I have a multiplus compact connected to lithium drop-in batteries and the supplemental output from multiplus to the starter battery. I would like to add charging from alternator to lithium batteries through the Orion tr dc dc charger. Question is will Orion tr start to charge the lithium batteries when connected to shore power because the multiplus will charge the starter batteri and by that increase the voltage on the starter batteri. I would prefer to only charge through the multiplus when powered from shore.
1. is it at all a problem to have both the multiplus and Orion charge at the same time.
2. will the Orion tr start charging, it only receives 4 A from Multiplus.
