Multiple Linear ESC in MWC ?

Post by Amefuri »

Hello,
I have been wondering, is it fine if I connect all 3 or 4 ESC in parallel ( Turnigy Plush- 10A ) wich have Linear BEC output 5V/2A on my Multiwii Crius v2.5 using LiPO 3 cell battery ? Will it not burn my board ?

The board doesn't care, but the ESCs may get unneccessarily hot.
It only takes 10 seconds each to pull the red wire out of the servo plug and stick some shrinkwrap over it.

Thanks, so if I want to power the MWC board and receiver at same time without connecting 5v wire from ESC in parallel, I could use one 5v for board and another 5v for receiver? And of course not using the + pin for mwc and receiver connection and using same ground? Would that work ?

By the way, could you explain why the board wouldn't care about parallel connection? Does it have some kind of protection or its the ESC who understand how much power they need to give and they save other unnecessary? So they become hot. Is that the logic behind it ?

A device only draws as much power as it needs. You can't force-feed it more.
