I found this when looking for a refresher between the two:
In your test, did you recorded current at take-off, climb and horizontal flight?
I just want to build up a battery pack and I’d like to know specifics to correctly dimension paralleled and series cells.
If I’m not wrong max. thrust of x4 is 60kg at 350A . Somewere in the post I’ve read 137A horiz. and 300A take-off. So I suppose 25-27kg of thrust @ 137A is enough for horizontal?
I didn’t record these values. You’ll want to make sure pack can handle 300 amp as this is what it draws at full power. You might want to consider taking the power from each end if the pack to lessen the load on the connectors as well so you’ll have two positive two negative connectors.
