Question:
I have a solar setup in a shed with lithium batteries. Would the optimate smart battery charger work to use the lithium batteries to charge and maintain a lead acid battery in a tractor?

Hey Kerry, yes the Optimate DC to DC charger part # MA99JR that you referenced would allow a lithium battery to charge a non-lithium battery. So your solar panel charges the lithium batteries and then from there you'd want the lithium batteries to top off the tractor battery?

Hey Kerry, how did things go using the OptiMate DC to DC charger with your solar setup and tractor battery? It’d be great to hear if the lithium batteries were able to keep the lead-acid battery topped off. Your update could make it easier for others working with mixed battery types.
