controller transistor traces

[OtitisRex]

i’m gonna go wide on this ledge, and guess that traces on the back of the controller board for either source or drain idk of the FET banks should be a little more… full?

the weird part is this controller was wild brisk. it was a 12 FET go-getter after a mild shunt. only on autopsy did i even see these

That's the most piss poor soldering job i've seen on a controller.

I would totally beef that up and any other power traces, if you are pushing the controller past stock at all.
Another upgrade for many controllers is to boost the gauge of the phase wires if it's inadequate - another place where a lot of controller power loss happens.
