Litongwei Electronic
Engineered for extreme performance, security parameters, and active balancing algorithms. Discover our flagship smart BMS series.
Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is recognized as a National High-Tech Enterprise at the forefront of engineering, designing, and manufacturing lithium-ion safety control systems and BMS. Our foundational architecture supports global 3C digital applications, electric mobility (scooters, e-bikes, and e-motorcycles), light electric vehicles (golf carts, AGVs), industrial drones, and complex energy storage solutions.
Operating across our highly automated facilities in Shenzhen and Dongguan, we address the critical pain points of hardware procurement: Intellectual Property Protection, Cost Optimization through Standardization, Total Traceability via MES software, and Remote Diagnostics powered by IoT systems.
How the shift to battery integration, wireless control, and IoT infrastructure shapes procurement priorities.
Standard lithium circuits are no longer sufficient. Modern consumer hardware demands Smart BMS technology equipped with Bluetooth, dynamic fuel gauges, and digital telemetry protocols (CAN bus, RS485, and UART) to report system state-of-charge (SOC) and state-of-health (SOH) parameters.
Thermal safety, overcurrent prevention, and reverse charging protection have shifted from secondary features to strict global compliance barriers. Custom configurations now integrate NTC heat sensors, automatic discharge-off safety logic, and mechanical isolation to meet global import laws.
Micro-inverters and compact consumer power banks represent the next wave of green energy integrations. High efficiency ratings (e.g., 96.5% MPPT micro-inverters) and IP67 weather-proofing are critical features for sustainable consumer electronics deployment.
Overseas procurement managers faces three core risks in custom electronics supply chains:
Litongwei neutralizes these bottlenecks by implementing automated quality checks and a strict component selection policy. We utilize only original, qualified power semiconductor parts and run multi-step Automated Optical Inspections (AOI) alongside comprehensive functional checks to deliver reliable, high-performance battery systems.
Explore the scale, equipment layout, and advanced engineering technologies supporting our high-volume production lines.
Our production capabilities are split across two core industrial centers: 13,000 square meters of space in Shenzhen and a larger 27,000 square meter manufacturing campus in Dongguan Huangjiang.
Equipped with 24 advanced SMT pick-and-place lines and 12 dedicated PCBA final assembly setups, our monthly capacity exceeds 15 million components to support fast, flexible delivery cycles.
Every single PCB, BMS, or inverter assembly is tracked from raw components to finished shipping crates using our customized MES software suite, guaranteeing complete manufacturing visibility.
Over 20 years of continuous growth, technological innovation, and engineering leadership in energy management.
In 2005, the company commenced R&D and manufacturing of digital Battery Management Systems (BMS). By 2006, operations expanded into high-power pack architectures. ISO9001 certification was obtained in 2007, followed by ISO14001 certification in 2009.
The company secured 8 utility model and design patents in 2011 while expanding its mobile power bank manufacturing operations. The Litongwei Technology Research Institute was established in 2012. It received the Del New Energy Quality Excellence Award in 2014 and earned the Gold Partner title from Gaogong Lithium Battery in 2015.
The company upgraded its ISO 9001 and ISO14001 certifications in 2016, achieved IATF16949 certification in 2018, and implemented an MES system for warehouse automation. It was awarded the Guangdong Battery Industry Association Innovation Award in 2019 and recognized as a leading brand in lithium battery protection board technology for two-wheeled vehicles in 2020.
Litongwei Electronics continues to innovate, deepening its technological expertise while embracing IoT and Industry 4.0. Through its Smart Manufacturing+ strategy, the company drives industrial transformation and upgrading.
Engineered specifically for extreme deployment environments, high current rates, and precise battery management.
Our smart 13S & 20S BMS series are deployed in thousands of electric scooters, cargo e-bikes, and e-motorcycles globally. Built-in Bluetooth allows riders and fleet operators to monitor battery temperature, cell voltages, and cycle history in real time.
Autonomous Guided Vehicles (AGVs) operating in 24/7 warehouse facilities require highly reliable batteries. Litongwei's heavy-duty 23S 60A and 100A protection boards feature smart balancing and CAN communications to support industrial machinery and tools.
From 1kWh portable energy stations with bidirectional inverters to IP67 micro-inverters for balcony solar systems, we deliver grid-edge hardware designed to safely manage domestic energy generation and storage.
Collaborating with global consumer tech leaders and industrial giants for safe energy storage solutions.
Our partners include Huawei, Lenovo, Desay, Guoguang, Sunwoda, Eve Energy, Guoxuan High-tech, and other major brand clients who have collaborated with us for many years.
Detailed technical insights regarding BMS integrations, inverter setups, and ODM production cycles.
Negative Temperature Coefficient (NTC) thermistors provide continuous temperature monitoring directly at the battery pack level. If the temperature exceeds safe parameters during rapid charge or high-load discharge phases, the BMS automatically cuts off power to prevent thermal runaway and protect the cells.
Integrating CAN/Bluetooth telemetry allows target hardware (such as AGVs, e-scooters, and storage displays) to query state-of-health (SOH), cell voltages, temperature, and cycle counts. This enables predictive maintenance, remote cloud diagnostics, and optimal system safety.
We offer co-patent development frameworks to protect our clients' custom designs. By establishing legal boundaries and securing design protections, we shield clients from patent infringement risks in overseas markets.
Our production lines operate under strict global quality standards, holding ISO9001 and ISO14001 certifications as well as automotive-grade IATF16949 certification. Our assemblies comply with CE, FCC, RoHS, and UN38.3 transport standards.
Standard hardware design reviews and prototype production are completed within 2 to 3 weeks. Full PCBA mass production typically takes 4 to 6 weeks, supported by our 24 high-speed SMT lines and comprehensive MES component tracking.
