I have had good luck with internal-battery-powered gloves. They do a good job of keeping my hands warm on a short ride, but mine only last for about a hour on the highest setting before needing to be recharged. There are a ton of heated gloves for sale on Amazon. Cheap ones for hiking, skiing and snowmobile riding and expensive ones for motorcycle usage.
Heated gloves powered via a 12V system off of an outlet on the bike should work just fine if you don't mind the wiring flapping around a bit.
I also own both, the battery heated gloves and the ones that need a 12V connection to the bike. I normally use the battery ones and I take spare charged batteries with me. Mine are the SnowDeer motorcycle gloves. I cannot get an hour on the highest settings, perhaps a half hour. But that will get me over the summit where it is the coldest. It is really cold up that way now. A couple of days ago, I rode east on Highway 20 to Cisco Grove. It was VERY cold on my Experia. I used both, the heated grips as well as the gloves on the highest settings. Lots of snow on the ground and possible ice on the roads in some shady areas. I had to be extra careful and slow to avoid the wetter areas.
I wanted to check to see if I could use the CCS Chargepoints at Cisco Grove. But I couldn't get to them. They are buried in the snow! So I came back in I-80, tried the CCS ChargePoint in Colfax. It did NOT work. And it's the same type of charger at Cisco Grove so I assume it runs the same FW. But I used the ChargePoint J-1772 there and then had lunch. Cisco Grove also has a J-1772.
Today, I rode my Experia 161 miles. I first went to Forest Hill, then to Georgetown. Then to Plymouth and then back home via Folsom Lake. I did slow AC charge a few minutes in Georgetown and Plymouth (while I had lunch). Both were free charge stations. I put my bike on Plugshare.
