The idea of using a battery pack on a motorcycle has real limitations. Heated clothing uses a lot of power and battery packs are capable of generating only a fraction of that power requirement and for very limited periods of time. For example, Warm n Safe is pretty blunt about it. They have developed a battery pack that is capable of powering the 90 watt Heated Liner powered with the 7.4 volt battery will produce 30 watts of heat when turned on full power, but for only one-hour at a time before recharging. It is a simple function that heat generation and time of use are limited by physical constraints like the size and weight of battery packs. I will be very surprised if battery powered clothing is satisfactory for anything but short periods of time providing minimal supplemental heat.
10 hours? the Ansai li-ion battery is 7.42V 2.2ah That means for 10-hours you can produce at-most 0.22 amps at 7.42 volts. That yields only 1.63 watts of heat, or more like 16.4 watts of heat for one-hour. That is about 1/2 of the heat output calculated by WNS here. based on a 7.4 VDC 5.2 ah battery. It's a great idea, but the claims of heating clothing for 10-hours are unrealistic, and even if theoretically possible to meter heat from such a limited battery over that period of time, would not generate perceptible heat.
