Thanks Turin
Thank you for lots of useful information.
Seems the maximum charging rate is 45 A. Fair enough.
So the battery load in normal flight is only the emergency light wireless receivers.
As we know there is a diode unit in the output of the main battery. My question is is not possible to have the hot battery bus fed from a transformer rectifier unit in normal flight thus keeping the diode reverse biased?
Without any doubt batteries need to be fully charged during flight and recharged during flight if used. The question is with a self discharge rate of less than 15% per month does routine inflight charging need to take place?
There has been speculation here about software in the charging system. As far as I know it is accepted practice to have software written by different teams for triplicate software flight control systems. Because you can never positively prove a software system is safe. Does this apply in some way to the quadruple battery charging system. Not that 4 is a suitable number for a voting system.
