Z-Folding Process

The Z-Folding process delivers a superior performance advantage, leveraging its low internal resistance to enable efficient high-current discharge and a 0.2V higher voltage under load compared to wound cells, ensuring consistent and robust power. This architecture also achieves a 5% higher energy density within the same volume and a significantly extended cycle life. Furthermore, it provides unparalleled design freedom, allowing for precise customization of the battery's size and shape to meet specific application requirements, offering broader versatility than traditional winding methods.

Warning

  • Please fully charge the new battery before use.
  • Only use a charger designed for lithium polymer/Li-ion battery, and never leave the battery unattended during the charging process.
  • Always keep the battery away from flammable and explosive materials while charging.
  • Never overcharge the battery. The maximum voltage for a LiPo battery is 4.2V per cell, and for a LiHV battery is 4.35V per cell.
  • Never discharge the battery to a level below 3V per cell under load.
  • Do not store fully charged batteries for more than 3 days. For long-term storage, maintain the voltage between 3.8V and 3.9V.
  • Do not disassemble, crush, short circuit, or expose to flame or other sources of ignition.
  • Do not use batteries that are deformed or swollen.

Durable, Odorless, and Reliable — A Must‑Have 3‑Pack
Size: 3Pack 16"x20" Black
I’m really impressed with this 3 Pack PTFE Teflon Sheet for Heat Press (16 x 20"). The quality is excellent, and the non‑stick surface makes every press come out clean and smooth. One thing I really appreciate is that there’s absolutely no smell, even when using high heat. It makes the whole process more comfortable and professional. These sheets offer great protection for both the heat press and the materials. They prevent scorching, keep the plates clean, and stop any vinyl or ink from sticking. My projects come out more consistent because the sheets help distribute heat evenly and act as a reliable barrier. The 3‑pack is a huge bonus. I keep one on my press, one as a backup, and one for different materials like HTV or sublimation. It saves time and keeps everything cleaner when I’m working on multiple items. The 16 x 20 size is perfect for shirts, tote bags, and larger designs, and the sheets stay flat without curling. If you want something that protects your equipment, has no smell, and delivers clean results every time, this set is definitely worth it.

T shirt Quilt Use
Size: 3Pack 16"x20" Black
I bought this specifically for ironing interfacing onto t-shirts before cutting into squares. Some of the memory t-shirt's had ‘puffy paint’ and other shirts had uncertain designs that may be ruined by ironing without protection or by using just a pressing cloth (cotton material). A teflon sheet was suggested on a you tube video to ‘play it safe’ when making a memory quilt. I felt the heat resistance teflon helped because you need to hold iron in same place for a longer time than ‘regular ironing’ movement. It worked well, the only (minor) issue is you can’t see through it. It did not interfere at all because positioning of shirt and interfacing was in place. I’m a ‘newby’ at this process; this worked for me. This is a good quality material; one sheet can be used for ironing t-shirts forever, I plan on using the other two teflon sheets to line outdoor BBQ drawer.

High Quality & a Must-Have for Any Heat Press User
Size: 10Pack 12"x16" Black
These PTFE sheets are an absolute must if you use a heat press. I use them all the time and the quality is excellent. They’re thick, durable, and truly non-stick, which makes pressing vinyl so much easier and cleaner. They protect my projects and my heat press perfectly, and they hold up well even with frequent use. I also love the size—plenty of coverage for different projects. This 10-pack is a great value for the price, especially if you’re pressing often like I am. I’ll definitely be keeping these on hand and repurchasing when needed.
