Ling, excellent points!! With the switch to Lipos in every series, such as our TCS, this is all information that will be very useful when teching batteries. This article was pointed out to me today, after which, I went to look up how quickly the Lipos can become a danger. Sure enough, youtube is full of video tests showing how mistreating packs can lead to serious problems.

the you tube stuff is interesting on the overcharge and results of that issue.

Precautions
Lithium metal, due to its alkaline tarnish, is corrosive and requires special handling to avoid skin contact. Breathing lithium dust or lithium compounds (which are often alkaline) can irritate the nose and throat; higher exposure to lithium can cause a build-up of fluid in the lungs, leading to pulmonary edema. The metal itself is usually a handling hazard because of the caustic hydroxide produced when it is in contact with moisture causing an explosion. Lithium should be stored in a non-reactive compound such as naphtha or a hydrocarbon.[citations needed]
