If a device need 5amp to work for 1 hour and the battery is 25amp. We assume the setup will work for about 5 hours and then there will be no more energy in the battery.
If we do the same thing with T200 and BR batterie and do this in a conservative way, I reach very low running time. See: If I have 6x T200 running at only 3A out of the 16-20A full throttle figure (thus about 20% max speed), the 6x T200 would need 18A total. With the BR battery, this is 1 hour or run time.
Is this what the users experience? With 8 thrusters, the heavy configuration would then last only 45 min. Where do math and user reality meets up?
