Product with a Rechargeable Lithium Battery on Amazon – What Do I Need to Know?

I’m planning to sell a product on Amazon US that includes a rechargeable lithium battery, and I want to make sure I meet all the necessary requirements. From what I’ve heard, there might be specific documentation, testing, and certifications needed to comply with Amazon’s policies and U.S. regulations.

Can anyone share insights or personal experiences with:

Testing or certifications (e.g., UN 38.3)? Required documentation for listing approval on Amazon? Shipping restrictions or special packaging requirements? Any unexpected hurdles you’ve encountered when selling battery-powered products?

I’d really appreciate any advice, resources, or tips to make sure I get this right. Thanks in advance!
