I believe the first Etreks only delivered with 8 AGMs with an inverter-charger by AIMS. This was followed by the AGM or lithium option that employed the Powerstar (aka Microgreen) inverter with 8 charging protocols that didn't include a lithium selection. However, prior to RT's demise I think Etreks delivered with batteries and inverter-chargers from KS2 which included an additional protocol for lithiums.
The AGM-1 setting on the OP's offering isn't theoretically ideal but practically it is quite acceptable. We've been using the AGM-1 setting on our ETREK lithiums for over 5 years with no issues.
