| Nov 30, 2021 at 17:51 | comment | added | user57037 | Will the ESC operate the motors in regen mode? Normal power supplies cannot sink current, so there is risk of damaging the power supply if you try to go in regen. Generally running multiple ESC's off of one power source (battery or supply) should be OK, but 30 A is a lot. You need good connectors and good cables. | |
| Nov 30, 2021 at 15:17 | comment | added | user16324 | If each motor requires 30A and your power supply is limited to 30A, you can only run 1 motor at full torque at once. If that's acceptable, enforce the limitation in software. That's fine for a crane or robot, not so much for a quadcopter. (Which must lift a 120A supply) | |

| Nov 30, 2021 at 15:14 | comment | added | Stiddily | @DKNguyen a good 30A power supply is expensive. You can get a lot of power supplies in that range for dirt cheap. The quality shows though. | |
| Nov 30, 2021 at 15:11 | comment | added | DKNguyen | A 30A voltage-regulating, current limiting supply is really expensive. By all means get one if you can actually afford one. Your money is better spent on an oscilloscope if you don't have one yet. | |
| Nov 30, 2021 at 15:05 | comment | added | DKNguyen | You should have you learned about parallel connections by now. So whatever happens there with one real world caveat: Real batteries and voltage supplies have a series internal resistance so the more current you draw, the more voltage will sag. If you have not learned about series and parallel yet, go read about it now. It's more important than your immediate question. | |
