If anything, you are just being kind to your packs. My guess is you probably have some good packs and aren't pushing them to their limits, so they don't drop voltage under load enough to send you into LVC.
Heck, it only take a few minutes to change it to 6V, you might see how it does. Won't hurt anything, that's still a conservative setting.
