>>2027149I used mitts over my gloves before they do help but something about mitts just annoy me. I bought the largest ones I could find with removable liners so I could wear them over my normal gloves.
For both my gloves and boot heaters I put the batteries inside my jacket and run extension cables. I used some silicone adhesive to glue battery pockets into my jacket and cable guides down the arms and down the legs of my winter tights.
I used to have the batteries mounted on my boots but I switched to a different type of battery which wouldn't fit in the old holder or work with the old controller.
I'm using Aukey 10000mah USB-C batteries and some USB-C 9V boards from Aliexpress. Most heated stuff runs at 5V for USB or 7.4V for lipo batteries. The 9V board lets the heat pads run hotter than would at lower voltages. I added a PWM dimmer to control the output. A nice feature with the USB-C batteries is that pressing the button will switch between 5V and the alternative voltage the board I use can access giving me quick hi/low option. Pressing the button twice turns the battery off. The button is flush on the battery and almost impossible to press with gloves on, so I glued on the tip of a presta valve cap. This is how I made the controller and USB-C cable.
https://www.instructables.com/Heated-Clothing-Controller-and-Power-Options-Versi/I got the new gloves sealed up. They get very warm on the palm at 9V. Though they won't get as hot when I'm running both at the same time since the battery limits the output current. I'll use the dimmer to dial back the output to a good high setting. After flipping them right side out the heat pads don't quite reach the finger tips but that shouldn't be a problem.
I can usually get over 2 hours out of the batteries. I switch between high and low as needed for the boot heaters.
