Hello !
I have an all in one pc project with raspberry pi and a screen with its controller
the RPI uses 5V 1A max
the controller uses 12V 4A max
I use voltage step down to convert 12V in 5V
I have battery capable of delivring 5A (wrong mAh on aliexpress) as well as a power supply with the same caracteristics
How can i build a system that :
- when the power supply is connected, it supplies the RPi with the screen+controller; otherwise if the power supply is not connected the battery power my system.
- When the power supply is connected and the battery is not charged, the power supply charges the battery.
Have a good day
(sry for bad english,i'm trying my best)
