Hi, I'm looking to upgrade my on board charger. I have what i think is a 2 bank charger for two 12 volt batteries hooked up to 24 volts for a trolling motor. I added another deep cycle battery for stereo and electronics. I aslo have a 12 volt starting battery. I would like to charger the 3 deep cycle batteries and if possible the starting battery. Starting battery is not really a concern but would be nice. So basically I need to charge 3 batteries. One is just a 12 volt by its self and the other two are hooked up to 24 volts for a trolling motor. Can someone point me in the right direction to what I need. Thanks
