I need to send light with a 10440 in it Via usps can it be done priority? Is there a fee for having it? Do they make you show them? Do I have to unwrap the package? I've read something must be installed so it doesn't come on? What else is needed?
Do you tell them?If it's installed you're good to go. I've shipped many lithiums through USPS without an issue.
Do you tell them?
