I'm making good progress on the new #LiFePO4wered/18650 base for Pi 3 versions of the LiFePO4wered/Pi, see this project log.

Meanwhile I've been doing some stress testing on my first prototypes. I've been running a Pi 3 at 100% CPU for 5 days straight, powered from the prototype (plugged in of course), covered with a box to contain as much heat as possible, and it's been rock solid. Yay! :)

So now that I have a new prototype that is pretty much identical to what I intend to run in production, I'm going to do the same test with it:

First I'm having the battery run out, then I'll let the system charge while under high load for a week or so and see if everything behaves well. If it does, I'll go ahead and order production panels.
