Lipo Battery Wrap-Rewraping, HEAT Shrink And Necessity

Aug 13, 2020   Pageview:74

Lithium Polymer Batteries or LiPo Batteries are light weighted, flat, robust, and long-lasting batteries that stand out from other lithium batteries available in the market. These batteries are widely used in electronic devices nowadays. But these are various risks that are associated with its usage. Therefore these batteries need to be carefully handled by the end-user, and sometimes they need to be rewrapped also. So under this article, you will get to know everything related to wrapping your LiPo Batteries.

Do you rewrap LiPo with shrink wrap 

LiPo batteries are exposed to various risks; therefore, they need to protect to avoid those risks. For preserving these batteries, you need to keep the LiPo batteries in a protective case. When the Stock wrap of the LiPo battery gets damaged, scratched, or ripped, you need to rewrap it to avoid dangers.

There are various methods of rewrapping the damaged LiPo batteries, but amongst all of those methods, shrink wrapping or heat shrink wrapping is the most comfortable and quick method to apply. Shrink-wrapping Lithium Polymer Batteries with heat shrink tubing will protect the LiPo battery from physical damage and also increase its cycle life.

While rewrapping or shrink wrapping the LiPo Battery, you can either remove the original packaging, or you can keep it as an extra protective layer. For safety purposes, avoid using lighters or any kind of fire because it will be a bad idea to use flames or fire to melt the shrink wrap.

So, the answer to the question mentioned above is "YES," and rewrapping the battery with shrink wrap involves removing the old wrap and wrapping the battery with new shrink wrap with the help of a heat gun until the wrap gets tightly and firmly fitted all over the LiPo battery.

How do you heat shrink your LiPo battery 

Heat shrinking is one of the best and trusted ways to seal and rewrap the Lithium Polymer Batteries. It can protect your LiPo battery from short circuits, puncturing, external damage, etc. Various LiPo heat shrink tubings are available in the market and online that will help you to heat shrink the Lithium Polymer Batteries.

Here is a quick guide in just three simple steps about how to heat shrink your LiPo Battery.

Step no. 1: Choosing the Heat Shrink

The first step in heat shrinking a LiPo battery is to choose an appropriate heat shrink tubing for wrapping it. There are various types of heat shrink tubings available in the market, but you need to select the heat shrink tubing suitable for your LiPo battery.

These heat shrinks are not only available in different colors, but they are also available in different materials. Among all of them, PVC heat shrink is excellent for battery use.

Step no. 2: Selecting the Right Size of Heat Shrink

The second step is to determine the size of the heat shrink that you will need. Measure the perimeter of your LiPo Battery. Then add the height and width of your battery to get a number and multiply that number by 2 to get a new number. You need a size of heat shrink between these two numbers.

Step no. 3: Installing the Heat Shrink

Before heat shrinking a LiPo battery, make sure that you have tested your battery because it will not be that easy to open the heat shrink if you forgot something.

Now while making sure that the wires are out of the way, slide a piece of heat shrink tubing around the LiPo Battery. Do remember that the piece should be long enough to cover each side of the battery. Now start adding heat to it from a heat gun set on "High" mode so that it can melt the heat shrink quickly. Start this process on the ends of the battery until it wraps around the whole of your LiPo Battery.

And that's all you need to do!

What is the necessity of LiPo battery wrap 

The Lithium Polymer Batteries or LiPo batteries must be handled carefully and securely to avoid any sort of physical damage to it. Otherwise, it may explode and cause fire risks. The sensitive chemistry of the LiPo Battery can lead to a fire if the battery gets punctured. Therefore you need to rewrap and seal your lithium polymer batteries.

The plastic which is wrapped around the LiPo Battery protects it from metal on metal contact, which is essential for your safety. Therefore using LiPo batteries without wrap are dangerous to apply; otherwise, it could be short circuits and potentially caught on fire or explode.

As you have read that unwrapped Lithium Polymer Batteries are associated with so many risks and dangers, therefore there arises the necessity and need for wrapping these batteries. On the other hand, if you notice any kind of rips or tears on the LiPo battery's wrapping, then you need to either replace the battery or rewrap it to avoid any danger.

There are two signs that you must notice to find out when your LiPo battery needs to be re-wrapped.

 The stock wrap has been scratched, ripped nicked or dinged.

 The stock wrap has become discolored.

Hence, you need to wrap or seal your Lithium Polymer Batteries to avoid fire, short circuits, and explosions.

Conclusion

This was all about wrapping necessity, hot shrink wrap, and rewrapping a Lithium Polymer Batteries. Since these batteries without proper wrapping can be dangerous to use. Therefore you must wrap them in order to avoid short circuits and explosion. There are various LiPo battery heat shrink tubing available in the market that you can use to shrink wrap your LiPo batteries. Try not to over complicate the process of rewrapping. Just go through the heat shrink wrapping guide above to get a better clarity into the situation.
