Explore our foundational safety control boards, Bluetooth-enabled Smart BMS, and bidirectional portable power storage units built for rigorous industrial applications.
In the contemporary industrial and manufacturing ecosystem, safety equipment has transcended basic physical wear to include highly sophisticated electrical protection systems. As electrification sweeps through critical global infrastructures—from warehouse automation (AGVs) and micro-mobility networks to off-grid solar storage arrays—protecting power modules from thermal runaway, electrical overloads, and unexpected cell deterioration has become paramount.
Global safety regulations (such as UL 2580, IEC 62619, and UN38.3) dictate that electronic safety control units, especially Battery Management Systems (BMS), act as the primary defense mechanism. A malfunction at this level can lead to catastrophic consequences, including fire hazards, property destruction, and system-wide downtime. Consequently, international procurement teams now demand custom safety solutions engineered to operate reliably under extreme conditions, including wide-temperature environments and high-vibration applications.
Shenzhen Litongwei Electronic Technology Co., Ltd. addresses this vital industrial demand. By pioneering custom smart boards featuring advanced heating capabilities, communication protocols (CAN/Bluetooth/RS485), and real-time sensor telemetries, we protect modern electrical infrastructure and ensure compliance with strict international safety directives.
Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is a national high-tech enterprise dedicated to the R&D, design, and manufacturing of lithium-ion safety control systems. Over nearly two decades, we have developed solutions that empower global supply chains to run safer and more efficiently.
Our specialized products are deployed across a broad range of sectors: 3C digital devices, electric scooters, smart electric bicycles, electric motorcycles, utility tricycles, golf carts, automated guided vehicles (AGVs), delivery drones, and high-performance power tools. By maintaining strict control over components and circuit topologies, we deliver critical protective control boards that prevent short-circuits, overcharging, and thermal instability.
We pride ourselves on offering complete operational support to our clients through four core value pillars:
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!
Why industrial procurement teams leverage our regional supply chain clusters for bespoke electronic safety boards.
Situated in the heart of China’s electronic manufacturing hubs (Shenzhen and Dongguan), we source components and establish custom tooling setups within days, not weeks. This accelerates the path from proof-of-concept (POC) to production-ready safety systems.
Equipped with 24 high-speed placement machines across 12 automated PCBA production lines, our manufacturing floor eliminates manual placement errors. Every single safety board undergoes automated optical inspection (AOI) to secure absolute structural integrity.
We deploy an advanced Manufacturing Execution System (MES). This assigns a unique digital ID to every component batch and board. If a failure is reported in the field, we can trace it back to the specific wafer, production line, time stamp, and testing log.
Where Litongwei safety equipment systems prove their resilience globally.
Automated Guided Vehicles operating 24/7 in smart warehouses cannot afford safety shutdowns. Our 20S 100A/200A BMS featuring NTC thermal sensors and intelligent balance networks monitor high-drain battery arrays. They prevent excessive heat buildup during rapid charging cycles, maintaining logistics floor productivity.
Lithium-ion chemistries degrade and fail if charged in freezing temperatures. Our smart safety protection boards feature integrated heating circuits that safely warm cells to optimal temperatures before allowing charge inputs. This is essential for off-grid communication stations and solar towers in high-altitude environments.
Electric scooters, golf carts, and electric cycles navigate high shock and vibration environments. We design physically reinforced PCB layouts with rugged trace lines and solid-state safety circuits. These systems prevent internal solder fractures and safeguard riders from potential thermal issues.
A proven track record of reliable capacity, consistent R&D dedication, and protected intellectual property portfolio.
Our manufacturing network spans two high-volume plants: over 13,000 square meters of independent manufacturing space in Shenzhen, and an additional 27,000 square meters in Dongguan Huangjiang. Equipped with 24 high-speed pick-and-place assembly machines and 12 state-of-the-art PCBA production lines, our monthly output reaches over 15 million units.
We are a technology-first company. Over the past five consecutive years, we have systematically reinvested more than 10% of our annual sales revenue directly back into our research and development divisions. This ongoing investment fuels the next generation of smart safety control systems and BMS software integration.
We secure your market advantage. Litongwei holds over 100 patents in the lithium-ion battery protection board space, as well as multiple software copyrights for circuit testing and industrial automated calibration. We offer joint patent collaboration projects to mitigate patent infringement risks for OEM/ODM products worldwide.
