Discover our high-precision smart BMS modules, custom battery protection systems, and portable power stations.
As global commerce transitions toward highly integrated smart ecosystems, consumer electronic components and mobile energy systems demand radical innovations. The traditional brick-like power bank is giving way to high energy-density, ultra-slim profiles designed for seamless enterprise, industrial, and consumer integration.
At Shenzhen Litongwei Electronic Technology Co., Ltd. (established in 2005), we recognize that structural slimness cannot come at the expense of safety. High-density thin battery cells require ultra-responsive, highly precise control architectures to mitigate thermal runaway risks, stabilize high current discharge rates, and protect longevity. Our deep capabilities in manufacturing both advanced lithium-ion safety control systems (BMS) and finished energy storage packs make us the primary OEM/ODM strategic partner for top tier global brands.
Our micro-energy management solution bridges the gap between hardware constraints and software control. By integrating intelligent algorithms with miniaturized, low-impedance protection boards, we deliver micro-profile structures that conform to international safety envelopes while scaling up to meet high capacity configurations.
A National High-Tech Enterprise Dedicated to Intelligent Lithium-Ion Safety Control Systems & Manufacturing Excellence Since 2005.
Established in 2005, Litongwei has evolved into a premier national high-tech enterprise focusing on the research, development, and manufacturing of state-of-the-art lithium-ion safety control systems. Over the last two decades, our components and solutions have powered everything from 3C digital products and personal mobile devices to complex industrial platforms including electric scooters, bicycles, motorcycles, tricycles, golf carts, automated guided vehicles (AGVs), agricultural drones, and professional-grade power tools.
We protect our clients' bottom lines by prioritizing intellectual property protection (joint patent developments to shield clients from infringement claims), developing industry-standard shared boards (slashing raw material costs and boosting integration efficiency), maintaining full-process digital traceability through our advanced MES system, and implementing remote diagnostic systems connected via custom cloud platforms.
A granular look at the technologies, materials, and engineering pathways designed to maximize energy density while ensuring absolute structural security.
By leveraging custom lithium polymer architectures infused with silicon-anode materials, our factory partners can achieve up to 800 Wh/L volumetric energy density. This allows us to manufacture wholesale ultra-slim power bank casings measuring as thin as 8.5mm, without sacrificing the structural integrity or nominal cycle life of the internal battery cells.
Litongwei is a pioneer in smart communication. We integrate microcontrollers with advanced firmware supporting Bluetooth, CAN, and RS485 communication protocols. Our BMS boards accurately report State of Charge (SoC), State of Health (SoH), and support localized custom safety profiles directly visible to consumer-facing mobile applications.
Supporting high-wattage power delivery (up to PD 140W in ultra-slim systems) requires maximizing conversion efficiency. Our high-frequency GaN charging designs reduce heat generation by 40% and keep transfer efficiency above 93%, preventing hot spots in slim power bank casings where space is constrained.
A history of pioneering technology, continuous capacity upgrades, and smart manufacturing integration.
Litongwei has maintained long-term strategic relationships with many of the world's most recognizable consumer electronics and battery cell manufacturers.
How our OEM factories support global procurement demands, industrial certifications, and diverse hardware deployments.
Our BMS boards (like the 20S 60A and 23S 60A series) are extensively optimized for light electric vehicles, golf carts, and e-bikes. Equipped with intelligent Bluetooth, CAN communication, and heating features, they safeguard high-drain vehicles working in low-temperature regions.
By using custom silicon-anode cells and miniaturized integrated circuits, we provide ultra-thin power bank shapes for custom distribution networks, promotional brands, and retail chains demanding small footprints and PD fast charging.
Automated manufacturing demands ultra-reliable power backup. Our smart protection boards monitor real-time battery status via our specialized cloud platform, avoiding unscheduled downtime and allowing automated guided vehicles to charge safely.
Sustained torque outputs rely on safe discharge dynamics. Our systems feature multi-tier protection (NTC thermal cut-off, overcurrent, and smart cell-balancing algorithms) to ensure cell longevity in harsh field operating conditions.
Sourcing from Chinese factories requires more than low prices; it calls for structural stability, compliance assurance, and protection against intellectual property infringement.
Intellectual Property Security: Litongwei enforces patent collaboration agreements with our buyers. By registering over 100 patents in circuit programs, tests, and BMS layout, we protect your private labels from infringement claims and market copycats.
MES Full-Process Traceability: Our Dongguan and Shenzhen plants employ real-time MES (Manufacturing Execution System) infrastructure. From raw silicon wafers and SMT mounting to final product testing, every batch is fully logged. You get completely trace-backed records showing the exact components and testing reports of your specific batch.
Global Certifications: We are certified in IATF 16949 (automotive grade quality management), ISO 9001, and ISO 14001. All finished products undergo strict CE, FCC, RoHS, and UN38.3 testing regimes to guarantee safe air and ocean shipping worldwide.
Honest answers regarding custom development cycle times, safety parameters, certifications, and wholesale quantities.
Achieving structural slimness requires three integrated protocols: first, we utilize High-Density Lithium-Polymer (Li-Po) cells which present higher dimensional stability than standard cylindrical cells. Second, our custom BMS limits the charge and discharge current dynamically based on continuous NTC temperature inputs. Finally, the structural frame of the power bank is reinforced with aluminum alloys and built-in expansion spaces to safely absorb standard battery gas emission cycles without deformed shell casings.
We support fully customizable parameter programming including: over-charge protection voltage (range 3.6V-4.28V), over-discharge protection voltage, overcurrent threshold, cell balancing start voltages, and temperature triggers via NTCs. Smart models can also be programmed with custom communication protocols (CAN/Bluetooth) to communicate directly with your unique devices or apps.
As a national high-tech enterprise, Litongwei has registered over 100 patents in circuit programs, BMS testing software, and structure design. We partner closely with our ODM/OEM clients, supplying legal patent documentation and technical layouts to ensure the product does not infringe on competitors' designs. This active patent shield is crucial for brands importing into high-compliance markets such as Europe and North America.
With our combined 40,000 square meters of production space across Dongguan and Shenzhen, and 24 high-speed placement machines, our monthly output exceeds 15 million PCBA/BMS units. For standard shared-board configurations, lead times average 14-21 days. Fully custom structural tooling and specialized ODM cell designs typically require 35-45 days from schematic approval to mass production shipment.
