Title: Battery Status Indicator
Post by: Remzi 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 (https://www.ebay.co.uk/itm/LED-Power-Indicator-Capacity-Tester-Display-for-3S-11-1V-Li-ion-Lithium-Battery/282368486578?hash=item41be792cb2:g:mXoAAOSwnHZYTms3) 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 (https://www.ebay.co.uk/itm/5x-RGB-LED-Rectangular-Common-Cathode-Diffuse/182677916285?hash=item2a8873ca7d:g:JcMAAOSw2ZxZcS8P) 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.
