Hi,
I'm currently thinking of extending the battery life of my quad by powering each motor and ESC individually. I will be using 1 dedicated battery for each motor, and 1 dedicated battery for the flight controller itself, bringing the total to 5 batteries for the entire quad.
My thinking is that by powering each motor with a dedicated battery, given a power draw/consumption, the flight-time of my quad will be increased by 4x as each motor will have 4x the capacity to draw from. Putting the problem of weight aside, would this be a feasible idea?
Also, i am currently using just 1 battery to power all motors, and as such, i only have to plug in the single battery and i can calibrate my ESCs. How would i calibrate my ESCs if i am using dedicated batteries for my APM 2.6 and each motors?Would i be able to get away with powering my APM using the BEC on my ESCs?

Not convinced there is any advantage. It will probably be heavier over all even if you quarter the capacity of each battery compared to you one, especially with the extra bat for the brain. More points of failure.
On a quad of a battery fails its still going to crash as it doesn't have redundancy.
Also means a power module feed volts and amps to the brain won't be available, so no automatic battery monitoring, alarms fail safes.
Flight times will still be dictated by the heaviest loaded or weakest battery.
I am looking at using 2 for an octaquad, but that has inherent redundancy to cope of a battery fails.
