Direct manufacturer supply chains featuring high-efficiency micro-inverters, multi-series intelligent BMS, and advanced smart interfaces designed for residential and smart-grid ecosystems.
We are a national high-tech enterprise specializing in the R&D and manufacturing of lithium-ion safety control systems. Over two decades of rigorous development has built our reputation as a trusted manufacturing partner for global smart home and grid energy brands.
Our advanced battery management systems (BMS) and intelligent grid solutions are widely used in 3C digital devices, electric scooters, bicycles, motorcycles, tricycles, golf carts, AGVs, drones, and heavy-duty power tools. By offering IP protection, collaborative patent support to prevent infringement, industry-standard shared boards for cost reduction, full-process MES quality traceability, and remote IoT cloud maintenance platforms, we solve critical technical, operational, and financial challenges for global scale operations.
Combining heavy infrastructure investment with rigorous intellectual property mechanisms to ensure robust supply solutions.
With an expansive 13,000 square meters of independent manufacturing space in Shenzhen, complemented by 27,000 square meters of production facility in Dongguan Huangjiang, we operate 24 high-speed SMT assembly lines and 12 dedicated PCBA process lines, generating over 15 million units monthly.
We allocate more than 10% of our annual gross sales revenue directly into research and development. This commitment sustained over five consecutive years has empowered us to lead industry innovations in safety controls, power optimization, and multi-protocol smart home energy integrations.
Holding over 100 patents in lithium battery protection board design, automation structures, and software test utilities. Our patent portfolios protect our global brand clients from cross-border intellectual property disputes and local patent infringement complaints.
Unveiling the convergence of edge intelligence, clean energy, and interoperable smart home ecosystems.
The fragmentation of the smart home sector is fading. Our technology map focuses on native compatibility with Matter and Thread protocols, assuring seamless local control, faster response times, and plug-and-play capability across Google Home, Apple HomeKit, Amazon Alexa, and Samsung SmartThings systems.
Integrating micro-inverters with smart BMS allows neural-network controllers to analyze real-time home energy demands, weather forecasts, and grid pricing patterns. Smart home systems autonomously optimize battery storage schedules and discharge cycles to maximize home efficiency while minimizing energy expenses.
Future smart home control structures will process safety calculations directly at the device edge. Utilizing local microcontrollers (MCUs) inside BMS boards allows quick response to power spikes or overheating, isolating battery faults locally within 10 microseconds to protect the entire home infrastructure.
Our products serve as the foundational infrastructure for modern high-efficiency home environments, urban transport networks, and commercial off-grid developments.
By pairing our IP67-rated micro-inverters with high-stability lithium battery packs and customized display units, we allow rapid deployment of plug-in solar arrays on European balconies, offering grid-synced power generation.
Providing CAN/RS485-enabled BMS to e-bike and e-scooter fleet sharing companies. This guarantees real-time telematics tracking, predictive maintenance reports, and battery pack status updates over IoT cloud configurations.
Industrial battery management modules tailored for remote telecom towers and emergency infrastructure. Equipped with high-amperage heat management matrices to withstand environmental hazards.
"LITONGWEI has always adhered to the philosophy of 'Technology as King, Efficient Service' in all aspects of production and operations. Our vision is to become a provider of intelligent green energy management solutions, embracing environmental sustainability. Start with LITONGWEI!"
Harnessing Shenzhen's advanced technological cluster and Dongguan's manufacturing scale to deliver competitive benefits.
Every single PCBA and BMS component leaving our assembly line is logged into our manufacturing execution system (MES). Every critical step, from SMT placement and reflow profile monitoring to AOI inspections and load-bank validation, is tied to a unique barcode. This ensures long-term field stability and allows swift diagnostics in case of device failure.
By manufacturing for various sectors—including 3C digital, electric micro-mobility, drone energy, and grid energy storage—we negotiate raw component pricing with top-tier silicon and passive element vendors, insulating our partners from extreme price swings and material shortages.
Addressing the complex technical and supply chain challenges faced by procurement departments and B2B distributors.
Global corporations must protect their designs. Litongwei provides custom-tailored design configurations, isolating unique intellectual properties and offering legal patent cooperation to secure distribution rights in sensitive jurisdictions like Europe and North America.
To support younger companies, we offer standardized shared board structures. These pre-certified modules help brands bypass expensive tooling costs, allowing immediate prototype builds and faster market release at lower cost.
For large-scale deployments, managing remote updates can be challenging. We integrate specialized communications protocols (Bluetooth, CAN, RS485, and Wi-Fi modules) to allow remote debugging, reducing post-sale service expenses.
Entering new global markets requires adhering to strict regulatory certifications. Litongwei provides certified systems that meet international safety, environmental, and communications guidelines.
Compliance with UL 1973, UL 9540A, CE, FCC, and RoHS standards.
UN38.3 test report and MSDS paperwork for safe sea and air shipping.
Collaboration with regional centers to offer swift local technical service.
Comprehensive IATF 16949 automotive-grade production system audits.
Modern smart home environments interact closely with regional electrical grids. Our LTWSmart Micro Inverters feature advanced grid-disconnection protocols, complying with European VDE-AR-N 4105 grid safety standards.
This features integrated islanding prevention, meaning that if local utility grid power goes offline, our inverter shuts off generation within milliseconds, preventing hazardous feedback into the local lines to protect line maintenance workers.
