What is the UN38.3 standard and why does the HB2 battery need it?

UN38.3 is the United Nations standard that mandates a series of safety tests for lithium batteries before they can be transported by air, sea, or land. The ETENWOLF HB2 contains a 7.4V 2000mAh lithium-ion battery pack (model 2S1P-2000), which falls under this regulation. The MSDS reference WTH25D07201659B001 supports the UN38.3 compliance documentation package for this product.

Is the HB2 battery pack dangerous during normal use?

No. According to the MSDS (reference WTH25D07201659B001), the battery is classified as not dangerous under normal use. The chemical materials are sealed in a metal or metal-laminated plastic case designed to withstand standard operating temperatures and pressures. Hazards arise only in the event of physical rupture, exposure to fire, or improper use such as short-circuiting or crushing.

What chemicals are inside the HB2 lithium-ion battery pack?

The 2S1P-2000 battery pack contains Lithium Cobalt Oxide (LiCoO2, 32.7%), Nickel (22%), Carbon (15%), Copper (10%), Polypropylene (5.4%), Aluminum (4.2%), Ethylene Carbonate (4.0%), Dimethyl Carbonate (3.7%), Lithium Hexafluorophosphate (2.5%), and PVDF (0.5%). Full CAS numbers for each component are provided in the product MSDS.

What should I do if the HB2 battery leaks or ruptures?

If the battery ruptures, avoid all contact with the electrolyte. For skin contact, flush with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of water and seek medical attention. Move to fresh air if vapors are inhaled. Wear rubber gloves, safety goggles, and protective clothing when handling a leaking battery. Do not dispose of it in fire. Contact the manufacturer emergency line at 0762-3429081 if necessary.
