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 the 7.4 volt battery. Limited to 5.4 amps, we had to balance heat and time and weight. The greater the voltage, the greater the weight 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 a power supply off the main power, you get too much heat. We have solved that problem with our new Base Layer Heat-troller.
Ordering may seem complicated and may be I should have done this differently.
Choice 1 is the base layer only for those who already have purchased before.
Just select the Size and that is it.
Choice 2 is the base layer for use only on 7.4V to 9V.
You select the base layer size, then the battery. With it you get a 7.4V controller, an extension cable to go from the base layer to the battery, battery charger and a battery belt pouch.
Choice 3 is the base layer for use with all voltages between 6.8 and 18V.
You select the base layer size, then the battery but from the second battery group, and the base layer 12V kit. You get the New Single Remote Heat-troller, 7.4V 5.4amp battery, charger, the extension cable and Battery Belt Pouch. The Optional 12V kit includes the following: 12V Battery Harness, 12V adapter cable, car power plug cable.
You can order more batteries.
if this is too complicated, let me know
The base layer has 7 areas of heat. The chest, upper arms, neck, upper back and lower back.
Has connections at the end of the sleeves for gloves or glove liners that will be coming out.
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.
