RE: Electric Fliers; Check this:
The main difference between Lithium Ion and Lithium Polymer is the durability of the cells. Lithium Ion being in a metal can are much less susceptible to physical damage which could cause shorting. Otherwise the same hazards exist. The cells in the laptop battery fiasco I understand were cylindrical Lithium Ion cells, not the Lithium Polymer. If you tear down a laptop battery you will find cells designated 18450 or something on that order. The one I just looked at (Gateway - Solo 5300 14.4 V 3600 mAh) had Sony cells, in 2P4S configuration. Two cells connected in parallel and then 4 of these in series. There were taps to a fairly complex circuit board from each node of the of the battery. Testing these cells in 2 cell parallel pairs indicates the pack was pretty sick from capacity delivery standpoint. Now I'm going to move them outside and see if anything happens from a constant current charge of 6-8 amps.
