Soon after purchasing a motorguide dual on board charger 15/15 I upgraded my trolling motor to 24 volts. The convenience of charging my two sole batteries was short lived now that I have three. Can I wire up the dual charger to simultaneously charge the third starting battery without damaging the charger? If so, how of course with the understanding that I will be losing efficiency since its now charging three batteries instead of two. Or should I just updgrade to a thre bank charger?<br /><br />Thanks in advance.
