I did some reading on chargers and found the wikipedia page that explained that a "simple" charger either uses constant current or constant voltage, but may not be the most efficient... would it be reasonable to string 9 batteries in series and simply apply a wave-rectified, capacitor-smoothed wall outlet voltage across them? Sounds absolutely insane to me. I'm just thinking, if I had a 12 battery pack and had a dpdt switch that could make them either 2 parallel strings of 6 or one series string of 12 (not a difficult switch to imagine), then i could use a very gentle step-down transformer and a couple big capacitors to charge them...

again... sounds crazy to me, but that's what i gathered from a "simple charger" description.
