Could someone please explain the customs problem with lithium batteries from Gearbest. I don't understand why they take orders they know they can't ship. I would have ordered from an American company if I knew it was a problem.(cheaper price from US supplier) At the suggestion of a forum member ,I bought a Convoy S2+, battery,and charger from Gearbest with links. The light and charger came no problem.The battery may take forever.
