It is time to replace those old 4d batteries that came with my boat. I recently read about Firefly Carbon Foam batteries. Does anyone have any experience with these? They are a type of Lead acid AGM battery that has some really favorable characteristics. I wonder if I can use my existing charger setup with a Carbon Foam battery. If so, would I just use the AGM charger setting? This question also applies to my solar MPPT controller as well. Can Carbon foam batteries be connected to the alternator output like a conventional battery? Ideally, I would like to use Carbon Foam for my house batteries and a regular AGM for a starter battery. Can these types be mixed in this way?
