Can I convert a 3.6V battery into 4V? Answered
I am planning on using an A9G GPS tracker, whose working voltages are 3.5-4.2V. I have a mobile phone battery that would be perfect to power the A9G, but it's voltaje is 3.6V, so if it goes down a little bit, the A9G won't work.
So my question is: Can I convert the battery voltage to constant 4V or so? Because I feel like if I connect them as they are, once the battery goes below 75% or so, the A9G won't work.
