Explore our custom intelligent power management systems, micro-inverters, and safety controllers configured for demanding commercial and industrial IoT applications.
The global landscape of the Internet of Things (IoT) has rapidly shifted from simple, low-power sensor networks to compute-intensive, real-time edge intelligence ecosystems. Today, Custom IoT Solutions act as the nervous system for smart factories, automated warehouses, electric micro-mobility networks, and utility-scale energy grids. As data processing demands escalate, the underlying hardware infrastructure must adapt.
A critical, yet frequently underestimated bottleneck in custom IoT applications is power stability and management. Unmanaged power delivery leads to system interruptions, data corruption, and catastrophic thermal incidents in Li-ion cells. As IoT nodes incorporate dual-band RF transceivers, high-performance edge controllers, and sensor arrays, they necessitate highly integrated, bespoke power safety layers that monitor state-of-charge (SoC), state-of-health (SoH), and system temperature in real time.
From field-level micro-mobility fleets to agricultural monitoring drones, engineers are demanding intelligent Battery Management Systems (BMS) that communicate via industrial fieldbuses (CAN Bus, Modbus, RS485) and wireless protocols (Bluetooth BLE, Wi-Fi, Zigbee). Our custom solutions address this paradigm shift, bridging the gap between raw hardware battery packs and digital cloud analytics platforms.
Understanding the complex design, compliance, and supply chain needs of multinational OEMs and IoT developers.
Global tier-one brands require components backed by comprehensive test reporting and manufacturing records. Ensuring IATF16949-grade quality and strict functional safety standards is mandatory to mitigate product liability and warranty failure claims.
Standard off-the-shelf boards do not support unique communication parameters. Custom IoT projects require firmware optimization to interface seamlessly with proprietary microcontrollers, IoT gateways, and telemetry units.
Outdoor hardware installations encounter extreme heat, moisture, and vibration. Custom IoT solutions must offer features like active heating layers for sub-zero temperatures and high IP ratings (IP67) to secure durable operating life cycles.
Modern procurement officers face significant risks when sourcing hardware. Choosing suppliers who lack high-volume manufacturing capabilities or deep engineering support leads to prototype-to-production failures. To mitigate these risks, procurement strategies are shifting toward vertically integrated suppliers who can handle hardware design, firmware development, PCB assembly, functional validation, and logistics under one roof. By integrating these processes, firms shorten time-to-market and ensure long-term availability of field components.
China's manufacturing sector has progressed beyond basic cost advantages to establish a robust ecosystem of technology innovation and supply chain resilience. At Shenzhen Litongwei Electronic Technology Co., Ltd., we combine strategic regional positioning with Industry 4.0 production principles.
Operating a 13,000-square-meter facility in Shenzhen and a 27,000-square-meter plant in Dongguan Huangjiang, our facilities utilize advanced automation systems. With 24 high-speed pick-and-place (SMT) machines and 12 PCBA production lines, we output over 15 million units monthly.
Our MES (Manufacturing Execution System) provides full-process traceability. Every component—from raw MOSFETs and IC controllers to the final protection board—is logged and tracked. This database-backed traceability system allows quick isolation of quality issues, protecting client brands and supporting field diagnostics for smart grid and automotive customers.
Analyzing the engineering parameters behind our smart battery protection algorithms and high-efficiency power conversion architectures.
As a designated national high-tech enterprise, Litongwei invests over 10% of annual sales back into R&D. This continuous investment drives our progress in battery safety, state estimation, and electrical topology design. Our engineering team focuses on three key areas:
We design systems up to 20S 200A that protect multi-cell lithium batteries from over-discharge, over-charge, and short circuits. Integrating Bluetooth, UART, CAN, and RS485 enables real-time parameters monitoring on mobile displays and custom industrial control panels.
Our proprietary heating-enabled BMS systems automatically warm up cold lithium cells during freezing temperatures. Combined with NTC thermal sensors, our systems ensure safe operation in sub-zero climates.
Our custom 500W-1kWh systems feature bidirectional DC-AC conversions for portable power stations, balancing energy flow with over 96.5% conversion efficiency to minimize thermal dissipation.
Built for balcony solar systems and outdoor energy nodes, our IP67 micro-inverters offer reliable performance under extreme weather conditions, supporting grid integration for residential smart microgrids.
Our patent portfolio contains over 100 registrations covering hardware topologies, cell-balancing algorithms, and automated test equipment designs. By collaborating with customers on intellectual property rights, we help minimize patent infringement risks when launching systems in North American, European, and Asia-Pacific markets.

Answers to common inquiries regarding battery management system customizations, production capacities, and integration services.
We customize protection parameters (over/under-voltage thresholds, overcurrent protection limits), board shapes to fit specific enclosures, communication channels (CAN, RS485, RS232, UART, Bluetooth, SMBus), and features like active heating layers or integration with external displays.
Our heating BMS uses built-in thermal sensors to monitor the battery temperature. If the temperature drops below a set limit (e.g., 0°C) during charging, the system routes the charge current through a dedicated heating pad. Once the temperature reaches a safe level (e.g., 5°C), the system switches back to normal charging.
Our factories in Shenzhen and Dongguan are certified to ISO9001 and ISO14001 quality and environmental management standards. Additionally, we hold the automotive-grade IATF16949 certification, which governs our design and production processes for vehicles, AGVs, and high-reliability systems.
With over 100 patents in circuit design, firmware, and test programs, we work closely with clients to mitigate infringement risks. We offer patent collaboration options, customized hardware designs, and private-label firmware to safeguard our customers' intellectual property in global markets.
Our micro-inverters reach a peak operating efficiency of 96.5%. Built with a rugged enclosure, they carry an IP67 rating, which protects against water submersion, high humidity, and dust in balcony and outdoor installations.
