On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won't be voltage drop between battery and main board. 694 694 ))) 695 695 696 696 697 - 698 -=== 2.8.4 Replace the battery === 699 - 700 700 ((( 701 -The default battery pack of N DDS75 includes a ER26500 plus super capacitor.
