It will NOT protect the components on the circuit board(s) from short. It Takes an overload draw (like a short) on the load side to puddle the fuse. By that time, you've already crispy crittered some of the components on the board....
STILL, it is a good idea. may save your tank from turning into a flaming pile of plastic (not to mention the battery).

Too right. A transistor is the fastest fuse known to man.
