Regardless of how many years of experience, cross-wire incident happens very often. Reserved polarity is the #1 root issue in the RC industry. Although we can't control how electronics get installed, our high-performance ESCs now equipped with HOBBYWING patented technology.
Negative polarity protection.
XR10 PRO G2 ESC or higher, XR8 PRO ESC or higher model, AXE ESC series have equipped with a HOBBYWING patented technology "Negative Polarity Protection".
NPP does not protect from irregular current (ic) produced by a poor battery compound. Highly recommend using a quality battery C rating of more than 75C, less than 6 months old, always balanced and fully charged when use
