[chbot] LiPo batteries

[Kay edgecumbe]

from an expolsion due to over chageing this was the result

the carbon was distributed widespread and the alloy foil and copper foil as well  

the explosion did not wake me up so probably a fizz whoosh.

 

other chemistries are a lot more explosive

the over charge probably produced a gass that eventually overcome the tiny vent hole and blew the contents all over the workshop
 

lesson learnt  use a BMS
