Hi All I am new to this forum. I've bought a boat with a Blue Power IP22 12/20A 3-output charger already fitted. One output goes to my single starter battery, the other goes to two domestic batteries.
My question is; which of the outputs does the charger use to determine when to switch between charge modes?
My starter battery is usually full but the domestic batteries can run at a lower state of charge. So I'm concerned that the domestic batteries will not be fully charged if the charger is using the starter battery voltage as an indication of when to switch from Bulk to Absorbtion.
Voltages at the charger terminals are identical - is this because they are all simply connected together? Or maybe they have some simple isolation by means of an internal diode?
Thanks for any answers!
Karl.
