I bought a Orion 12/24-10 converter, and installed today with intention to charge my 24v lifepo4 battery from the van. The lifepo4 battery was measured at 26.4volt and I set the Orion output at 27.3 volt. I was expecting the battery to draw the full 10amp from the van, but it turned out the charging current was close to zero (at 0.25amp). With that, this unit can not really serve as a battery charger as claimed in the user manual. Did I miss any setting? Thanks for any insight.
