We have been working on this for a few years. There are many people that need to stay warm off the bike but with a limited power supply, we had to design the Base Layer to work with a 7.4 volt battery. We had to balance heat and time and weight. The greater the voltage, the greater the weight of the battery for the amps you need because as you increase voltage you increase the need for more amps. More amps, again, more weight. Then to get good heat with a battery that you can carry, you need to focus the heat. but then if you try to use more voltage, such as a car or motorcycle or a power supply off the main power, you get too much heat. We have solved that problem with our new Base Layer Heat-troller. With this new controller, you can run the base layer from 6.8 volts to 18 volts.
Ordering may seem complicated and may be I should have done this differently.
Choice 1: If the base layer is only for use at this time with a 12Volt to 18Volt power source, just select the Base Layer Size and that is it. This base layer comes with the Multi-Voltage Kit including the New Single Remote Heat-troller designed for Multi-Voltage, the 12Volt battery harness and the 12Volt Adapter Cable.
Choice 2: If you want you can also use this Base Layer with our 7.4Volt battery. Just select the battery you want. You get the 7.4V battery, charger, the extension cable, battery belt pouch and car power plug cable.
Choice 3: You can get an extra charger if you want.
Choice 4: You can order more batteries.
The base layer has 11 areas of heat. The chest, side of the chest, upper arms, neck, hands and lower back.
With our new remote heat-troller, it can take power from our 7.4volt battery or a 12volt source, from 6.8 volts to 18 volts with only a designed increase in watts.
