The history of Lithium Ion batteries is not very flattering and their adverse effects in aircraft not that reassuring despite some positive characteristics.
If I might point to the volatility of these batteries whilst adding I acknowledge they were NOT connected to an electrical system at the time, they did bring down a B747-400 in Dubai in recent times.
Were lessons NOT learnt?
Is their lightness of weight, their ability to quickly recharge despite the residual heat they omit with such potential for disaster truly worth it?
Apparently.
This is what we get when manufacturers are pressurized by an industry that is so driven by the bottom line.
That's not news but that too is reality.
