Explore our advanced catalog of lithium safety protection boards, smart communication displays, and IoT modules engineered to industrial tolerances.
In the modern era of Industry 4.0 and global electrification, the category of "accessories" has transcended basic structural or mechanical functions. Today, high-tier global enterprises view accessory management systems—particularly Battery Management Systems (BMS), wireless telemetry displays, and energy storage communications arrays—as the central nervous system of their consumer and industrial products. As a leading accessories manufacturer, Shenzhen Litongwei Electronic Technology Co., Ltd. serves as an indispensable technology partner, delivering functional safety, smart interconnectivity, and structural integrity.
From the bustling logistics hubs of North America using automated guided vehicles (AGVs) to grid-tied residential solar arrays across Western Europe, advanced accessories sit at the threshold of hardware optimization. Global supply chains mandate that manufacturers provide more than simple white-label designs; they require robust IP (Intellectual Property) mitigation frameworks, real-time performance logging, and zero-defect quality controls conforming to strict standards like IATF 16949.
"An accessory is no longer an afterthought. In modern hardware ecosystems, the integration of custom-designed safety circuit boards and telemetry controls is what differentiates market leaders from outdated systems."
Unpacking the technological advantages, scale efficiency, and quality-driven milestones of the Shenzhen-Dongguan electronics cluster.
With an independent 13,000 square meter facility in Shenzhen and an expansive 27,000 square meter plant in Dongguan Huangjiang, Litongwei scales to meet massive industrial volume. We house 24 high-speed pick-and-place assembly machines and 12 dedicated PCBA production lines, executing high-yield manufacturing runs effortlessly.
Sourcing from our factory provides intellectual property protection via structured patent collaboration. With over 100 patents in smart lithium-ion safety boards, circuit designs, and automated testing rigs, we collaborate with our clients to prevent market infringements and protect brand integrity.
We solve the "black box" manufacturing issue via our automated Manufacturing Execution System (MES). From raw component receipt (SMT placement) to multi-stage functional simulation testing, every single PCBA unit is serialized for full-process quality tracing and cloud platform diagnostics.
For nearly two decades, Litongwei has specialized in the R&D and production of lithium-ion safety control systems and intelligent electrical display boards. Founded in 2005, we have maintained a philosophy of "Technology as King, Efficient Service" to address technical, cost, and operational hurdles for our partners.
Our technology ecosystem comprises two core components:
Providing high-reliability, intelligent lithium protection boards from 1S up to 23S configurations. These solutions feature integrated communication options like CANbus, RS485, and Bluetooth, supporting active safety calculations, thermal heating components for low-temperature charging environments, and over-current protection configurations.
Developing display boards designed for large equipment, sightseeing vehicles, energy storage containers, and custom micro-mobility setups. These screens are engineered for clear data visualization under sunlight, extreme weather sealing, and direct system communication to support real-time user interaction.
A history of engineering excellence, certification milestones, and smart industrial automation growth.

Patent Expansion & Infrastructure: Secured 8 utility model patents by 2011. Established the Litongwei Technology Research Institute in 2012. Achieved the Del New Energy Quality Award and Partner status in leading lithium battery alliances.
Automated Smart Factory: Implemented the cloud-based MES manufacturing execution database. Earned IATF16949 automotive-grade certification in 2018. Honored with the Guangdong Battery Industry Innovation Award in 2019.
Smart Manufacturing+ & Industry 4.0: Advanced micro-mobility, ESS energy storage display interfaces, and micro-inverter designs. Scaling IoT integrations to support real-time data streaming and active cloud platform fleet management.
We design and manufacture high-performance accessories alongside leading global electronics brands.
Our partners include Huawei, Lenovo, Desay, Guoguang, Sunwoda, Eve Energy, Guoxuan High-tech, and other leading industry brands.
International standards for functional safety in hardware, such as UL 1973 for energy storage systems and EN 15194 for e-bikes, require battery packs to feature secondary safety protection. B2B procurement managers look for accessories manufacturers that can design and produce high-reliability, intelligent BMS hardware. Our customized 13S, 20S, and 23S boards address this need. With active communication protocols (such as CAN, RS485, and Bluetooth), these devices enable real-time tracking of cell voltages, temperature gradients, and state-of-charge metrics. This allows downstream operators to run preventative diagnostics, minimizing pack-level failures.
From warehouse AGVs to outdoor utility vehicles, human-machine interface (HMI) accessories must withstand challenging environments. Traditional, non-sealed components often fail due to moisture, mechanical vibration, or extreme temperatures. To address this, Litongwei manufactures heavy-duty, IP67-rated wired and wireless display screens. These units integrate directly into the vehicle's controller area network (CAN-bus), displaying battery health, error logs, and performance diagnostics under direct sunlight. This provides operators with immediate access to critical system data.
Decentralized energy distribution requires highly efficient conversion electronics. Standard central string inverters are vulnerable to single-point shading losses and high-voltage safety risks. In response, modern grid developers are utilizing micro-inverter accessories at the individual solar panel level. Our IP67-weatherproof micro-inverters offer 96.5% efficiency, maximizing energy yield from residential rooftops to commercial facilities while ensuring safe AC-voltage routing directly from the panel frame.
Hardware companies often encounter issues with mismatched component footprints and escalating engineering overheads. Litongwei addresses these challenges through a shared-board design program. By using shared topologies, we help clients reduce development and tooling costs. This approach standardizes core components across various product models, streamlining sourcing processes and shortening time-to-market.
Clear, technical answers to common queries regarding customization, manufacturing capacity, and regulatory compliance.
We hold over 100 patents in circuit topologies, safety programming, and automated testing. For custom ODM orders, we establish patent collaboration agreements that license our IP for your specific product designs. This approach helps protect your products from design infringement and potential patent disputes in Western and Asian markets.
Our intelligent protection boards support CAN, RS485, RS232, SMBus, and Bluetooth interfaces. This compatibility allows battery packs to share real-time cell metrics, thermal readings, and state-of-health data with vehicle controllers, telemetry units, or remote cloud monitoring platforms.
Our operations cover 13,000 square meters in Shenzhen and 27,000 square meters in Dongguan. Across these sites, 24 high-speed pick-and-place assembly machines and 12 PCBA production lines provide a monthly capacity of over 15 million units. This infrastructure allows us to easily scale to support large-volume product rollouts.
Yes. We offer smart protection boards equipped with integrated heating pad controls. When the temperature drops below zero, the board redirects charging current to the heating elements first. Once the battery pack reaches safe operating temperatures, charging resumes normally, protecting cells from lithium plating.
We maintain ISO 9001 and ISO 14001 certifications, alongside the automotive-grade IATF 16949 quality system standard. Our manufacturing processes utilize automated optical inspection (AOI) and digital MES tracking, ensuring complete process control for every batch we produce.
