Re: Visual LEDs for LiPO battery

Hi yellowfish, Would you like to try this flowchart and let me know it is ok for you or not please. One thing to consider: You could some some battery power by powering LED's via PWM at say 1KHz. All you would to is for flashing is alternately change duty between 0% and 90% for example every 500ms M...

Hi Martinus,
Your welcome, glad I could help.

Yes I would probably use a potential divider.
Something like this:

Re: Visual LEDs for LiPO battery

Yes it does make sense. There are two ways I could think of. 1) is use aswitch DPDT switch on your circuit. So one side of sw connects the two resistors in parallel, while the other side of sw is used to let microcontroller know that the lower voltage power pack is used. That way the flowchart can b...
