Can I charge lithium and AGM batteries simultaneously or do all the batteries have to be lithium or AGM/Gel etc? I have good AGM but want to start replacing with lithium as they fail. I am looking for a charger that will allow me to do this.

Hi @Barry Venter

The batteries connected will all get the same charge profile, so mixing different battery types is not a good idea, especially lead + lithium because of the big difference in charge profile.
