Explore our core range of custom intelligent protection boards and micro-inverter series engineered for maximum power security.
Established in 2005, Shenzhen Litongwei Electronic Technology Co., Ltd. is a national high-tech enterprise specializing in the R&D and manufacturing of lithium-ion safety control systems. Over two decades of technical evolution, we have established ourselves as a premier global supplier of smart battery management systems (BMS).
Our products are widely utilized in 3C digital devices, electric scooters, electric bicycles, motorcycles, tricycles, golf carts, AGVs, drones, and high-power tools. By integrating proprietary hardware design with sophisticated cloud IoT configurations, we solve core industry issues like thermal runaway, cell imbalance, and high operational maintenance costs.
We provide intellectual property protection (patent collaboration), industry-standard shared boards for significant cost reduction, full-process traceability via custom MES, and remote cloud platform maintenance. Choose Litongwei to secure your power conversion systems and achieve unmatched field reliability.
Deep-dive into the specifications, topology, and parameters that govern 48V/51.2V LFP and Li-ion protection systems.
A 16S configuration is the industry standard for 48V (nominal 51.2V for LiFePO4) energy systems. Compared to 15S setups, 16S matches the charging voltage window of legacy lead-acid systems perfectly, rendering it ideal for direct drop-in telecom battery upgrades.
High-precision ADC chips capture cell voltages within ±1mV accuracy. NTC thermistors are strategically routed throughout the battery pack to capture localized hot spots, preventing thermal runaway via multi-stage firmware cut-offs.
While passive balancing burns excess cell energy as heat (30mA-150mA), our premium 16S BMS options feature active balancing topologies (0.6A-2A transfer current). This maximizes usable energy capacity and extends battery lifespans by up to 25%.
The architecture of lithium battery safety is transitioning from basic safety switches to cognitive, edge-computing nodes. Litongwei's technology roadmap highlights key developments that are shaping the future of global energy storage:
Through continuous iteration, our engineering team ensures that every wholesale customer receives products built for future regulations and energy density requirements.

Engineered for high reliability under harsh environmental conditions. Where we deliver robust safety controls:
Modern 5G telecom towers demand continuous high-discharge power backup. Our 16S BMS configurations support parallel battery pack operation up to 15-32 packs, with integrated RS485/CAN bus interfaces to easily upload battery telemetry to network operation centers.
Our smart 16S units integrate seamlessly with major inverter brands (Pylontech, Growatt, Victron, Goodwe). Built-in Bluetooth and mobile app monitoring give residential homeowners real-time insights into state of health, cell voltage deviations, and charge cycles.
Industrial automated guided vehicles (AGVs) and golf carts operate under high peak currents and mechanical vibrations. Our reinforced PCBA designs feature custom NTC placement and anti-reverse current paths, guaranteeing safety under tough physical stress.
Providing high-efficiency manufacturing capabilities and robust delivery cycles for global battery packs.
Our dual-production campuses in Shenzhen (13,000 sq. meters) and Dongguan Huangjiang (27,000 sq. meters) house 24 state-of-the-art high-speed assembly SMT systems alongside 12 automated PCBA testing lanes. Backed by fully digitized MES tracking software, every step—from paste deposition to final AOI validation—is archived to guarantee maximum reliability for bulk wholesale orders.
We work closely with leading global brands to provide reliable, high-performance battery systems.
Our partners include Huawei, Lenovo, Desay, Guoguang, Sunwoda, Eve Energy, Guoxuan High-tech, and other major industry clients with whom we've collaborated for years.
When sourcing 16S BMS systems at scale, global procurement managers look for several key technical and corporate qualifications to manage risk:
