Field-tested intelligent battery protection boards designed for high thermal stability and direct communication protocols.
Addressing thermal safety, high altitude challenges, and industrial grid compliance across the Bajío and northern industrial corridors.
Mexico's manufacturing sector is undergoing an unprecedented expansion driven by nearshoring. Automotive assembly lines, logistics hubs, and high-tech manufacturing plants are consolidating in states like Nuevo León, Querétaro, and Coahuila. This shift demands reliable energy backup systems, electric AGVs (Automated Guided Vehicles), and large-scale Battery Energy Storage Systems (BESS) to buffer grid inconsistencies.
At the heart of these battery storage solutions is the Hardware Battery Management System (BMS). As an essential component for system protection, the hardware BMS prevents catastrophic failures such as over-charging, thermal runaway, and localized cell imbalances that can interrupt 24/7 manufacturing plants.
Urban transit in Mexico City (CDMX) and Guadalajara is rapidly shifting towards micro-mobility (electric cargo bikes, e-scooters, and electric delivery trikes) to circumvent severe traffic congestion and reduce particulate emissions. Operating these fleets in variable terrains requires custom BMS units capable of handles high transient discharge currents and operating efficiently at elevations exceeding 2,200 meters.
Additionally, remote agricultural regions in Sonora and Chihuahua are adopting solar microgrids to supply uninterrupted power. These microgrids rely on robust LiFePO4 batteries managed by advanced BMS boards that communicate environmental and electrical telemetry back to regional operators via Modbus or IoT systems.
Discover the engineering standards behind our hardware architectures that guarantee longevity and safety under load.
Modern industrial energy systems cannot operate as black boxes. Our BMS boards support CAN 2.0B, RS485 Modbus RTU, and integrated low-energy Bluetooth. This facilitates real-time monitoring of SoC (State of Charge), SoH (State of Health), and individual cell voltages directly from central control units or mobile applications.
To withstand northern Mexico's desert temperatures exceeding 45°C, and high-altitude drop-offs in central Mexico down to 0°C, our architectures incorporate dual-channel Negative Temperature Coefficient (NTC) thermistors. The hardware initiates a charge disable state below 0°C to prevent lithium plating and a thermal cut-off above 65°C.
Differences in internal resistance among battery cells can degrade system lifespan within a year. Our hardware features precise balance control circuits (30mA to 100mA balancing current options) that automatically dissipate excess charge from higher-voltage cells during the top charge phase, ensuring uniform wear across the pack.
Engineered BMS implementations customized for local regulatory compliance and extreme environmental operation.
For electric delivery fleets operating in high-density urban environments, battery packs undergo high-vibration stresses and heavy charge-discharge cycles. We supply customized 13S to 20S smart BMS systems equipped with solid-state conformal coatings to protect the electronics against moisture and dust ingress (IP65/IP67 rated). The integration of Bluetooth communication allows delivery operators to scan vehicle battery status instantly without removing mechanical panels, reducing fleet diagnostic downtimes by 40%.
In Mexican solar installations, energy storage acts as a grid buffer. Our high-current 100A to 200A BMS boards support parallel system configurations, allowing modules to communicate seamlessly. With integrated CANbus lines, these systems sync with popular low-voltage and high-voltage hybrid inverters to prevent overcurrent spikes during cloud transitions.
Data centers in Querétaro require ultra-reliable battery backup systems. We engineer 15S and 16S LFP protection boards featuring remote hardware reset capabilities and low stand-by current usage. When the power grid operates normally, the BMS draws less than 100µA, minimizing self-discharge during long standby durations.
A trusted national high-tech enterprise driving advancements in battery management safety since 2005.
Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. (LTW) is a premier national high-tech enterprise dedicated to the research, development, and high-volume manufacture of lithium-ion safety control systems. Over nearly two decades, we have scaled our operations to support a wide range of battery packs used in 3C digital devices, electric scooters, e-bikes, motorcycles, golf carts, automated guided vehicles (AGVs), drones, and portable power tools.
We pride ourselves on offering four distinct value pillars to our global customers: intellectual property protection (cooperative patent protection to prevent infringement), industry-standard shared boards (maximizing cost-reduction and production efficiency), full-process digital traceability (through our integrated MES factory automation), and remote cloud maintenance.

Combining state-of-the-art automation and massive scale to guarantee competitive lead times to the Americas.
To support fast-paced delivery schedules required by Mexican custom clearances, our manufacturing operations are split across high-efficiency hubs. The Shenzhen site hosts over 13,000 square meters of high-density assembly lines, while our Dongguan Huangjiang campus expands across 27,000 square meters.
Our lines are equipped with 24 high-speed pick-and-place SMT machines and 12 dedicated PCBA production lines, giving us a massive monthly capacity exceeding 15 million units. This high level of automation drastically minimizes the human error margin and maintains unit consistency across tens of thousands of pieces.
We implement a full MES trace protocol. Every board has a unique laser-etched matrix barcode linking back to its original raw silicon batches, component assembly time, reflow oven temperature profiles, and final automated optical inspection (AOI) data.
For our Mexican partners, this level of traceability mitigates operational risks and provides clear audit documentation for compliance with NOM and safety inspectors.
