batteries - Water on Li-Ion battery fire: good idea, bad idea, or neutral?


I always thought (like this guy) that putting out a Li-Ion battery fire with water was a bad idea because of the reaction between water and lithium.


But now I read from one source:



Lithium-ion batteries contain little lithium metal and in case of a fire they can be dowsed with water. Only lithium-metal batteries require a Class D fire extinguisher.



Is this accurate? Can I really use water on Li-Ion battery fires?


And if so, is this safe for batteries of any capacity, or is it dangerous beyond some mAh?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
