    3 Lithiums and 1 AGM

    Hey Guys! I have a question about my soon to be new power setup. i'll have 3 12v 100 amp hour lithiums for my trolling motor, along with 1 AGM for cranking and accessories. The Lithiums will come with a 4 bank lithium charger. My question is, can i charge the AGM along with the 3 lithiums with that charger? The charger has an output of 14.4 volts, and my AGM according to specs appears capable. Anyone have a similar setup?

    Thanks,

    You shouldn't, but you can. One of the problems is you need to unplug the AGM once charged to about 13V, versus leaving the charger on it and unplugging when convenient, as in the morning after plugging it in. Also, the chemical differences in the battery types and temperature requirements are different, so need to be monitored closely. Again, you can do it, but have to monitor it closely - really not a good idea.
