I am referring to the charge controllers each trying to "smartly" charge the batteries from different sources. Obviously not an issue for the chassis source (which is dumb) but on shore power with solar charger and inverter/charger on line together they each try to smartly charge the batteries. Bottom line you can overcharge the batteries.I guess I am unclear about different charging sources "fighting" and "battling".
Ideally any battery set should have a smart controller which looks at all sources of charging current then applies the current to the battery set smartly and appropriately to the battery type, irrespective of what current source is currently on line.
BlueSea acknowledged the need for such a device and claimed to be working on it.
