This system isn't regulated.
To use that it must follow next steps :
1. Plug the system to the USB NOT to the charge yet, and set voltage to 0V
2. Estimate voltage to your charge with the number of battery. For example 2 batterys = 2 x 1,5V = 3V
3. Plug the charge to the terminal block.
4. Set the voltage with the potentiometer.
