May I be advised on powering cheap lasers from this device? Answered
I've got a "6V" SLA connected to it's original charger.
It's currently driving a motor with a mirror glued to it, I want to add a couple of cheap laser modules to the same power supply.

>No load voltage is less than 6V
>When running the motor the voltage across the terminals is less than 5V
I do have a couple of UA79M12C -ve voltage regulators, and think I should use one.
The cheap lasers are built to run from 3 button-cells (~4.5V)
