I didn't think Tornado was fully FBW?

The PA200 Tornado is fully FBW with a mechanical linkage backup
system...

Then why does it need a thermal backup battery to remain airborn?

The One Shot Battery is there to provide electrical power to a Fuel pump (or
in combination with a Hyd pump). The engines also need electrical power to
keep their systems running - without electrics, the engines will "run
away" - Very bad thing if you're not near a nice big bit of tarmac......
