Transform 5 2xAA battery power supplies TO 1 power supply
Multiple problems.


Those are not led, they are EL wire with an inverter.
That battery pack expects Lithium cells, of the 18650 type, not AA alkaline or nimh or nicd. (I don't know if you are aware).
They will pull what they need so do not worry about having a power source with higher capacity or current sourcing ability.
You can use a voltage regulator like a buck or step down regulator to bring any of the voltages down to the 3V the inverters expect.
