For me, if I'm riding below 25 degrees (F), I use my heated gloves liners. I recommend the Power In Motion ones. They run at 12v and generate a lot more heat than the ones that run at 7.4v. I have the glove liners in combination with bar mitts. I usually kept it running in medium heat if I'm riding for a few hours. You can run it on high, but you'll get so hot you'll have to pull them out of the mitts to cool down. Most heated jackets run at 12v and the gloves come with cables to join everything.
