Hello, I'm powering a raspberry pi 1 (model A) from a small power-bank. I read somewhere that doing this will put my sd-card in danger as it might get corrupted when the power-bank is running out of power, so I need a way to directly and completely cut the power supply when the voltage levels are getting low.
the idea is to put a ~ 5v relay on the power-supply from the power-bank to the pi, so that when the voltage drops, the relay are cutting the power, will this be a working solution, or are there any better ways to check for low voltage on power-bank powered pie's ?
the sd-cards seem to be corrupted when the pi is running on rly low voltage, not when the power is cut of the pi (eg. pulling the plug).
