-[* black] Battery caddy
-[* black] Battery cell
-[* black] Cells and circuit board, maybe charging control circuit?
+[* black] We've heard rumors that the Shield has a crazy battery life. We find three Sanyo battery cells that are responsible for the extended action.
+[* black] The case on the three-cell 3.7V, 7350mAh, rechargeable lithium ion battery is labeled 131907887.
+ [* black] These numbers mean plenty of play time.
+[* black] There is a small circuit board connecting the three cells of the battery. Our best guess? A charging control circuit.
