Battery Charger
My 2015 Axis charges both the house batteries and chassis battery when it is plugged into shore power. There should be no need for a auxiliary 2 amp charger. I have verified this with a volt meter. When the Axis is plugged into shore power the engine battery and house batteries jump up to 13.3 volts. A fully charged battery on its own will only measure 12.7 volts at rest. I believe the converter has 3 charging rates Fast, Medium, and Slow just for maintaining the batteries at full charge. Its a good system if it works properly.
