From the first SMT placement of the protection circuit to final functional testing, enterprise procurement requires transparent documentation. Implementing MES (Manufacturing Execution System) infrastructure allows trace retrieval of each individual component, ensuring accountability for aerospace, automotive, and medical customers.
Power management hardware operating in tough environments must satisfy automotive reliability standards. Standard consumer-grade boards fail under constant vibration and thermal shock; selecting components manufactured on certified IATF 16949 production lines guarantees sustained operation in commercial vehicles, AGVs, and industrial tools.
Global operations place portable outlets in freezing field stations and scorching industrial plants. Advanced BMS circuits with built-in heating algorithms and multi-channel NTC sensors prevent charging below freezing points and cut off power during high-temperature spikes, avoiding thermal runaway.
The global manufacturing environment requires more than cheap production; it demands agile, automated, and deeply integrated facilities. Shenzhen Litongwei Electronic Technology Co., Ltd. operates state-of-the-art facilities in both Shenzhen (over 13,000 square meters) and Dongguan Huangjiang (27,000 square meters). These plants represent the peak of Industry 4.0 automation.
Equipped with 24 high-speed pick-and-place (SMT) machines and 12 PCBA production lines, our factories output over 15 million units monthly. This incredible volume is sustained by digital automation, where warehouse systems interface directly with our MES platform to monitor raw material usage in real-time. By minimizing manual handling, we achieve unmatched precision, keeping defective rates far below industry averages.
This localized supply cluster in the Guangdong-Hong Kong-Macao Greater Bay Area allows us to secure components, conduct rigorous QA testing, and package shipments with minimal lead times. For global enterprise clients, this translates to predictable delivery schedules, scalable production capacity, and superior pricing efficiency without compromising quality.
Custom portable power outlets and smart power systems optimized for specific industry needs.
Automated Guided Vehicles (AGVs) in smart warehouses need continuous energy. High-current protection boards (like the 20S 200A BMS with CAN/Bluetooth communication) ensure these automated machines recharge safely and operate without interruption.
Urban homes are turning into micro-generators. Integrating highly efficient, IP67-rated micro-inverters with balcony solar setups allows home-owners to convert DC solar energy directly into AC power, reducing grid reliance.
Critical biological shipments require temperature stability. Intelligent BMS units with integrated heating elements prevent batteries from dropping below safe charging thresholds, maintaining constant power to temperature-controlled systems.
From smart LED wearables to electric scooters and two-wheeled transport, lightweight energy storage solutions must endure physical impact, rain, and heat. Robust BMS protection ensures battery arrays remain safe throughout daily use.
Disaster response teams and field technicians rely on portable power banks (like our 500W / 1kWh power banks) to operate tools, communicate, and power telemetry equipment where grid infrastructure is unavailable.

Technical guidance and product support for global buyers and engineering teams.
Integrating communication protocols like Bluetooth and CAN Bus allows industrial operators to access real-time diagnostic data. CAN Bus provides robust, interference-resistant telemetry for electric vehicles (EVs) and heavy machinery, interfacing directly with vehicle controllers. Bluetooth allows field engineers to run diagnostic checks, adjust parameters, and view state-of-charge (SoC) details using a mobile app, minimizing maintenance downtime.
Lithium-ion cells charged below 0°C (32°F) suffer from lithium plating, which causes internal short-circuits and permanent cell damage. A BMS with a built-in heating algorithm uses the charge current to warm the heating element before allowing the cells to charge, protecting the battery in sub-zero environments.
Our micro-inverters achieve conversion efficiencies of up to 96.5%. By reducing thermal losses, they maximize usable battery capacity, minimize heating, and support stable power delivery to connected equipment.
Negative Temperature Coefficient (NTC) thermistors monitor thermal conditions at key locations across the battery pack. If temperature variance or a thermal spike is detected, the BMS shuts down current flow, preventing thermal runaway and protecting personnel and equipment.
We provide full-service customization support. Our engineering team designs custom PCB layouts, modifies software firmware protocols (CAN, RS485, Modbus), adjusts voltage/current limits, and co-develops enclosures to meet the requirements of your application.
