Thanks for your input. It does look like mine was faulty from new. No big deal though, as I'm always with the batteries on charge so I'll just charge separately.Mine works correctly. It does not charge the one with the least charge first. It charges the one with the highest charge first. If I add another battery to the hub with batteries already on it, the charging of the battery currently being charged is momentarily suspended until all connected batteries are re-polled, and then the one closest to full charge starts charging, which may or may not be the one that was previously charging. Goal is to get you a fully charged battery as quickly as possible.
