Like Matt says, if you go with a 3S pack, you just have to dissipate that extra 3.7v or 4.2v with a full charge X the average amps, say 3 amps as heat.....that is up to about 12.6 watts and that's allot of extra heat.......ever pick up a 10 watt light bulb that's been on for a while.....puts an added stress on the output caps as well which may well lead to less stable regulation if they are not of large enough capacity....also, whichever regulator you choose, be sure to get one with 18 ga input and output leads, rather than the 22 ga that some are using......
