    I am working on a project that I want to use a battery pack that is 7,4v 1800mah to power a board for a ecig project that has the below specs what would you suggest to lower the voltage to a safe level to run the board.Basically I gutted a Handheld radio and building a ecig out of it but wanted to use the existing battery so this would be rechargable and have same look and feel as if it was still a real radio.....

    EVOL DNA 30 Board Specs
    Output Power min7 Watts max30 Watts
    Output Voltage min 4 Volts max 8.3 Volts
    Output Current 10 Amps
    Input Voltage min 3.2 Volts typical 3.7 Volts max 4.3 Volts
    Input Current min 1.5 Amps typical 6.0 Amps max12 Amps
