    just wanna add something,
    this would have been better if there are indicators that :
    the batteries were compatible or still capable of being charged
    the batteries were charging
    and the batteries were fully charged.

    How can I be sure on how much current is this improvised assembly getting into the batteries? Is 5V the correct voltage to charge 2 x 1,5V NiMH batteries? Will this be a quick or a slow charge? How will this affect to the wear? What USB charger current are you using? Is there an overcharge or temp protection? ... And finally: is it sure to use?
