Look at lines 9 & 10 on attached pic
LION is usually metal cased like the batt's in a laptop. Looks like a large
AA battery, round and long.
LIPO are in poly sacks like shown in pics for cam. Flat and wide.
My other cameras, cell phone, etc. also use Li-Ion cells but in flat hard shell cases just slightly larger than the #11 Lipo cells. Not all are cylinders.
