Custom Bicycle light Power questions

I have 2 maglite mini AAs, each one normally runs off of two AAs for a total of 3v each, and 6v between the two. i was wondering if i could hook the both up to one 6v battery pack or would the higher voltage fry them? I only want to wire them to one battery pack for ease of charging, because i am gonna mount the lights semi-permanently on my bike, and i want to be able to charge the battery easily. Message me if you have any questions, thanks in advance for your help! I really appreciate it
