I want to build some small packs to run some of my DC items if the power goes off. The main things I want to run are the wireless wifi mesh nodes for my network and a wireless hub for my weatherflow tempest wx station. Ideally I could keep the internet and wx online in a power outage. The weather hub runs on a simple 5v 1amp micro usb plug and only uses a few wh per day. The mesh nodes run on 12v and I haven't measured their power consumption yet.
The pack would have to tolerate being plugged in 24/7. I was thinking a 4s and maybe 2 or 3 in parallel. I would use dc-dc converters for each device that I need to power. I'd like to keep these small and simple. I can 3d print the cases if I need to do that. It might even make sense to use a jehu style pcb mount for this.
My only real concern is having a charger plugged in all the time and not pulling power off the cells.
