Mine is in shipped status, and I made sure the page was telling us LIPO. One previous report in this thread showed the batter marked LIPO and the packaging as just LI.
Can't complain til I see the product, but for the moment it sounds like you didn't get what you paid for.
Here's the link to the one I bit on:

Back of the battery is the only place polymer is mentioned. Hmm.
