You´re right.
That´s why I have my electrical instalation arranged in such a way that, whenever I´m no t on board, neither the regulator nor none of the electrical appliances on board are connected to the battery leaving only my small solar panel directly connected, in order to keep the cells topped up.
In addition to this, my electrical switch arrangement only lets me charge the batteries whenever the electricl panel is switched off the grid (by means of an SPDT switch), to prevent any current spikes from the alternator to damage my auto-pilot, bidata, etc...
