Maybe my power supplies are on the odd side, but with the volt adjustments minimized the whole works returned 167 volts, right on the money for safe pack charging/rebalancing as-is. I know 42*3+48=174, but there seemed to be extra adjustment room in practice with the units I received. I realize charging/rebalancing as it passes 165V or so would get rather slow, but that would minimize heat buildup. At 162V at least the power supply consumes the same full 63W it does at lower pack voltages.
