Once the Multiplus is in float mode, its output is set to be 13.60v. My motorhome is on shore power. When the DC load on the Multiplus drops from 15A to 5A, the Multiplus' output voltage rises to 13.65v (as measured by the BMV-712, and a Fluke DVM). It will eventually get back to 13.60 but very slowly. And then when the DC load current increases from 5A to 15A, the Multiplus output voltage drops to 13.55v. Again, it will eventually, slowly, find its way back to 13.60v. But these voltage fluctuations cause current to go in and out of the LiFePO4 battery (as per the BMV-712), which affects the BMV-712's capacity algorithm. Is there something wrong with the Multiplus that it can't hold a solid 13.60v output? My old power supply / converter could. Any insights would be appreciated... if it's defective, I'll make an exchange.
