12 packs no different then a single pack. Just replicate the charging circuit
12 times with a single power supply. All depends upon the complexity of charger
you want. Simple case is just a resistor to provide more or less constant
current. Do you need an automatic shut off at the end of charge? If you do,
it's more complex.
