Going to 300 seems like overkill, and shorter battery life.
The 300R is self contained, the rechargeable battery pack is built in. It recharges using my USB iPhone charger. We used it on 3 occasions recently for over 7 hours in the flashing mode and it was still working great. I have since charged it. We live in Illinois where the drivers do not pay much attention to motorcycles let alone bicycles. We wanted a really good bright daylight tail light and the 300R does a great job for US!
