Low Battery Blinking LED Indicator Mod for DMG / Pocket / GBC

$8.00 $6.00

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” solder pads (e.g with a screwdriver or wire) 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. You need to supply your own wire.

DMG
– Works with rechargeable AAs
– Will work with LiPos as long as they don’t have fixed voltage output (some battery packs you buy do this)

Pocket/GBC
– Works with AAs or rechargeable AAs
– Requires modification to work with LiPos as long as they don’t have fixed voltage output (some battery packs you buy do this). By default the LED is too bright when the battery is low so you won’t notice it blinking. You could fix that by changing the resistor labelled R7 to around 4K-5K.

5 Oct 2020 – Working on v1.1 which should be able to handle fixed voltage output LiPo battery packs, will require soldering to the battery connector on the pack and the power switch.
