High-quality custom rechargeable battery cells and engineering components designed to power global technology frameworks.
The 12V 30Ah LiFePO4 battery represents a critical sweet spot in modern electrochemical engineering, balancing high energy density, ease of modular integration, and structural stability. Utilizing Lithium Iron Phosphate (LiFePO4) chemistry, this system operates on a nominal voltage of 12.8V, achieved through a 4S (four cells connected in series) configuration. The robust crystal structure of iron phosphate does not breakdown during continuous cycling, mitigating the risk of thermal runaway and oxygen release that affects traditional lithium cobalt oxide (LCO) or nickel manganese cobalt (NMC) formulations.
For engineering procurement teams looking to phase out legacy Sealed Lead Acid (SLA) or Absorbent Glass Mat (AGM) setups, transitioning to a 12.8V 30Ah LFP chemistry offers major upgrades: an equivalent usable capacity with up to 70% weight reduction, zero maintenance overhead, and a highly linear discharge curve that ensures stable voltage delivery throughout 90% of the state-of-charge (SoC) profile.
Information Gain Insight: While a typical lead-acid battery provides only 50% usable depth of discharge (DoD) before voltage drop damages the cells, Hangzhou LIAO Technology's LiFePO4 packs can consistently access 100% of their rated 30Ah capacity at 1C discharge rates without shortening the cell lifespan.

Founded in 2009, Hangzhou LIAO Technology Co., Ltd. has established itself as an industry pioneer, focusing on the research, development, and high-volume production of top-tier lithium iron phosphate solutions. Supported by a rigorous quality control framework certified under ISO 9001:2015, an environmental compliance model conforming to ISO 14001, and occupational health protocols under ISO 18001, we run clean, modern, and highly precise production lines in China.
Our batteries have been deployed in more than 20 countries worldwide, with a major B2B footprint across Germany, France, the Netherlands, the UK, the USA, Australia, Japan, and South Africa. Our manufacturing team matches robust core technologies with a complete R&D system, enabling customized solutions that address demanding industrial requirements.
Our LiFePO4 cells are puncture-tested to ensure they will not burn, smoke, or explode under extreme mechanical acupuncture. Structural integrity remains stable even under high physical compression.
Designed to operate and discharge reliably across an ultra-wide temperature envelope ranging from -40 °C up to 85 °C, making them suitable for sub-zero marine, polar, or desert operations.
Delivers more than 2,800 full cycles under 1C charge and discharge conditions at 100% Depth of Discharge. This equates to over 8-10 years of daily operation with negligible capacity degradation.
Our high-capacity LAXpower-1230 design was officially awarded testing champion honors during independent B2B testing benchmarks in Europe, proving its performance and reliability.
China leads the world in lithium-ion battery manufacturing, housing more than 75% of global cathode production, cell refining capabilities, and automated packing infrastructures. Hangzhou LIAO Technology leverages this localized ecosystem to provide premium materials, shorter production timelines, and cost advantages to our global B2B clients.
Our facility integrates advanced battery assembly techniques, featuring:
A 12V 30Ah configuration offers a highly versatile form factor for deep-cycling applications. In B2B contexts, our clients integrate these packs directly into diverse modular and system-level setups:
Modern golf courses demand quiet, emission-free transport. Transitioning to LiFePO4 batteries reduces weight, increases speed, prevents acid-leak corrosion, and extends runtime across varied terrains.
Our LiFePO4 packs allow caravan movers to navigate steep or uneven pathways. The high continuous discharge current ensures reliable torque, reducing downtime and maintenance.
Automated Guided Vehicles (AGVs) rely on high-rate charge acceptance and long life. Our custom battery packs support fast-charging cycles, helping logistics centers keep warehouse vehicles running 24/7.
Marine environments require salt-spray resistance and safety. Our sealed ABS casing packs deliver auxiliary power for bilge pumps, fish finders, and navigation systems without environmental hazard.
Hangzhou LIAO Technology specializes in tailoring lithium solutions to specific client applications. With over 13 years of technical experience in custom battery design, we match custom cells with optimized system integrations. Our OEM/ODM pipeline includes:
We maintain a complete documentation portfolio, enabling fast customs clearance and regulatory approval for our clients. Below is a sample of our international certification compliance, including UN38.3, CE, and RoHS reports:
The global transition toward green energy is accelerating, driven by strict carbon emissions targets and the expansion of industrial automation. Within the low-voltage storage and mobile auxiliary power markets, the 12V LiFePO4 battery is rapidly becoming the default choice. Key trends shaping the future of this chemistry include:
High-durability cells, off-grid inverters, and high-discharge scooter battery packs for specialized commercial markets.
