<p>I was looking at the Ebay battery for a grip that is 7.4 volts and 4200Mah that works in a D7000 grip. It's a much bigger battery with slightly higher voltage (a concern?) but would appear to have huge capacity. Has anyone tried this battery? </p> <p>Seems that I can't link to an Ebay auction so the auction title is "<strong>DSTE 7.4V 4200mAh EN-EL15A battery for Nikon D7000 Battery Girp MBD11 MB-D11</strong>" (no I didn't misspell "Grip")<br> There appear to be plenty of them selling on Ebay. Thoughts?</p>
