Here is our 12 Volt DC, 5200mAh rechargeable lithium-ion battery kit with a pair of heated insoles and a "Y" wire for the connection between the battery and the insoles. The battery has a built-in controller with 4 intensity levels. The soles can be cut to size. 

Plug the "Y" wire directly into one of the 2 battery outlets. You should put the heated soles in your boots, your feet with your stockings directly on them. Plug the soles into the appropriate connections. To turn on, press the red battery button for 2 seconds, a red LED will indicate that the battery is working at maximum. Press the red button again to change the intensity to obtain the best possible comfort.  

Tips

• The battery is capable of delivering a maximum of 36 Watts. So, for a pair of insoles, you will have up to 30 hours of battery life (at 25% intensity or flashing green).
• If you connect 2 devices on battery, they will be at the same level of intensity.
• The battery has no memory effect. You can therefore recharge it every evening, if you wish.
• Weight: 320g or 0.7 lbs
• For best battery life, we recommend that you wear the battery as close to your body as possible. You can put it in an inside pocket of your coat or with it you can use our battery case and wear it on your belt.
• Before storage, we recommend that you recharge it. If the period is prolonged, we recommend that you recharge it every 3 months.
• The yellow side of the soles is anti-slip.
