Explore our premium grade LiFePO4 cells, modules, and intelligent battery packs engineered to meet rigorous international standards for safety, endurance, and operational efficiency.
The global transition from legacy lead-acid batteries to lithium iron phosphate (LiFePO4) represents a technological paradigm shift. Driven by net-zero emission mandates and the urgent need to optimize operational expenditures, commercial enterprise and industrial fleets are redesigning their power architecture around lithium's superior metrics.
Unlike lead-acid systems, which suffer from limited cycle life, efficiency degradation at high C-rates, and mandatory maintenance schedules, modern LiFePO4 Chemistry offers virtually flat voltage discharge curves, near-zero round-trip efficiency loss, and up to ten times the operating lifespan.

Our commitment to cutting-edge research is validated by a strong portfolio of national patents and international test accolades. We don’t just manufacture batteries; we set performance benchmarks.
LIAO Technology develops lithium iron phosphate batteries using cell structures engineered to prevent thermal runaway, sustain ultra-wide thermal ranges, and ensure consistent output power.
Our LiFePO4 cells will not catch fire or explode even under high-velocity acupuncture / nail penetration tests. Structurally stable olivine crystal lattices retain oxygen atoms securely, preventing violent combustion.
Operates reliably from -40°C up to 85°C. Ideal for extreme climates, military applications, and demanding industrial environments where other chemistries undergo rapid capacity loss or BMS shut-down.
Achieves 2800+ full cycles at 1C discharge rate and 100% Depth of Discharge (DOD). At typical operational regimes of 80% DOD, the lifespan extends beyond 5000 cycles with SOH remaining above 80%.
Our LAXpower-1230 battery module was awarded the testing champion in independent European energy comparison panels, confirming outstanding energy efficiency, thermal stability, and assembly quality.
LIAO Technology partners with global OEMs to design, balance, and configure battery systems targeted at specific industry operating requirements, duty cycles, and environmental factors.
The new generation of LiFePO4 golf cart batteries from LIAO is optimized to handle high instantaneous draw during steep climbs and prolonged usage across various golf terrains. Our packs feature integrated smart BMS systems that communicate directly with the cart controllers to optimize energy consumption, extend range by up to 40% compared to equivalent lead-acid weights, and eliminate off-season self-discharge decay.
Operating a caravan mover demands heavy starting currents under load. LIAO LiFePO4 batteries deliver high discharge rates cleanly, allowing movers to operate quietly without voltage drops. The light footprint (up to 70% weight reduction compared to lead batteries) improves fuel efficiency for towing vehicles, while our sealed ABS configurations resist vibration and mechanical shock from unpaved roads.
In materials handling, uptime is revenue. Our forklift and Automated Guided Vehicle (AGV) battery modules support rapid opportunity charging (e.g., charging during 15-minute breaks) without thermal stress or cycle degradation. LIAO batteries enable industrial fleets to operate 24/7 without battery swaps, saving floor space, overhead cranes, and labor overheads.
Electric boats and utility marine craft operate in environments that require total system isolation and marine-grade sealing. Our custom e-boat marine systems prevent moisture intrusion and salt corrosion. Delivering flat voltage curves ensures consistent propulsion motor RPM even at low states of charge (SOC), backed by zero emission profile to preserve marine ecosystems.
How Hangzhou LIAO Technology leverages regional industrial clusters to guarantee material access, lower production costs, and maintain quality assurance.
Hangzhou, located in China’s premier manufacturing corridor (Zhejiang province), gives LIAO Technology access to local supply chains for lithium iron phosphate raw materials, high-purity copper current collectors, advanced separator films, and customized BMS microcontrollers. This dense ecosystem reduces logistics lead times and shields our manufacturing operations from global material price volatility.
By using local raw materials, we control purity levels directly from precursor stage to cathode manufacturing. This directly limits internal resistance (IR) variations across cells. Our proximity to the major shipping ports of Ningbo and Shanghai further guarantees fast customs clearance and secure shipping routes for international orders.
Furthermore, LIAO's factory layout optimizes workflow routing: electrode rolling, die-cutting, automated capacity sorting, stacking, and laser welding are organized in a continuous, climate-controlled clean room environment. Constant temperature and humidity levels prevent lithium salt degradation, maintaining consistency across batch production runs and lowering manufacturing defect rates below 50 PPM.
A forward-looking view into our current R&D, chemical innovations, and next-generation battery architectures.
LIAO is currently testing and qualifying Lithium Manganese Iron Phosphate (LMFP) cells. By blending manganese into the olivine crystal structure, we increase nominal cell voltage from 3.2V to 3.7V, unlocking a 15-20% increase in volumetric energy density while preserving the safety profile of traditional LFP chemistry.
Future iterations of our heavy-duty industrial and AGV battery packs will feature integrated 4G/5G telematics modules. This enables real-time, cloud-based monitoring of individual cell state of charge (SOC), state of health (SOH), temperature profiles, and predictive thermal runaway algorithms, facilitating proactive fleet maintenance.
To prepare for the next decade of energy storage, our engineering team is collaborating with research institutions to develop semi-solid state LiFePO4 cells. These cells aim to completely eliminate liquid electrolyte leakage risk, widen temperature tolerance from -50°C to 100°C, and double the volumetric energy density.
LIAO Technology complies with strict safety and environmental standards to ensure smooth product transport and operations globally.
Navigating the complex regulatory landscape of international lithium battery imports requires strict compliance. LIAO products are certified under a comprehensive suite of standards, including UN38.3 (Safe Transport of Lithium Batteries), CE (European Conformity), and RoHS (Restriction of Hazardous Substances). This ensures that our OEM battery packs pass customs without delay and meet the safety requirements of local jurisdictions.
For custom industrial and telecom projects, we manufacture battery packs in accordance with IEC 62619 (Safety requirements for secondary lithium cells and batteries in industrial applications) and UL 1973 (Batteries for Use in Stationary, Vehicle Auxiliary Power and Light Electric Rail Applications). This helps minimize liabilities and ensures compatibility with local insurance policies for our clients.
We work with accredited dangerous goods transport partners to manage international logistics. Whether shipping via Sea (FCL/LCL) or Air Cargo, every shipment includes full documentation, including Material Safety Data Sheets (MSDS), UN38.3 test summaries, and certified packaging designs that withstand drops and crushing forces. This ensures your delivery arrives safely and in compliance with international transport regulations.
Get answers to common technical, chemical, and design questions when planning custom LiFePO4 battery packs.
We primarily utilize Grade-A, brand-new prismatic cells (e.g., 3.2V 50Ah, 100Ah, 200Ah) sourced from verified tier-1 raw materials clusters, as well as our own manufactured cells. For space-constrained designs, we can also deploy high-rate cylindrical cells. Every cell undergoes strict internal resistance (IR) matching and capacity grading before being assembled into modules.
Our custom BMS modules feature both passive balancing (standard, dispersing energy via resistors) and active balancing (optional, shifting charge from higher cells to lower ones). We support standard industrial protocols including CANbus, RS485, Modbus, and SMBus, allowing easy integration with motor controllers, vehicle ECUs, and inverters.
Standard energy storage and golf cart packs are designed for 1C continuous discharge and 3C peak discharge (for 5–10 seconds). For heavy-duty industrial vehicles and high-torque caravan movers, we can build custom high-rate configurations that sustain up to 3C-5C continuous discharge, backed by custom thermal management systems.
Standard LiFePO4 batteries exhibit reduced charge acceptance and capacity in sub-zero environments. For cold-climate applications, we integrate internal heating films managed by the BMS. When a charging current is detected, the BMS routes power to the heating pads to warm the cells above 0°C before charging begins, preserving cell chemistry and cycle life.
We manufacture battery housings ranging from standard IP54 (dust and splash protected) up to IP67 (completely dust-proof and waterproof under temporary immersion). Our marine batteries and outdoor telecom batteries use custom silicone gaskets, compression seals, and marine-grade stainless steel hardware.
For custom casing and BMS development, prototype samples are typically delivered in 4 to 6 weeks. This includes initial CAD designs, thermal simulation, component sourcing, BMS programming, assembly, and 72-hour test validation cycles under load.
Yes. For high-rate or dense solar ESS installations, we design systems with active forced air cooling or liquid cooling channels. This ensures the maximum cell temperature differential remains under 3°C, extending pack lifetime and safety.
Our packs exhibit a self-discharge rate of less than 2% per month when stored at 25°C, compared to 15-20% for typical lead-acid batteries. We recommend a refresh charge every 6 months during long-term storage.
Our BMS employs double hardware overcurrent protection and software thresholds. It monitors current draw in real-time. If currents exceed nominal thresholds, the BMS triggers a timed alert, and if it exceeds the maximum safe limit, it disconnects the MOSFETs or triggers the safety contactor in under 5 milliseconds to protect the cells.
Yes, we maintain global product liability insurance cover for all exported products. Additionally, we provide comprehensive technical support and design documentation to ensure end-system integrations comply with local safety regulations.
