What is UN38.3 and why does the ETENWOLF S0 battery need it?

UN38.3 is the United Nations standard that defines safety tests lithium batteries must pass before they can be transported by air, sea, or road. The ETENWOLF S0 contains a 7.4V / 8.88Wh lithium-ion battery pack subject to these regulations. MSDS reference WTH25D09245621B001 confirms compliance, enabling international shipment.

Is the lithium-ion battery in the ETENWOLF S0 dangerous under normal use?

No. The MSDS states the battery is not classified as dangerous under normal use. The sealed case is engineered to withstand normal operating conditions. Hazards only arise in cases of rupture, fire exposure, disassembly, or other improper handling.

What should I do if the battery in my ETENWOLF S0 is damaged or leaking?

Avoid skin and eye contact with leaking electrolyte. Move to a well-ventilated area. Flush affected skin or eyes with clean water for at least 15 minutes and seek medical attention. Do not recharge or use a damaged battery. Dispose in accordance with local lithium battery waste regulations. Emergency contact: 0762-3429081.

Key Details

The MSDS covers seven sections addressing all critical safety dimensions of the battery pack. The key findings from each section are summarised below.

Section 1 – Chemical Product and Company Identification

The product is a sealed lithium-ion battery pack, model 2S1P-1200, rated at 7.4 V / 1200 mAh / 8.88 Wh, weighing approximately 62.7 g. It is manufactured by Guangdong Bestek Technology Co., LTD in Heyuan City, Guangdong, China.

Section 2 – Hazards Identification

Under normal operating conditions the battery presents no danger. Hazards arise only in the event of rupture or improper handling. Hazard summaries by exposure route are as follows:

Classification: Not classified as dangerous under normal use. All hazards listed apply specifically to a ruptured or compromised battery.
Appearance: Solid object, no odour, no colour.
Skin Contact: Electrolyte leakage may cause skin irritation and soreness.
Eye Contact: Electrolyte vapour may cause eye inflammation and irritation.
Inhalation: Vapours or mists from a ruptured battery may cause respiratory irritation; inhalation from a sealed battery is not an expected exposure route.
Ingestion: Swallowing is not anticipated due to battery size; ingestion of electrolyte can cause tissue damage to the throat.
Health Hazards: Chemical materials are stored in a sealed metal or metal-laminated plastic case designed to withstand temperatures and pressures during normal use. Exposure to fire, strong mechanical shock, or decomposition may cause electrolyte leakage and emission of acrid gas.
Environmental Hazards: Electrolyte leakage or battery contact with water may present environmental hazards; dispose of in accordance with local regulations.

Transport Classification

Lithium-ion batteries are regulated for transport under UN38.3 (Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria). This MSDS confirms the battery pack meets the required safety criteria for air, sea, and ground transport when packaged in accordance with the applicable packing instructions.

Standards & Compliance

The battery pack for the ETENWOLF S0 has been evaluated against the following international regulations and standards:

Standard / Regulation	Scope
UN38.3	Transport testing requirements for lithium batteries (vibration, shock, external short circuit, impact, overcharge, forced discharge, thermal abuse, altitude simulation)
IATA Dangerous Goods Regulations	Air transport classification and packaging requirements for lithium-ion batteries
IMDG Code	Sea transport requirements for dangerous goods including lithium batteries
ADR / IMDG / ICAO	International road, sea, and air transport safety frameworks

The MSDS was compiled by Jason Zhen (Project Engineer) and approved by Deval Qin (Designated Reviewer) at Waltek Testing Group Co., Ltd., confirming all data was reviewed by qualified personnel prior to issue.

Validity & Certification Body

The MSDS was issued on 2025-09-26 and is valid for the product as long as the battery model and chemistry remain unchanged. Any alteration to battery cell chemistry, configuration, capacity, or voltage would require a new MSDS to be issued.
