Discover our engineered lithium iron phosphate (LiFePO4) cell architectures and intelligent customized battery packs, designed for extreme durability, long cycle life, and thermal safety under demanding load characteristics.
The global battery market is experiencing a profound paradigm shift. The classic 12V 20Ah lead-acid block—historically the workhorse of uninterruptible power supplies (UPS), mobility scooters, electric golf caddies, and miniature solar storage grids—is rapidly being phased out. Today's commercial and industrial enterprises demand systems that offer a lower total cost of ownership (TCO), longer cycle lifetimes, and reduced system footprints.
A conventional lead-acid battery offers roughly 300 to 500 cycles at a limited 50% Depth of Discharge (DoD) and exhibits a sharp drop in voltage during high-rate discharge. By contrast, a 12V 20Ah LiFePO4 battery pack engineered with premium prismatic or cylindrical cells delivers over 2,800 full cycles at 100% DoD while sustaining a stable voltage plateau near 12.8V. This translates to an operational service life extension of more than five times, reducing system replacement overheads and maintenance costs to virtually zero.
Founded in 2009, Hangzhou LIAO Technology Co., Ltd. has established itself as a professional, leading manufacturer specializing in high-performance lithium iron phosphate (LiFePO4) battery systems. Over the course of 15 years, our engineering innovations have allowed us to design and scale energy solutions that serve clients in more than 20 countries, including highly demanding regions across Germany, France, the UK, the Netherlands, Spain, the US, Canada, Mexico, Brazil, Japan, Korea, India, and Australia.
We pride ourselves on an integrated Quality Control hierarchy. Operating strictly under the globally recognized ISO 9001 quality management framework, we preserve clean, safe manufacturing loops. Furthermore, LIAO is fully certified and compliant with the environmental protocols of ISO 14001 and the occupational health and safety standards of ISO 18001 / ISO 45001. This ensures that every battery pack shipped from our Hangzhou facility is built on a foundation of reliability, environmental protection, and workplace safety.
The 12V 20Ah battery pack sits in a sweet spot of energy density, mechanical flexibility, and transportability. Leveraging a built-in smart Battery Management System (BMS), it serves as a high-reliability block across residential, commercial, and light-industrial sectors:
Modern golf courses demand batteries that can navigate steep slopes, rough terrain, and extended play. Standard golf trolleys and buggies utilizing our LiFePO4 chemistry maintain consistent torque output without experiencing the typical late-stage voltage drop of lead-acid, keeping systems playing longer and recharging faster.
Maneuvering heavy caravans requires high burst current in a compact envelope. Our 12V 20Ah battery provides high cranking power to electric movers silently, with zero emissions or noxious gas venting, all while reducing structural deadweight on caravan chassis.
For short-distance logistics, heavy material transport, and Automated Guided Vehicles (AGVs) in warehouse corridors, these modules allow rapid fast-charging cycles, facilitating multi-shift schedules with minimal charging downtime.
Eco-friendly marine propulsion demands sealed, shock-resistant battery enclosures. The maintenance-free LFP chemistry keeps auxiliary systems and small electric trolling motors running safely without threat of acid spills or toxic emissions into aquatic environments.
True E-E-A-T (Expertise, Authoritativeness, and Trustworthiness) is demonstrated on the factory floor. Hangzhou LIAO Technology operates a vertical manufacturing plant where quality checks occur at every stage of the assembly process. Below is a tour of our specialized production blocks:
Our battery production line utilizes automated precision machines to eliminate human error. Key manufacturing phases include: Capacity Sorting: Every individual prismatic and cylindrical cell is graded to guarantee less than 1% divergence in internal resistance and capacitance. Baking & Die Cutting: Active materials are dried under strict vacuum and heat before being cut to microscopic tolerances. Laser Welding: Copper/Aluminum busbars are welded using high-energy fiber lasers to assure vibration-proof linkages suitable for dynamic electric vehicle installations.
The concentration of global lithium processing, cathode/anode production, separator manufacturing, and automated assembly in China allows us to offer an optimized supply chain that is highly resilient to macro-economic changes. While Western manufacturers face chronic cell component bottlenecks, our partnerships with major extraction and refining clusters guarantee uninterrupted production queues.
By sourcing raw lithium iron phosphate direct from verified processing plants, we insulate our global clients from volatile commodity prices. This gives LIAO the leverage to execute multi-year supply contracts at stable pricing brackets.
Our in-house electrical and mechanical engineers can take schematic blueprints from international customers and deliver functional, certified prototype packs within short turnaround windows. We customize form factors, wiring harnesses, communication protocols (CANbus, RS485, Bluetooth), and specialized metal casings.
From Incoming Quality Control (IQC) of active materials to Outgoing Quality Assurance (OQA) consisting of multi-day heat testing, vibration simulations, and high-current safety tests, we ensure that zero-defect shipments reach import ports.
LIAO Technology is constantly pushing the boundaries of chemical architecture and system intelligence. Our R&D team works in lockstep with national materials science institutes to build safer, denser, and smarter batteries. Below is our development roadmap leading into the next generation of energy storage:
Developing solid state polymer electrolytes to entirely eliminate liquid organic solvents, pushing thermal runaway thresholds up to over 150°C and improving volumetric energy density.
Integrating 5G/Narrowband IoT telemetry into custom battery packs. This allows remote tracking of state-of-health (SoH), cell temperatures, and preventative safety shutoffs over-the-air.
Establishing secondary life-cycle pathways. Partnering with domestic metallurgy recylers to reclaim over 95% of active copper, lithium, and iron from spent battery housings.
Entering international markets requires absolute compliance with local safety regulations. Over the years, Hangzhou LIAO Technology has invested heavily in certified test evaluations, ensuring that our cells and custom packs hold full documentation for logistics and installation:
Our solutions carry certifications including CE, UN38.3 (Logistics and transport safety), MSDS, and testing standard compliance reports that are necessary to clear customs and ensure legal installation in residential, municipal, and commercial systems worldwide.
Find answers to common questions about buying 12V 20Ah Lithium Iron Phosphate systems directly from China factories:
A 12V 20Ah LiFePO4 battery weighs approximately 1/3 of an equivalent lead-acid model (approx 2.5kg vs 6kg). It provides over 2,800 full charge/discharge cycles at 100% Depth of Discharge, whereas lead-acid typical outputs are limited to 300-500 cycles at 50% DoD. Furthermore, LFP maintains a flat voltage curve, ensuring constant power delivery throughout the entire discharge profile, and does not suffer from sulfation or structural degradation during prolonged storage in a semi-discharged state.
Every LIAO pack features an integrated Battery Management System (BMS) that monitors individual cell voltages, temperatures, and current flows in real-time. The BMS protects the pack against over-charge, over-discharge, over-current, and external short-circuits. Additionally, our LiFePO4 cells feature integrated safety vents that release localized gas build-ups under severe abuse without causing thermal runaway or combustion.
Yes. Depending on the integrated BMS design, our standard 12V 20Ah packs can be wired in series up to 4 units (to achieve a 48V output) or in parallel up to 10 units (to create a 12V 200Ah system). For custom series/parallel applications, we request that you contact our engineering team prior to placing orders so we can install a balanced BMS engineered for high-voltage or high-amperage systems.
For standard 12V 20Ah batteries, production lead times generally range between 15 and 25 days depending on batch quantities. For custom OEM/ODM projects requiring new metal casings, customized BMS configurations, or special connectors, the R&D design and prototyping stage takes 2-3 weeks, with mass production scheduled within 30-40 days after prototype approval.
All LIAO battery shipments are accompanied by a full transport dossier, including UN38.3 test summaries, MSDS profiles, safe packaging certificates, and declarations of dangerous goods. We work with specialized chemical freight forwarders to ensure clean customs clearance and regulatory compliance across major European, American, and Asian ports.
