I just read on another site a recommendation to use a 15 amp charge controller to charge a 12 volt battery from a 24 volt bank.
Any thoughts on this practice?
Thanks.
Charging a 12volt battery from a 24v battery will work but seems counter productive and inefficient.
Better to have a 24volt battery system with a way to convert the 24volt to 12volts maybe using DC - DC power supplies. I haven't really looked into that type of hardware but someone else may chime in with their experience.

Here is a link to a 24 to 12 VDC Dc to DC converter. From 5 to 40 amps. Not sure if you want to go this route.

Thank you for your input.
It would seem to me that charging a battery that is already installed to support 12v loads would have some merit as it will support short duration, high current loads that a 12v converter/ equaliser won't.
That said, if I knew the best answer, I wouldn't have asked the question.

A potential problem with that will be to find a 12V CC that will be efficient in charging a 12V bank from a 24V bank. Many MPPT or PWM CCs will not work with battery input, since they expect a current limited source. A PWM CC would also lose 50% of the input power.
