CE Certified 20Ah LiFePO4 Battery Manufacturer & Factory

Direct OEM/ODM Industrial Energy Solutions from Hangzhou LIAO Technology Co., Ltd. – Engineered for Safety, Long Life Cycle, and Strict Global Compliance.

1. The Strategic Value of 20Ah LiFePO4 Batteries in Modern B2B Procurement

Within the commercial energy storage and electromobility sectors, the 20Ah LiFePO4 (Lithium Iron Phosphate) cell represents a critical engineering Sweet-Spot. It provides optimal capacity configuration flexibility, thermal stability, and mechanical manageability. Unlike high-capacity cells that demand extensive active cooling systems or lower-capacity cylindrical cells requiring thousands of connections, the 20Ah form factor allows for clean modular assembly in both series and parallel configurations (such as 12V 20Ah, 24V 20Ah, 36V 20Ah, and 48V 20Ah packs).

For systems engineers and procurement heads, sourcing from a manufacturer holding direct CE Certification is non-negotiable. This certification acts as a gateway for importing into the European Union and European Economic Area, providing verified compliance with critical safety, health, and environmental standards. It protects B2B buyers from legal liability, customs delays, and operational risks associated with uncertified battery components.

3. Technical Strengths & Safety Profiling

At Hangzhou LIAO Technology Co., Ltd., we engineer safety directly into the molecular structure of our batteries. The primary advantages of our cells include:

Best Safety Standards

LIAO cells will not burn or explode under aggressive physical penetration testing (acupuncture test). The structural integrity of our iron phosphate olivine crystal matrix prevents thermal runaway even under mechanical deformation.

Excellent Thermal Range

Our batteries are capable of reliable charge and discharge cycles within a wide environmental temperature range of -40 ℃ to 85 ℃. This ensures consistency in high-temperature desert climates and freezing Arctic conditions.

Long Cycle Life

A single LIAO cell delivers 2800+ cycles under 1C charge/discharge conditions at 100% Depth of Discharge (DOD). This performance translates to a decade of reliable operation in daily usage environments.

Our dedication to engineering quality has earned us recognition across Europe, where the LAXpower-1230 was officially awarded testing champion honors. This verification highlights our focus on energy density optimization and real-world efficiency.

4. Supply Chain Powerhouse: China Factory Infrastructure

Choosing Hangzhou LIAO Technology Co., Ltd. as your primary battery manufacturer in China unlocks massive supply chain benefits.

Frequently Asked Questions

Technical clarifications and procurement details from our engineering team.

What makes 20Ah LiFePO4 cells safer than alternative chemistry types?
The iron phosphate olivine crystal matrix has strong P-O chemical bonds, which keep the structure stable even under high temperatures. Under overcharge, short circuit, or acupuncture conditions, this chemistry resists oxygen release, preventing the thermal runaway common in cobalt-based lithium cells.
Can you handle custom configurations for OEM and ODM requests?
Yes. LIAO is an OEM/ODM provider. We build custom battery systems matching your required voltages (12V to 192V+), capacities, physical dimensions, and communication protocols (CANbus, RS485).
What quality standards do you follow during production?
We operate under a strict quality management system certified to ISO 9001. Environmental impacts are managed via ISO 14001, and our workplaces follow ISO 18001 guidelines. Our batteries carry CE certifications for export to European markets.
How does cell capacity sorting work at the LIAO facility?
Each cell undergoes testing in our automated capacity sorting system. We screen and group cells with matching capacity, internal resistance, and self-discharge rates. This ensures balanced cell wear and extends the lifetime of the assembled packs.
What is the normal operating temperature range for these packs?
Our batteries discharge reliably in a wide temperature range of -40 ℃ to 85 ℃. For cold-weather charging, we also design custom BMS solutions with integrated heating systems.
