For manufacturers, distributors, and consumers using EVE LF100MA 100Ah 3.2V LiFePO4 battery cells, understanding the necessary certification requirements is crucial. These certifications are not only about legal compliance but also serve as important guarantees of battery safety and quality.

UN38.3 Certification: A Mandatory Requirement for Transportation
UN38.3 is a mandatory certification for the transportation of lithium-ion batteries, applicable to all modes of transport (air, sea, road, and rail).
Why is UN38.3 Certification So Important?
Lithium-ion batteries are classified as Class 9 hazardous materials. This is stipulated by the United Nations Regulations Model in the “Manual of Tests and Criteria,” Section 38.3, because batteries may pose a fire risk.
Lithium metal is highly reactive and unstable. While it provides high energy density, it can undergo “thermal runaway,” leading to leakage, rupture, explosion, or fire.
The Eight Test Items for UN38.3 Certification
-
T1 – Altitude Simulation: Simulates low-pressure conditions (primary and secondary cells/batteries).
-
T2 – Thermal Test: Integrity check under rapid temperature changes (primary and secondary cells/batteries).
-
T3 – Vibration: Simulates vibration during transportation (primary and secondary cells/batteries).
-
T4 – Shock: Simulates impact during transportation (primary and secondary cells/batteries).
-
T5 – External Short Circuit: Simulates an external short circuit (primary and secondary cells/batteries).
-
T6 – Impact/Crush: Simulates impact and crushing on the battery casing (primary and secondary cells).
-
T7 – Overcharge: Simulates overcharging of rechargeable batteries (secondary batteries).
-
T8 – Forced Discharge: Simulates forced discharge of batteries (primary and secondary batteries).
To pass these tests, the battery or battery pack must not leak, vent, disassemble, rupture, or ignite. Furthermore, the open-circuit voltage of the sample must be 90% of the voltage measured before testing.
UN38.3 Classification and Packaging Requirements
Based on battery type and mode of transport, there are four different classifications:
-
UN 3480: Lithium-ion batteries shipped separately (including cells shipped individually, battery packs shipped separately, etc.)
-
UN 3481: Lithium-ion batteries packed with or installed in equipment
-
UN 3090: Lithium metal batteries shipped separately
-
UN 3091: Lithium metal batteries packed with or installed in equipment
For lithium-ion batteries shipped separately, the state of charge must be set at 30% or less (applicable to air cargo), and packaging that meets the regulations must be used.
CE Marking: The Key to EU Market Access
Overview of the New EU Battery Regulation
The EU passed a new battery regulation (Regulation 2023/1542) in July 2023, which came into effect on February 18, 2024. The new regulation aims to harmonize legislation on battery sustainability and safety.
According to the new regulation, all batteries sold on the EU market must bear the CE mark, whether they are used alone or in products.
Battery Classification and New Requirements
The new regulation categorizes batteries into five types:
-
Portable batteries
-
Light Means of Transport (LMT) batteries
-
Starting, Lighting, and Ignition (SLI) batteries
-
Industrial batteries
-
Electric Vehicle (EV) batteries
The CE conformity assessment and CE marking requirements became applicable from August 18, 2024.
Battery Passport and Due Diligence Requirements
The EU Battery Regulation introduces several important new requirements:
-
Battery Passport: For each industrial battery (with a capacity exceeding 2 kWh), EV battery, and LMT battery (such as e-bike batteries), a separate electronic battery passport is required. The battery passport obligation will take effect from February 18, 2027.
-
Supply Chain Due Diligence Obligations: Apply to batteries placed on the EU market or put into service, involving raw materials such as cobalt, natural graphite, lithium, or nickel. Supply chain due diligence obligations will take effect from August 18, 2027.
-
Replaceability Requirements: Portable batteries should be designed for easy removal and replacement by end-users at any point during the product’s lifetime. These requirements will apply from February 18, 2027.
Practical Application Guide
Specific Certifications for LF100MA Battery Cells
According to supplier information, EVE LF100MA battery cells typically come with certifications such as UL, MSDS, UN38.3, CE. However, as a user or distributor, you must still ensure the validity and authenticity of these certifications, especially during large-scale shipments.
Steps to Obtain Certification
-
Select an accredited testing laboratory: Such as Intertek, TÜV SÜD, or Eurofins.
-
Prepare samples: Typically, about 16 battery packs are required for testing.
-
Conduct testing: The testing process usually takes 4-6 weeks.
-
Obtain test report and summary: The test report is about 10 pages long and contains detailed technical information.
-
Prepare shipping documents: Including the test summary and packaging that meets transportation requirements.
Important Considerations
-
If the battery or cell is redesigned after certification, lithium-based batteries or cells must be retested to obtain new certification.
-
Certifications cannot be transferred between suppliers. Even if the battery design remains unchanged, a new supplier needs to obtain battery certification.
-
For portable batteries and industrial batteries with a capacity of less than 2 kWh, the CE conformity assessment is a self-certification process. For all other batteries, involvement from a notified body is required.
Summary
When transporting and selling LF100MA battery cells globally, UN38.3 certification is a mandatory requirement, while the CE mark is a necessary condition for accessing the EU market. With the implementation of the new EU Battery Regulation, battery producers and distributors need to pay attention to upcoming new requirements, particularly the battery passport and supply chain due diligence obligations.
Adhering to these certification requirements not only ensures compliance but also guarantees battery safety and quality, ultimately protecting the interests of all parties involved.
