My own belief when travelling...as LIGHT and SMALL as possible. Battery grip defeats both those goals. An extra BP511, rather than a whole battery grip, are inexpensive when you buy Sterlingtek thru web, rather than sticking with Canon brand. You'll need a BP511 charger, with or without a BG cluttering and weighing you down.
[edit] Oops, just noticed you have one of the new fangled cameras that use that new form factor battery with a smart chip in it, not the BP511. I'm not conversant about aftermarket alternatives for the new battery type.
