You probably mean an XO-1, which uses the same battery as XO-1.5 and
XO-1.75.  There's no such thing as an XO 1.0.

Yes, the battery can feed an external circuit directly if it is not
feeding the XO, but the battery capacity will begin to diverge from
actual state of charge, and that may cause unexpected shutdown.

Therefore I do not recommend you use the battery to feed an external
circuit directly.

No, the battery cannot provide 12V alone, the battery voltage is too
low, but a DC/DC converter can be added.

No, the XO-1 does not provide 12V output, but does provide 5V output via
the USB ports.
