevent mechanical impact damages.
Peak current refers to the absolute maximum transient current output the battery and circuitry can handle for a split-second (typically under 100 milliseconds) without destroying components. Starting current (or cranking current) represents the sustained power the jump start box delivers over 2 to 5 seconds to actively crank the engine. When procuring ODM systems, specifying the actual displacement of targeted vehicle engines (e.g., 8.0L Gas / 6.0L Diesel) is critical to determine the correct required cranking current.
Yes, we design and produce custom heavy-duty enclosures utilizing double-injection molding (ABS+TPU) with precision silicone sealing gaskets. We also apply conformal coatings to internal printed circuit boards (PCBs) to guarantee long-term resistance to corrosion, moisture, and fine metal dusts in industrial environments.
For custom ODM modifications (including custom battery configuration, branding, and shell variations), the typical MOQ starts from 500 to 1000 units depending on complexity. Tooling and initial prototyping usually take 35 to 45 days, followed by mass manufacturing runs of 30 to 45 days after prototype sign-off.
To overcome chemical inertia in extremely cold climates, our premium units can be equipped with integrated heating pads powered by the battery pack. Upon activating the device, the internal BMS warms the cells to optimal temperature zones (above 0°C) before initiating high-current discharging, protecting the internal cell structure from damage and maximizing crank energy efficiency.
For our high-precision floating series and VPX slot backplanes, we employ high-speed CCD visual inspection cameras and specialized pin insertion force testers. This ensures zero defects on pitch alignments and uniform contact resistance on gold-plated pins, preventing transmission dropouts in high-vibration aerospace and railway applications.
