simulate this circuit – Schematic created using CircuitLab
Here is a thought (hopefully) to my grounding/shorting problem (Multiple ground).
Would this circuit work being fed by the li-ion cells to obtain an isolated +-3.7V? What kind of transformer should I look for? Like key parameters. (please don`t mind the values)
NOTE: I realized that i drow the two ground connections the same, please refer to those as two separate GND connections
