I use a mobius V2 (500mAh battery) for my commute with a waterproof case. It manages the 45min ride in plus the 45min ride home, but I tend to give it a bit of a zap during the day to be sure it lasts. It does the loop recording mentioned above as well as timestamping, and the footage quality has been great.
Looks like you can now get a newer V3 model (820mAh.. '2 hour' battery) for £70 with the waterproof case included here
