I have 18650 battery shield with 4x 18650 batteries, that is giving power to my ESP32 and its been working fine. I would need the system to be always working and easily chargable as it is in place that have no electricity.
I was wondering would it be possible to have power bank which would be giving power to that 18650 shield so every couple of weeks, I could just go and swap the power bank and system would work?
That propably is not the most smart thing, but it is in place where my friend is always making the change so I was thinking that that would be easiest way. I could build closed system which battery bank would be on some place that its easy to took out and put other on its place.
Is this possible?
I would say you should incorperate a battery charging system in your design to relief you of stress
