Nope. You can use a setup like Method's HVC/LVC built into your pack, and just bulk charge at the same voltage and configuration you ride at. Every so often if you like you can check balance at each of the paralleled balance plugs on the little boards, using your choice of devices from multimeter to Battery Medic or whatever. If they're out of balance enough to warrant it, then use the BM or something like it to manually balance the cells.
If you're not running them down very far most of the time, they're likely to stay in balance pretty well if they were already cycled and tested good and equal to each other to start with.
But if you like, you can also do parallel-series conversions for each charge...it just adds a slight-to-great potential for disasters like SoSauty's (where the entire pack was destroyed because of an accidental cross-connection), depending on how you setup your changeover from charge to ride and back. It's possible to essentially idiot-proof this kind of setup, and not all that hard to do so. But if you don't do that, then it's possible to misconnect things and cause bad stuff to happen.
I'm sure it's possible to cause bad stuff the other way, too, but I suspect it would happen less often and be less disastrous.
So far all I have had to do is bulk charge, but I don't take the pack down very far, and the one I'm using at the moment isn't RC LiPo, but soon I will be using that, too.
