RE: Lipos in parallel ?
the battery C rating should be greater than or equal to the motor draw in that table (since i already figured out the 80% in the table)
about that other q, I would think if you are getting the ESC's to arm correctly and you have the 1 BEC disabled, you should be good to go
You can only divide one or the other if the original single battery is properly sized. So you either divide the mAh rating or the C rating by 2. If you divided them both by 2, then the total cont discharge would be divided by 4
