Battery Status Indicator
« on: October 14, 2019, 09:55:25 PM »
We need to know how much juice left in the internal battery pack.
So I bought this 11.1V Li-Ion Battery Status Indicator of ebay.

I removed the LED lights and the top of the switch.I shorted the switch so it will always be lit.

I also bought rectangular RGB LED's of ebay.

I soldered the LED to the indicator board.Added 330R resistor to the negative leg.

I added a connector to the +12V input of the voltage regulator for easy plug in.

It's ready to plugin.

Push it in where the original LED was.Perfect fit.

It turns red when low on power,green medium and blue is fully charged.
