I don’t have one of those, nor do I have enough information to know the answer — but I’d personally be much more worried about the proximity here than that capacitor bridge.
If that bridge is wrong, you’ll know right away and it won’t ever work. (Only a financial loss)
If that solder blob is too close to the FET pins, it could work for long enough to get into a high-speed braking situation, then blow up. Which is far worse. (Possible bodily injury)
But it may not be too close. Without this in my hand, and without the files for the PCB design, it’s real hard for me to say.
First time you plug it in, maybe do it through a fuse. And/or check continuity with a multimeter on the ESC+ and ESC- wires.
