The reason not to use the DDA/Optimate connector is that it's permanent 12v direct to/from the battery, the grip connector is switched by the ignition key. If you have a transformer connected to directly to the battery it will gradually drain the battery, albeit very slowly. I had a tracker on the the bike so had to keep it on an optimate via the DDA connector anyway.
