    Lithium Batteries Shipping Rules Discussions

    Yes, resolved. Now we ship batteries with EMS. UPS really sucks. There must be a guy or a team in KY who don't know anything about Lithium batteries and don't want to know, although we did provide all information. They held many packages to east coast and we had to full refund to those...

    ping is not a brand

    Cammy, It seems your "sorry" was not said to me, but to all the others who could be your potential customers. However, I think you'd better apologize to me first. Please don't explain what "ping" means. eBay.com is a US website and we are both Chinese. Even if "ping" means "cheap", why didn't...
