Explore our diverse portfolio of high-efficiency lithium battery packs and related solar components engineered for global enterprise applications.
Understanding the shift from legacy lead-acid systems to highly integrated, safe, and long-lasting 4.8kWh nominal lithium-ion blocks.
In modern industrial design, 48V DC has emerged as the global standard for low-voltage power distribution. Systems built around 48V optimize the delicate balance between electrical safety and distribution efficiency. By utilizing a 48V nominal voltage (typically 51.2V in LiFePO4 cells), electrical current is significantly reduced compared to 12V or 24V equivalents delivering the same output power. This reduction in current results in lower thermal generation, less transmission resistance, and the ability to use thinner, lighter, and more cost-effective copper wiring.
A capacity rating of 100Ah at 48V yields exactly 4.8kWh of nominal energy storage. This standardized capacity block provides engineers with modular scaling capabilities. Whether deployed as a standalone unit for light material handling equipment, or arrayed in parallel configuration to build massive megawatt-hour (MWh) energy storage systems, the 48V 100Ah form factor simplifies thermal management, battery state estimation (SOC/SOH), and logistical handling. Standardized dimensional layouts allow these packs to fit perfectly within standard 19-inch server racks for telecom backup power.
Founded in 2009, Hangzhou LIAO Technology Co., Ltd. is a professional and leading manufacturer specialized in high-safety LiFePO4 (Lithium Iron Phosphate) batteries. With our headquarter and advanced manufacturing facilities located in Hangzhou, China, our engineered products have been successfully exported to more than 20 countries and territories worldwide, establishing a brand synonymous with quality, durability, and customized excellence.
Over the years, we have built a strict, comprehensive, and highly efficient Quality Control (QC) infrastructure. All our processes are certified and run strictly under the quality management system of ISO 9001. Furthermore, we maintain complete compliance with environmental management system ISO 14001 and occupational health and safety management system ISO 18001 (ISO 45001), ensuring that our energy solutions are built safely, responsibly, and sustainably.
Leveraging advanced processing technologies, proximity to raw material precursors, and automated production pipelines to deliver premium OEM modules.
From raw slurry mixing, precision rolling, and die cutting to automated laser welding, Hangzhou LIAO integrates high-end machinery to maintain nanometer-level tolerances.
Based in Hangzhou, China, we source battery precursors and structural elements directly from Tier-1 mines and refinery networks, insulating partners from global price shocks.
Every single prismatic cell is subjected to 3 full charge/discharge cycles for exact capacity sorting, resistance matching, and static voltage grading prior to module pack assembly.
Transparent insights into our facility layout, cleanroom spaces, and safety-assurance workstations.
Hangzhou LIAO Technology relies on continuous research and development to set safety benchmarks for lithium chemistry.
Our proprietary LiFePO4 cells will not catch fire, burn, or explode during severe mechanical acupuncture or crush testing. Perfect thermal stability prevents thermal runaway.
Engineered for extreme operating environments. The battery pack operates normally and discharges within a broad temperature window of -40℃ to 85℃.
A single LiFePO4 cell retains >80% of its initial capacity after 2800+ cycles under continuous 1C charge/discharge at 100% Depth of Discharge (DOD).
Our flagship LAXpower-1230 modules were officially awarded testing champion in rigorous performance evaluations conducted in Europe, confirming our technical superiority.
For over 15 years, LIAO has assisted over 500 business customers worldwide in developing customized battery designs for specialized industrial and commercial fields. Our integrated engineering department consists of highly trained electrical and mechanical engineers who design complex Battery Management Systems (BMS), structural enclosures (IP65/IP67 ratings), and custom communication protocols (CANbus, RS485, Modbus).
R&D Integration: Our design teams handle standard voltage scaling, thermal runaway profiling, active balancing networks, and sheet metal casing designs, delivering turnkey, high-performance battery packs that bypass costly, time-consuming integration trials.
Partnering with LIAO enables businesses to dramatically reduce their Time-to-Market (TTM), save capital expenditures (CAPEX) on battery testing facilities, and scale operations seamlessly.
Providing complete regulatory pathways, documentation sets, and local logistics coordination across primary target markets.
Entering international commercial markets requires batteries to comply with complex certification pathways. LIAO ensures that every product batch is backed by safety and logistical certifications, enabling smooth shipping, warehousing, and operational approvals.

Our standard 48V 100Ah LiFePO4 battery pack designed for telecom server racks has dimensions conforming to the standard 19-inch cabinet configurations (typically 4U or 5U high, approximately 442mm x 480mm x 177mm). The total weight is roughly 43kg to 45kg, which is less than half the weight of an equivalent lead-acid battery bank (which would require four 12V 100Ah blocks wired in series, weighing close to 120kg).
Yes. LIAO 48V 100Ah battery packs are built with customizable communication protocols (CANbus, RS485, RS232, and Modbus). The integrated smart BMS is pre-configured to communicate directly with major inverter brands globally (such as Growatt, Victron, Deye, SMA, and GoodWe). This ensures accurate State of Charge (SOC) tracking and automated charging profiles.
LiFePO4 (Lithium Iron Phosphate) offers major advantages for commercial and stationary applications:
Our smart Battery Management System (BMS) offers complete system protection: Over-charge voltage cutout, over-discharge voltage cutout, over-current cutoff, short-circuit protection, cell-balancing circuitry, and temperature sensors that disable charging at freezing temperatures (unless equipped with internal heaters) or shut down the battery in over-temperature situations.
For custom configurations, our MOQ depends on the modifications requested. Standard designs with customized labeling or logo prints generally have an MOQ of 10 to 20 units. Fully customized cases, specific custom BMS protocols, or complex mechanical redesigns may require a higher initial order quantity to offset design, tooling, and certification costs.
