We're not talking about brown outs here...we are talking about all-out BEC failure.
MOST ESCs that I have run in the past, if you exceed their rated amperage, they will brown out, but after a few seconds, or after power cycling the ESC, the BEC resets itself and things work again. I actually found out that I was exceceding the mechanical endpoint on my steering with my rally car this way. (things were fine when on a car stand, but when the suspension compressed, the arms pushed back against the servo....setting my endpoint 5% less solved the problem)
But with the SXX V2, once you blow the BEC, it's done. No amount of resetting or updating the firmware would correct it....
Most ESC's have that 3A limit, but if you exceed it, it behaves like a battery running out. With the SXX V2, if you exceed the 3A limit, it's toast.
The painful thing is that more and more servos are coming out with more and more speed, more and more power, but very few of them rate their current draw....
The replacement board:
MOD + STOCK UPGRADE
Note specifically the comment of "Moreover, the Upgrade-Kit SXX „Mod + Stock“ fixes the existing problems with the BEC of the SXX V2."
Known design flaw.
I am not calling out bad product, I love my LRP stuff. I just want to make sure that anyone running the SXX V2 has the best experience possible. It's not a cheap ESC, and to have it fail really sucks, so get the upgrade!
