so when i had wired up my saber, everything was working great, sounded amazing, led was and still is bright. but for some reason now my rechargable batteries are only lasting UNDER a minute!!! the saber makes repeated swooshing sounds then shuts off. when i pop in a fully charged battery i get the same problem.

is it possible my batteries have drained even tho they are apprearing to be fully charged?
my saber does NOT have a kill key, could that be the problem?

as i said before everything was working perfectly months ago when i had first assembled everything lol

any help would be great thank you! =)
