Ideally I want lights that can comfortably be used for 3 days, because then I can charge everything up on Wednesday then on the weekend.

I personally feel that it's absolutely essential for me to carry backups for both front and rear lights. I have an Ultrafire torch and a Cygolite Hotshot as spares with me all the time. Absolutely vital in the winter. If this is for summertime and especially if it's just for occasional "Stayed at work too long, now it's getting dark" use then you probably don't absolutely need backups. But if you do have them only for emergencies, be sure to check that they actually work once a week or so.
