Helpful Expert Reply:

You don't want to mix lithium and lead acid batteries in a battery bank. The reason being that the lithium batteries have a higher resting voltage than the lead acid batteries so the lithium battery is going to be drained constantly by the lower voltage of the lead acid battery. Your best bet would be to go with all lithium like the # PS44FR that you referenced.
