Industrial-Grade Battery Management Systems (BMS), Micro Inverters, and Smart Energy Solutions for Critical Global Infrastructure & Commercial Fleets.
Explore our custom intelligent BMS models, bidirectional portable power stations, and energy system hardware engineered for maximum safety and efficiency.
For procurement officers, supply chain managers, and global engineering heads, sourcing lithium-ion battery solutions extends far beyond cells and capacity numbers. Today's commercial, industrial, and municipal energy sectors demand robust, intelligently governed power ecosystems. The core challenge of modern energy storage lies in the safety control architecture—specifically, the Battery Management System (BMS).
As international supply chains experience intense regulatory shifts, corporate buyers prioritize manufacturers that offer high regulatory compliance, robust IP protection, and advanced predictive health diagnostics. At Shenzhen Litongwei Electronic Technology Co., Ltd., we tackle these demands directly, engineering safety systems that safeguard both operational ROI and physical property across diverse operating environments.
Integrating digital safety architectures with field operations across multiple commercial and industrial sectors.
We design high-vibration resistant BMS configurations for two-wheeled vehicles, AGVs, golf carts, and material handling systems. Our systems utilize active thermal protection, integrated NTC sensors, and real-time state-of-charge tracking to prevent premature thermal thresholds under heavy loads.
With systems like the LTWSmart Micro Inverter MINV500S, we enable decentralized grid-tied energy systems. Delivering a peak conversion efficiency of 96.5% and built to IP67 weatherproof standards, these modules allow residential and light commercial users to safely and efficiently harvest balcony solar energy.
High-discharge applications demand ultra-low internal resistance profiles. Litongwei's custom 10S to 23S protection boards manage continuous current limits up to 200A. They include integrated temperature switches and localized balancing networks to prevent single-cell overstressing.
Moving beyond basic overvoltage protection, the future of smart energy management relies on edge-computing BMS hardware and cloud diagnostics.
Traditional passive balancing dissipates excess energy as heat, lowering overall pack efficiency. Litongwei's advanced BMS modules feature intelligent balancing networks. They redistribute energy between adjacent cells during charge and discharge cycles, extending overall pack life cycles by up to 20%.
Modern battery packs operate within complex digital systems. Our smart BMS models feature native support for CAN, RS485, and Modbus protocols. This allows systems to connect with microinverters, central computers, and vehicle control units for seamless diagnostics.
Our BMS units connect with wireless telemetry options, including Bluetooth and local IoT gateways. This enables operators to upload live cell statistics (SoC, SoH, temperature logs) to cloud servers. System health checks and firmware updates can then be managed remotely, minimizing onsite maintenance costs.

From our origins as a dedicated BMS design house to our growth into a leading global supplier of smart energy systems.
Litongwei commenced R&D and manufacturing of digital Battery Management Systems (BMS) in 2005. We expanded into power battery management system development in 2006, securing ISO9001 certification in 2007 and ISO14001 certification in 2009.
We secured 8 utility model and design patents in 2011 while expanding our mobile power bank operations. In 2012, we founded the Litongwei Technology Research Institute. Our innovations earned us the Del New Energy Quality Excellence Award in 2014 and the Gaogong Lithium Battery Gold Partner title in 2015.
We upgraded our ISO9001 and ISO14001 certifications in 2016 and achieved IATF16949 certification in 2018. During this period, we implemented an automated MES system to optimize warehouse management. We were honored with the Guangdong Battery Industry Association Innovation Award in 2019 and named the leading brand in lithium protection board technology for two-wheeled vehicles in 2020.
Litongwei continues to innovate, deepening our technological expertise while embracing IoT and Industry 4.0. Through our Smart Manufacturing+ strategy, we drive industrial transformation and upgrading across all energy storage lines.
We collaborate with global consumer electronics brands, vehicle manufacturers, and key energy enterprises to power the future.
Answers to common technical, manufacturing, and integration inquiries from procurement managers and electrical engineers.
Litongwei focuses on high-precision monitoring, advanced thermal management, and robust EMI/EMC design. Our systems feature multi-point temperature monitoring (NTC), high-side drive architectures, and integrated communication protocols (CAN/RS485/Bluetooth). These elements ensure steady performance in demanding applications, including light electric vehicles and industrial power systems.
Our active balancing architecture dynamically redistributes charge from higher-voltage cells to lower-voltage cells within the pack. Unlike passive systems that waste excess energy as heat, our design preserves energy, reduces hot spots, and balances the pack to maximize operational capacity.
