The relay is an excellent idea, lest you be looking for a boost in an abandoned parking lot
. I plan on putting a relay on my system and tying it into my taillight circuit since it's close to the grip heater wiring at the battery. So far though I've just been OCD about making sure I shut them off when I get to work... Lol, I even went so far as to make a small label with the labelmaker and affix it to my shelf on my desk. It says "Grips off?"
