With this simple mod once your battery reaches a certain level, the battery indicator LED will start blinking for around 15 seconds every 1 minute. You can set the voltage at which the LED start blinks by shorting out the “Set” contact on the board for 2 seconds when the battery is low.
Connect the board to power, one wire to the LED and you’re good to go. Works with AAs, rechargable AAs or LiPos (only for DMG).
