Why not just run a battery that weighs 85 grams more? You are already running a battery designed to be lighter than a full sized battery. typical shorty = ~200 grams, typical full size = ~300 grams.
You might as well gain the MAH/voltage advantage of a higher capacity battery to achieve your weight, considering it is in roughly the same location.
