I have always had a 12 volt trolling motor, but am looking at a 24 volt so the 24 volt system is new to me. I know that 2 12 volt batteries in series make 24 volts. So how do you charge the batteries? Will a 2 bank 12 volt charger, one bank for each battery work? With a 2 bank charger do you need to disconnect the two batteries from each other to charge or have an on/off switch between or can they stay wired together in 24V and just hook up 1 12V bank to each battery? Do Li ion batteries make a difference here?So how do you charge the batteries? Hook bank 1 to battery 1; bank 2 to battery 2
Will a 2 bank 12 volt charger, one bank for each battery work? Yes, that is the way they are designed to work.
With a 2 bank charger do you need to disconnect the two batteries from each other to charge or have an on/off switch between or can they stay wired together in 24V and just hook up 1 12V bank to each battery? They do not have to be disconnected or have an on/off switch. Hook separate banks to each battery - bank 1 to battery 1; bank 2 to battery 2
Do Li ion batteries make a difference here? None whatsoever other than the charger must be compatible with lithium batteries.
