I don't see enough talk about Lithium POLYMER (LiPo) batteries...
Those things are exceedingly dangerous and volatile, by comparison to Lithium Ion..
Nope. LiPo batteries in the market are simply Lithium-Ion batteries with a soft (polymer) casing. They may have a
slightly higher energy densities vs. more common types of Lithium-Ion -- but are otherwise identical from a safety perspective.
They are not inherently any more dangerous. They have a bad reputation because people buy cheap high capacity LiPo batteries from unknown manufacturers in China then wonder why they explode. But a well manufactured LiPo isn't any more dangerous than other well manufactured Lithium Ion batteries.
