I couldn't find any battery choice in the manual that will implement this protocol.
Roadtrek uses 2 different tracers. there is one for lithium batteries also. it allows higher charging voltage. i think it tracer BN

I can't find any reference in the BN manual to lithium batteries. There is an assigned mode called "user" but nothing to describe what this mode permits. For maximum lithium battery life, my understanding is that the charging voltage is less critical than a shutoff state that removes trickle charging when the battery is considered by the controller to be fully charged. I don't see any way of entering this parameter.

There doesn't seem to be any user customer or technical support contact in the CONUS and my Mandarin is a little rough.

be that as it may -they do use 2 different tracers. one for agm and one for lithium.
