If that is really the cause, software may be able to help to recover by detecting brownout and reconfiguring the Jaguars if necessary.

I really do like this effort and the value it adds.
However, there is a slight catch. If the system often browns-out the problem will degrade the battery charge and possibly the battery life.
So this is absolutely great for situations where something unusual happens and the drive train is operating within a reasonable range, but it's no fix for a drive train that often draws too much current under normal operation. If a drive train can't move forward on a flat rug surface without any interference and without flowing 60A all this will do is buy you a little time. Maybe you can use it to extend things to the end of a match for a design pushing just past the limit but it'll have consequences later.
