Pre-configured and thermal-optimized Battery Protection Boards engineered to perform in Thailand's tropical ambient challenges.
The Metropolitan Authority of Bangkok (BMA) is accelerating toward its bold target of zero carbon emissions. Anchored by the Eastern Economic Corridor (EEC) policies and Thailand's Board of Investment (BOI) incentives, Bangkok has transitioned into Southeast Asia’s central hub for electric vehicles (EVs), distributed solar energy, and industrial battery energy storage systems (BESS). However, operating high-capacity lithium-ion packs in Bangkok's tropical monsoon climate poses severe hurdles. Heavy rainfall, extreme relative humidity (frequently exceeding 85%), and ambient operating temperatures averaging 35°C call for far more than basic analog protection circuits.
Traditional hardware-controlled battery boards lack the dynamic algorithms necessary to prevent premature lithium aging and safe thermal management. This is where a Software-defined Battery Management System (BMS) becomes an indispensable technology. By leveraging cloud telemetry, real-time Bluetooth interfaces, and configurable serial protocols (CAN/RS485), our software BMS dynamically adapts charge curves, accurately assesses State of Health (SOH) and State of Charge (SOC), and triggers localized thermal balancing protocols—preventing safety risks long before they manifest.

Understanding the architectural distinction between basic hardware-based analog protection and intelligent software-driven systems.
Rather than using crude voltage lookup tables, our software BMS calculates State of Charge through adaptive algorithms. This provides a precision margin of <1.5%, preventing sudden power drops in heavy e-motorcycles on Bangkok’s streets.
Featuring low-energy Bluetooth (BLE) alongside serial interfaces (CAN 2.0B, RS485). Operators in Bangkok can monitor real-time cell differentials, cycles, and temperature parameters directly via localized Android/iOS applications.
Equipped with smart heating loops and NTC thermistor control. If cells dip during low-temp warehouse environments, or overheat during high-discharge operations in Bangkok’s summer heat, the software adjusts safety profiles dynamically.
Furthermore, our software BMS supports seamless **OTA (Over-The-Air) firmware updates**. As cell characteristics degrade over years of deployment, field operators in Thailand do not need to replace physical boards; safety thresholds and balancing algorithms can be optimized and deployed remotely via our cloud portal.

Urban micro-mobility in Bangkok experiences demanding duty cycles. Constant acceleration and rapid charging generates significant thermal stress. Our software BMS, like the 20S 120A or 23S 60A configurations, actively monitors individual cell temperatures. Through integrated Bluetooth and serial communications, fleet operations managers receive predictive alerts regarding battery health, protecting expensive assets and reducing down-time.
With Thailand's abundant solar radiation, factories across Bangkok, Samut Prakan, and Chonburi are deploying solar rooftop arrays paired with Battery Energy Storage Systems (BESS). Our high-capacity BMS boards ensure reliable cell balance across thousands of cycles, coordinating with industrial hybrid inverters via CAN communication to maximize solar ROI.
Thailand's telecom expansion demands uninterrupted backup power. Unreliable grid fluctuations must be mitigated by robust battery packs. Our BMS features smart same-port balancing and active diagnostic alarms, guaranteeing that telecom backup batteries switch on smoothly during outages.

Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is a recognized national high-tech enterprise specializing in the R&D and advanced manufacturing of lithium-ion safety control systems. Over the years, our products have served diverse industries including 3C digital devices, electric scooters, bicycles, motorcycles, tricycles, golf carts, AGVs, drones, and heavy power tools.
We believe in delivering holistic solutions that address our clients' core bottlenecks: Intellectual Property Protection (patent collaboration to mitigate design infringements), Industry-Standard Shared Boards (cost-efficiency and quick lead times), Full-Process Traceability (strict quality gates via our proprietary MES system), and Remote Maintenance (IoT Cloud Platform monitoring).
Litongwei works alongside leading global clients to drive the industrial green energy revolution, combining technological expertise with highly competitive manufacturing output.
Tracing our history from a specialized design house to a smart-manufacturing leader.
In 2005, Litongwei began R&D on digital Battery Management Systems (BMS). By 2006, we expanded into dedicated power battery management. We obtained ISO9001 certification in 2007 and ISO14001 in 2009, reinforcing our quality control foundations.
Secured 8 key utility model and design patents in 2011. The Litongwei Technology Research Institute was founded in 2012, driving innovations in mobile power and high-rate cell management. We won the Del New Energy Quality Excellence Award in 2014.
Upgraded our quality standards to IATF16949 certification in 2018. We implemented our automated MES system for warehouse and production traceability. Named the leading brand in lithium protection boards for two-wheeled vehicles in 2020.
We are executing our Smart Manufacturing+ strategy, merging IoT, cloud platform management, and automated surface-mount assembly lines to support clean-energy transitions in markets like Bangkok and Southeast Asia.
Litongwei is trusted by Tier-1 brands and OEMs across international consumer and industrial markets.
Procurement departments in Bangkok face the pressure of balancing safety, performance, and unit costs. By choosing Litongwei as your primary OEM/ODM partner, you tap into China's advanced electronics supply chain. With our dual production bases in Shenzhen (13,000 sqm) and Dongguan Huangjiang (27,000 sqm), we run 12 complete PCBA production lines and 24 state-of-the-art pick-and-place machines.
This allows us to maintain a monthly output of over 15 million smart protection boards. For Thai engineering and assembly operations, this translated to fast prototype turnarounds, stable batch quality, and direct shipping lines from Shenzhen port to the Port of Bangkok (Klong Toey) and Laem Chabang, utilizing RCEP tariff advantages for lower import duties.
