Premium OEM/ODM battery modules engineered for safety, long cycle life, and global distribution.
Hangzhou LIAO Technology Co., Ltd. (established in 2009) stands as an international tier-one specialist in the engineering and production of Lithium Iron Phosphate (LiFePO4) energy systems. Operating from state-of-the-art facilities, LIAO integrates robust material science with advanced power management engineering. Our products serve mission-critical applications across 20+ countries, complying with rigorous global engineering and logistics frameworks.
We have implemented comprehensive Quality Management systems under ISO 9001, Environmental protection standards under ISO 14001, and Occupational Safety measures under ISO 18001. This multi-layered framework ensures every cell leaving our production line delivers structural safety and reliable thermal performance.
Advanced chemical engineering and physical design attributes that define our industrial market advantages.
Our custom chemistry prevents thermal runaway. Cells undergo acupuncture and crush tests without ignition, explosion, or chemical leakage, assuring safety in marine and industrial environments.
Capable of sustained high-current discharge profiles spanning temperatures from -40°C up to +85°C. Reliable power delivery in extreme latitudes and temperature-controlled environments.
Our prismatic cells exceed 2,800 full charge-discharge cycles at 1C charge/discharge and 100% Depth of Discharge (DOD) before falling to 80% of original nominal capacity.
Marine environments require robust electrical architectures. As commercial fishing fleets, scientific research vessels, and recreational yachts transition to low-emission or fully electric propulsion, 24V LiFePO4 battery setups have emerged as the standard configuration. Compared to traditional 12V lead-acid configurations, a 24V lithium-ion layout offers substantial physical and electrical advantages:
How Hangzhou LIAO Technology delivers high-performance lithium energy solutions to specialized global markets.
Our next-generation LiFePO4 golf cart systems provide continuous voltage discharge profiles, allowing vehicles to traverse demanding terrains and elevation shifts without performance degradation.
Optimized energy packs that deliver clean, emissions-free power for caravan propulsion. These units require zero maintenance and significantly reduce onboard auxiliary battery weight.
High-discharge packs designed for automated guided vehicles (AGVs) and short-haul material transport. These systems support fast-charging, reducing idle times and operational overhead.
Zero-emission, low-noise marine energy packs. Designed with IP-rated enclosures and protective shock mountings to meet demanding maritime operating environments.
