Hi,
I just bought a Cyrix-ct 120. My startbattery is a couple of years old sealed lead acid battery and my house battery is a brand new AGM battery.
My alternator is connected to my start battery.
I also have a solar panel and an MPPT 100/20 regulator which is connect to my house battery.
Is it OK to have different battery types connected to the Cyrix, or will I damage my batteries. For Example the SmartSolar MPPT is det for AGM charging, hyras This voile potentiellt over charge my startbattery since Cyrix is bi-directional?
Also do I risk that my older startbattery will wear down my new AGM battery the the breaker is closed due to solarcharge or the alternator?
