I'm buying a Hohm slice for my wife and know nothing about 26650 batteries. I looked at Mooch's tests but liionwholesale.com only has one of the batteries he suggests in stock. That I saw anyway and that was an Efest battery. All I've ever heard is they are bad bad bad. Is this a good battery in the 26650 and not in the 18650? Just wanna make sure before I order some. Thanks!!
