you could use a cell holder like above and stick a plug on it for the light but you will have no protection that way or use it with that lcd batt cut off meter with it then it will cost less than 5 quid.
tho if you went out and bought these ready made in a pack would cost 80 quid and there only 2600mah.

so 20 quid for 4 batts 2 free lights and 10 quid for the box is a lot cheaper and will last longer just not look as good.
over 12v then i can use a dc to ac converter if i needed to so if we had a power cut could use the pack for that and plug the tv ect in to it
