    I have Arduino compatible gadget which uses 3.7 V LiPo.

    Since i cannot use any bigger LiPo, i would like to attach second LiPo to it, while it is still running from original battery, then take original battery out and put it to charger.

    This way i could swap batteries and it would run without interruptions. This is mobile project so i cannot use power from wall or computer USB-port.

    Is this doable somehow or does it fry the electronics?

    "Hot" swapping batteries could be an issue with some electronics, if this is a device you had built, maybe adding a large capacitor to the power input circuit may give you enough time to swap batteries without it "dying" on you.
