I have a small fishing boat with a 24v trolling motor fed by 2 Battle Born Lithium Iron Phosphate batteries and a 12v AGM starting battery. I would like to be able to charge the trolling motor batteries with the alternator when under power and solar when sitting at home. I would love to use something like the Renogy DCC30S, but with the systems having 2 different voltages I don't know if this is possible to run a battery in series for discharging and parallel for charging.
