Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is recognized as a national high-tech enterprise at the forefront of the research, development, and manufacturing of state-of-the-art lithium-ion battery safety control systems. Over the span of two decades, we have dedicated our engineering resources to addressing critical energy management challenges for international clients, designing tailored solutions across industries including 3C digital products, electric mobility (e-bikes, e-scooters, tricycles, and motorcycles), industrial machinery (golf carts, AGVs, robotics), unmanned aerial vehicles (drones), and heavy-duty power tools.
We pride ourselves on offering a multi-faceted commercial and technical framework for our partners. This includes comprehensive intellectual property protection (joint patent developments designed to safeguard your proprietary architectures), industry-standard shared board designs (driving cost down and production efficiency up), end-to-end MES product traceability for rigorous quality control, and advanced IoT-based remote cloud maintenance platforms. At Litongwei, we don't just supply components; we design integrated safety ecosystems that build long-term market value for your brand.
An in-depth exploration of how advanced Battery Management Systems determine the lifespan, safety, and efficiency of high-capacity energy storage installations.
In the landscape of modern renewable infrastructure, a lithium-ion battery system is only as reliable as its protection board (BMS). The primary point of failure in grid-scale energy storage, localized residential power walls, and high-drain mobility battery packs often traces back to inadequate thermal monitoring, voltage drift, or lack of transient overcurrent protection. As an industry-leading custom lithium battery energy storage manufacturer, Litongwei has optimized BMS architectures to mitigate these precise risks.
"A robust BMS does not merely cut off current during an emergency; it performs continuous real-time predictive state of health (SOH) and state of charge (SOC) modeling, actively balancing cells to prevent localized dendrite growth and potential thermal runaway events."
Depending on the load and series configuration, different battery packs demand tailored BMS topologies. Litongwei provides custom engineering for board architectures such as the LTW 13S 30A and 20S 100A systems. These protection boards integrate dedicated high-precision analog front-ends (AFEs) that monitor cell-level voltages to within ±5mV accuracy. Incorporating multi-channel NTC thermistors allows our BMS to suspend operations if temperatures exceed standard safe profiles, a critical feature for high-temperature settings or prolonged fast-charge cycles.
Our dual-factory strategy combines the high-tech prototyping resources of Shenzhen (13,000+ sqm) with the high-volume cost efficiency of Dongguan Huangjiang (27,000+ sqm). This integrated supply chain model allows us to control the entire manufacturing value chain—from incoming raw component validation to precision Surface Mount Technology (SMT) and final unit testing.
Equipped with 24 advanced high-speed pick-and-place (SMT) machines and 12 fully automated PCBA assembly lines, our factories process complex double-sided boards at pace, ensuring consistent solder joint quality and trace impedance. By housing all testing, thermal aging, and coating processes in-house, we eliminate intermediate logistic markups and dramatically compress turnaround times for OEM/ODM clients.
How we align with international electrical standards and safety certifications to guarantee frictionless deployment globally.
Navigating global regulatory landscapes requires a manufacturer with structured quality management. Over our corporate evolution, Litongwei has secured key industry milestones: achieving ISO9001 certification in 2007, ISO14001 environmental standards in 2009, and upgrading to the automotive-grade IATF16949 certification in 2018. These frameworks ensure that every protection board, micro-inverter, and energy storage accessory we manufacture meets strict design validation and verification guidelines.
To support high-reliability applications, we deployed a custom-tailored Manufacturing Execution System (MES). From the moment a component enters our Dongguan warehouse, its unique ID is scanned and tracked across every stage of the manufacturing timeline. If a field defect is reported, the MES traces the product back to its specific batch, production line, SMT machine, operator, and raw material supplier. This closed-loop traceability provides an invaluable layer of liability protection for global brands, ensuring consistent product performance and rapid diagnostics.
Our journey of innovation, expanding from basic digital battery management to pioneering Industry 4.0 energy systems.
Commenced intensive R&D on digital Battery Management Systems (BMS). Expanded rapidly into power battery management in 2006. Obtained ISO9001 in 2007, followed by ISO14001 certification in 2009.
Secured 8 utility model and design patents by 2011. Established the Litongwei Technology Research Institute in 2012. Honored with the Del New Energy Quality Excellence Award in 2014 and named Gold Partner by Gaogong Lithium Battery in 2015.
Upgraded quality systems to obtain IATF16949 certification in 2018. Deployed our custom warehouse automation and MES system. Awarded the Guangdong Battery Industry Association Innovation Award in 2019.
Deepened our software capabilities to integrate IoT and Industry 4.0 remote telemetry. Today, Litongwei drives digital transformation in high-voltage microgrid and utility-scale energy storage markets.
Decentralized generation and digitalized networks are transforming the way power is stored, converted, and distributed.
In urban European environments (most notably Germany, France, and the Netherlands), balcony solar systems have emerged as a dominant application. These residential setups utilize small PV arrays coupled with grid-tied micro-inverters. Because these installations sit in exposed exterior environments, they demand weather protection. Our LTWSmart Micro Inverter features an IP67-rated weatherproof housing, operates with 96.5% efficiency, and delivers clean, pure sine wave power, meeting strict localized grid compliance regulations across the European Union.
Industrial drones and automated guided vehicles (AGVs) operating in automated warehouses rely on high-discharge rates and rapid charging. Standard protection circuits cannot manage the sudden peak current demands of these systems. Litongwei's custom BMS with CAN communication provides precise, high-speed telemetry to the vehicle's central computer, ensuring safety during peak acceleration and preventing over-discharge during continuous operational shifts.
Electric scooters, bikes, and tricycles operating in high-density urban areas present unique safety profiles. Mechanical vibration, physical shock, and extreme temperatures can degrade battery connections. Our shared board platforms incorporate ruggedized component layouts, heavy-duty busbars, and conformal coatings that protect the underlying PCBA from moisture, dust, and mechanical stress.
We work closely with global tech brands to supply reliable, high-performance battery protection and conversion systems.
