Amps in tens are completely irrelevant for bike lights, so you can safely disregard those Amp numbers. The only potential application for high current for a single cell would be to power a high power horn but even there you would not go above 10A. I doubt this box you plan to use can carry out a higher current and this from some cells connected in parallel. Look at the capacity only. I have no personal experience with Molicel, but I see that they have some reputation.
