Yes you definitely need one. If you remove the battery your car's
computer will delete all its programming and you will never be able to
start your car again without getting it back to the main dealer for a
repair costing maybe £1000!

You are now powering your whole car through those two little pins on the
OBD connector. You will possible do more than £5 in damage if it draws
too much current.
