Picture of DIY carbon tape heated vest
diy heated clothing kit

The pattern made from some factory vest.
6 meters of carbon heating flex tape ( placed on back and both sides. By touch carbon is a little bit like a loose weave silk. It's very soft but strong enough.
Because of big length it provides uniform heating of body.

Step 3:

Picture of
Tape connected in parallel 6x1m. It takes about 3A under 12V (36W).

Step 4:

Picture of
You can sew wire to carbon tape to make a good and flexible connection.  The contact place shouldn't be hotter than the tape itself. If not you must increase the contact area. The best idea to place wire between two layers of carbon tape.

Step 5:

Picture of
Contacts may be sewed by sewing machine or just wraped with a wire.
But as you can see sewed contact is colder than the tape itself (left contact).
Wraped contact (on the right) is more hotter than tape.

Step 6:

Picture of
Carbon tape can be extended.
Place two pieces of carbon tape together on each other with little overlap and sew it on.
As you can see the connection place is not hotter than the tape itself.

Step 7:

Picture of
Sewed contact very flexible.

Step 8:

Picture of
It's powered by 6x18650 connected in parallel (2x3).
I use it with an adjustable controller.

Step 9:

Picture of
With a half power. I use it with my heated gloves and insoles.

I like this. Have you tried snap buttons instead? That way you can disconnect the connections.
Shenzhen (author)  NWBrewer1 year ago
You can see the battery connector and a power button the same as placed inside right there.
Can you wash it?
Shenzhen (author)  NWBrewer1 year ago
Yes, I can wash it without any problem.

Created a terminal end for joining 22ga wire to the carbon tape... and this happened [see pic]. I have a series of 4 carbon strips ~10" in length and this was the 2nd strip... Has this happened to anyone else? Or how do you prevent this from happening?

Shenzhen (author)  ToddM21 month ago

To answer your question you need to know:
1. Voltage, current
2. Photo the other side of your contact.

Could you provide, please.

ToddM2 Shenzhen1 month ago

We're running 12V - 1.5A

Shenzhen (author)  ToddM21 month ago

We need to see how the wire placed on the carbon but it closed with that red fabric. Could you open it?

hairyogre3 months ago

excellent project...what width tape are you using here?

Shenzhen (author)  hairyogre3 months ago

15 mm.

Hi Shenzen, received tape yesterday and made a similar jacket to this one. I am now nice and warm thanks to you. I will be buying some 44mm to try out in the New year. Really excellent project and it really works fantastically well. Best project on this site. Well done, you are my Hero!!!

Shenzhen (author)  hairyogre3 months ago

Thank you for the good information.

Now you could make some instructables about, get "Popular", and we send you 10 meters of carbon tape for free! Every one can be a Hero, just do it!

can a 3s 2200mah lipo pack be used as power source and do i need a protective circuit? (due to the nature of the lipo packs, they are tend to burn or bubble)

Shenzhen (author)  Bülentİ4 months ago

That pack has about 20-25 Watt of power. It's not much but of course you can use it.

Protective is very usefull and recommemded.

Do you have a sketch of the electrical connections on the vest, I am not clear as to how this is wired, it appears that the wiring is connected in multiple spots on one continuous ribbon....
Shenzhen (author)  Navy_Chief1 year ago
The tape is divided into 6 equal parts1 meter of each. Parts are wired  to obtain 6 parts in  parallel. The first figure below shows the wiring on the vest. The second figure shows the equivalent circuit.

2 questions on this. In step 7, the positive and negative connections appear to be in the same location at the top of the vest. Are the connections isolated from each other right there? Also, the 6 - 1 meter sections... Are they separated, or is it a continuous strip with power connections in the middle? Thank you.
Shenzhen (author)  locozap4 months ago

Yes, it's a continuous strip with power connections in the middle.

It is just one connect with two wires. Sorry about different colors.

This looks awesome. I have a quick question about safety:

How do you insulate the tape?

Can you touch the tape when power is connected?

Shenzhen (author)  mnørgaard4 months ago

Yes, you can touch it when powered because of low temperature and voltage.

I insulate it with a thick fabric only.

What makes this carbon fiber tape resistant? Is it different than other carbon fiber fabrics I can find? The one I tried from the local shop barely generated heat.

I was thinking about making some glove liners and using the removable liner in my riding jacket for this project. But I'd like to know if I connect the gloves at the sleeves of the jacket and have power coming into the bottom of the jacket from the motorcycle if it would work. Or should I have a separate power source for the gloves? And lastly, is the 12 volt power for the bike to much power?

Shenzhen (author)  paul.barber.904754 months ago

Yes, the 12 volt power supply is very convenient for gloves. Separate connection is not required. Connect gloves to sleeves. I think that will be enough 10 watts for each glove, it is not much of power for a bike battery.

Shenzhen Hi, tell me what you used to do the tire warmer to motorcycle tires, carbon fiber, the same material or something else? I need 80 degrees

Shenzhen (author)  adam.walicht5 months ago

Dear Adam,

Yes, the same.

Carbon tape better than other heaters if needed flexibility, resistance to repeated bending, uniform heating of a large area. So it's also used in a good quality steer weel heated covers.

Thank you for a fresh idea. We offer you a discount of 20% for you first order on

Do you have a special circuit or recommendation for charging the battery pack?
Shenzhen (author)  elubbers5 months ago

This one:

leviwilner1 year ago

Wow this is great!!

How much power will I need to keep water from freezing in a hose? the fabric dimensions would be 88.9cm x 35mm. I want the battery to be as light as possible also

Shenzhen (author)  leviwilner1 year ago
1. Water temperature?
2. Pipe diameter?
3. Water speed?
4. Air temperature?
5. Air speed?
6. Is it possible to cover carbon tape with some insulation?

1. ~4.4C

2. 6mm inside diameter

3. same as drinking though a straw

4. ~ -7C

5. 0

6. yes there would be insulation over the tape.

Shenzhen (author)  leviwilner1 year ago

Depend on insulation quality and thickness it will be enouph one piece of 90 cm 44 mm carbon tape at 3,7v.

I just received that material (from you?) I ordered online and it came from Russia. I am ready for try things. Would you, please, show the calculations for this example (90cmx44mm @ 3.7v)? Thanks

Shenzhen (author)  macinissa.mezache5 months ago

It's about 8 Ohm/m, so for 90cm it's 7,2 Ohm.

3,7v : 7,2Ohm =~0,5Amper

The temperature depends on current only. I've made a table current/temperature. As you can see it starts from 0,92Amper (39,3 Celsius). I think at 0,5A you'll get less than 30 Celsius. To increase the temperature you should increase the voltage or decrease the tape length.


Great Thanks!

MrJack20015 months ago

Are you able to cut the tape down the center of the width making thiner tape?

Shenzhen (author)  MrJack20015 months ago


Shenzhen (author) 6 months ago

how fast does this warm up and to what temperature? more specifically how fast does a 12" length of the carbon tape heat up?
