I mean yea, ok, it makes sense inside the battery to point from + to -, but what the physical meaning of being opposite to the current flow (or the E-field inside the wire) is?
For the sake of simplicity let us assume movement of positive charges and forget about electrons. Whatever we state for positive charges can be just reversed in direction to follow the reality. But since all books consider the positive charge convention, let's stick to it. And the sketch I took from a video assumes positive charges.
