I would assume this battery is for a ups like function.
And I just noticed something about the armbian release of stretch
available on the pine site. The initial login is as root, meaning one
can probably addusr his own named account as user 1000. This would
solve several problems I believe, so I have that image coming in now,
and if I have time later today I'll burn it to an sd card and give it a
shot. It can't be any worse of a C.F. than the ayufan builds with its
pre-allocated user 1000. Probably defaults to dhcpd for a networking
hookup, and I do have a 2 machine wide server setup in dd-wrt that I can
edit to give it the same address because dd-wrt can bind the address it
hands out to the M.A.C. address of the interface asking for a lease.
In the FWIW dept, I am not powering it thru the coax plug, but tied
directly to the 5v and ground on the headers. Reason? I wasn't sure the
plug I had available to hook up a 5 amp supply was of the correct
polarity. I may verify that with an ohmmeter as the current method looks
like shade tree engineering and could short if miss-handled.

More than likely a much bigger, rechargeable battery like the pinebook
would use.
