Would you use any of the lithium batteries for initial hi current demand tasks such as electric pylon deployment and self-starter motors?

I would (and do) use a properly spec'd LFP for that purpose. However saying so will start an epic chit fight on this thread like the other ones. So it would be best to live in the past and use whatever your copyright 1995 flight manual says to use. Don't do so unless you are familiar with all the issues and able to make a proper engineering call.
