    in reply to: 600w step up converter #12443

    Hello Roman,
    Thank you for your writing in.
    We are sorry for keeping you waiting.
    Regarding to your first question, the battery you connect must be discharged fully before you connect it.
    About your second question, you should connect a switch on the input terminal of converter, when you want to turn off converter, just through the switch.
    The next time you still need to again set the current limit when you want to turn on it.
    Hope this can help you.
    Best regards.
