I have a Phoenix 12/50 charger with 3 boord-net batteries of total 240Ah connected. I also have a starter battery with a bow thruster battery in parallel which totals 2x70=140Ah. As the trickle output is limited to 4Amps I would like to connect the starter/bow thruster battery to output no. 2.
I understand that the Phoenix devices the charge current over de 2 outputs. Is the unit capable of doing this even with 2 output that are not equal (240 versus 140Ah)?
Then there is the configuration. As I have to reprogram the charger current, what current should I use, just the total of the 240+140Ah, or use the minimum current, boord-net bat or starter bat.
