Founded in 2009, Hangzhou LIAO Technology Co., Ltd. has pioneered the research, engineering, and mass production of premium Lithium Iron Phosphate (LiFePO4) systems. Our commitment to quality has driven the deployment of advanced power packs to over 20 countries globally.
We maintain an uncompromising quality assurance ecosystem under strict compliance with the international standard ISO 9001. Additionally, our production plants adhere to the environmental standard ISO 14001 and prioritize workforce health under ISO 18001 / ISO 45001 frameworks. Through systematic engineering controls, we deliver batteries that guarantee consistency, longevity, and extreme field safety.
The 48V 30Ah configuration offers an optimal balance of energy density, safety, and power capacity. Below are key applications where this standard delivers superior performance.
Our LiFePO4 technology provides reliable power for golf carts, sustaining high torque output over varying course elevations. Transitioning from lead-acid to 48V 30Ah packs significantly reduces vehicle weight, decreases turf compaction, and eliminates routine water maintenance.
Designed for caravan movers and off-grid auxiliary power, these packs deliver high instantaneous currents without voltage sag. This ensures reliable operation for tight maneuvers on soft ground, offering silent, emission-free energy storage.
Automated Guided Vehicles (AGVs) and warehouse logistics systems require reliable power. Our batteries support opportunity charging and fast-charge cycles, enabling 24/7 autonomous fleet operations with minimal downtime.
We optimize cell layouts through precision automated manufacturing. The core architecture uses Grade-A prismatic cells, which provide superior structural integrity and heat dissipation compared to pouch cells. A custom Smart BMS monitors voltage, temperature, and current parameters at the individual cell level.
| Electrical & Mechanical Parameters | Typical Specification (48V 30Ah LiFePO4) | Engineering Design Margin |
|---|---|---|
| Nominal Voltage | 51.2 V (16S Configuration) | Maintains stable plateau above 48V throughout 85% of discharge curve | Charging Cut-off Voltage | 58.4 V | Over-voltage margin managed by dual-tier BMS protection |
| Continuous Discharge Current | 30A / 50A Option | BMS designed with high thermal dissipation to prevent heat buildup |
| Internal Impedance | ≤ 20 mΩ | Low resistance design minimizes internal energy losses |
| Self-Discharge Rate | ≤ 2.5% per Month | Allows for long-term storage without excessive capacity loss |
| Cycle Life (100% DOD) | 2,800+ Cycles (Residual capacity >80%) | Extends beyond 4,000 cycles at 80% DOD or lower discharge rates |
Hangzhou LIAO Technology is committed to advancing active balancing circuitry, solid-electrolyte interfaces, and IoT-enabled BMS integration. By monitoring cellular status remotely, operators can calculate battery aging patterns, perform preemptive diagnostics, and maximize fleet ROI.
Our manufacturing facility in Hangzhou leverages automated production processes and strict quality control protocols to ensure reliable, high-performance battery assembly.
By leveraging regional supply chains in the Yangtze River Delta, we maintain stable access to raw materials like lithium carbonate and iron phosphate precursors. This direct access minimizes supply chain volatility and ensures reliable delivery times for global partners.
Our products are certified to meet international safety and transport requirements, including CE, UN38.3, and ISO compliance standards.
We provide technical consultations, schematic drawings, and evaluation samples for industrial partners worldwide.
