4-in-1 mini ESC max ratings
-
Hi,
I see here that the voxl 4-in-1 mini ESC is rated for 2-4s (i.e. up to 16.8V at max charge). Maybe this is a stupid question, but is it possible to run LiHV 4s batteries with this ESC? The max voltage would then be 4.35*4 = 17.4.
I realize this is above the rated specs, but I was curious if the difference was small enough that it was still within tolerable margins?
Thanks

Yes, using 4S LiHV (17.4V) on the mini ESC (M0129) is totally fine - the ESC components on the ESC are rated for at least 20V. The TVS protection diode will start clamping / conducting around 19-20V, depending on temperature, etc, which means if you exceed this voltage, the TVS diode will burn out - this is the first thing that will happen during a sustained over-voltage condition.

@Alex-Kushleyev Sorry for the delay, didn't notice the alert. But great, thanks!
