Before you do, you should be careful of how much amperage your auger will draw versus how many amps your ATV will produce. Many motorcycles and ATVs do not have alternators equipped to handle a large amp draw for things such as auxilliary lighting, or electric vests or heated handgrips. Also, the battery in your ATV is not suited for a huge current discharge. If you draw it down too much, you will dramatically shorten the life of it (the battery).
I used a rechargeable auger last year a few times. I don't remember the brand, but I liked it a lot! I really can't stand gas ones.
Google "Ice auger portable drill adapters" and see how you can adapt your battery powered drill motors to use with your auger. Guys at one of our lakes used these last winter and they worked great. Winchester 88
