I built something that's similar to what you're describing, here's an article about it: https://www.hackster.io/lukehaas/e-ink-display-for-daily-new...

It combines a Pi Zero with a 2000mAh lipo, updates every 6 hours and lasts for around 90 days per charge.

Thanks I like the idea of a git pull on boot up.
