NOTE: 16v batteries do not fit inside the pocket and must be used with the stickman wire.The fast charger cannot be used with the 12v 0.9Ah small batteries.
we first started looking into the heated gloves, we found there were 2
types. Liners and gloves. All the liners we looked at ran 8 volts at
most, so the highest temperature we got from them was a measly 35°C for a
very short duration. So while they had nice, slim and light features,
the liners didn't the punch to get us through the -30°C to -40°C
weather we get from time to time in Canada. Nor did they last us very
long on the high settings which we only found to be warm.
12v gloves we looked at were very warm, but were very bulky heavy
gloves and expensive. They were designed for motorcycles and snowmobiles
so finger mobility wasn't a huge concern for them. Since we wanted a
glove for cyclists, we need our fingers to be nimble to hit our
shifters, brakes and hold onto the bike at the same time.
we decided to take our product development skills from electric bike
components and apply it to make a 12v glove liner for cyclists. The
liners offered the advantage of being able to use multiple different
gloves over top of the liner. We wanted 12v because it packed the punch
we needed to get through the cold weather.
decided to stick with the 12volt battery for a couple of reasons. At a
lower voltage, the gloves simply can't very warm. So while it is easy
drop the voltage down so the battery can be smaller, it means you get a
glove that performs very poorly in cold weather. 12 volts is also the
common battery voltage for most automotive vehicles so our gloves with
the right connection can also be hooked up to your car or motorcycle.
we first started with the gloves, we were making it to extend the
cycling time for a electric bike, so we wanted to be able to hook up our
gloves to the electric bike's battery. We also noticed from our testing
of the motorcycle heated gloves that the battery weight was very
noticeable if you needed to use your arms a lot. Moving the weight of
the batteries from the wrist to a more comfortable chest pocket just
seemed to be the practical thing to do. We've since added a cuff to the
gloves that allows you to run which ever method you prefer.
reason we've gone with woven carbon fiber as the heating element is
that it is very thin and flexible. In our Youtube video on the evolution
of the MOTIONHeat glove liners, there is a shot of the carbon fiber
heating element used in our gloves. Carbon fiber pretty much resembles
hair, but heats up very quickly when a current is applied through it.
Yes, we were just as surprised as you when we found out how this little
bit of carbon fiber could provide heat without us feeling much of any
wires while wearing the gloves.
