BananaPi basic case with battery and wall mount

thingiverse

I utilize this BananaPi m1 as a headless server installed under my desk. Expanding space for a pair of affordable 18650 batteries enables me to harness the built-in charger, creating a handy little UPS for it. The eBay specialty batteries are marked 6000mah, but they actually have only 1800s capacity - a clear example of the importance of doing your research when buying. Since I operate this machine headlessly (using only USB for power and Ethernet for access), I still achieve four hours of run time on battery. For assembly purposes, I employed: Four M3x5 self-tapping screws to hold the BPI in place. Two M3x8 self-tapping screws to secure the battery pack bar. Four M3x16 bolts to attach the two halves together (after threading the holes in the bottom with a 3mm tap).
