Hi everybody,
I have a project which needs to power up from Li-ion or LiPo battery. I have never designed a pcb with battery and its management.
All the things on PCB, uC or other IC(GNSS, current limiter etc.) supplied with 3.3VDC
It should work as like this,
- When there is power, it should charge battery and supply voltage to ESP32 and GNSS receiver.
-If battery is fully charged, It should cut-off battery charging.
-If there is no power, It should supply power from battery.
I need to use battery with 6000-8000mAh capacity, and hard to find high capacity battery. Is it possible to use 18650 - 2000(3000)mAh battery in parallel with BQ24030 as 1S3P or 1S4P?
I couldn't understand output voltage of OUT pin. Should I use Voltage regulator?
Thanks
