    SD-Card not working on Teensy 3.5 with LiPo Battery

    Hi,
    if I connect my Teensy 3.5 to a 3,7V LiPo Battery (1000mAh) "card.begin" fails (testing with SdFormatter example) with
    "SD error: 40,10001" or "SD error: 43,20001".
    When connecting the Teensy to USB-Power everything is fine.
    Also tried to reduce CPU-speed of Teensy - but without success.
    Any suggestions?

    P.S.: Apologize in advance if I don't follow some rules of this forum - this is my first post.
