Discussion on 18650 battery pack heat shrink

18650 battery pack is one of the most commonly utilized items by lots of people. There is a great amount of population that utilizes this item to carry batteries from one place to another.

As we all know that lithium-ion batteries can catch fire in some situations. It is quite possible that when the battery catches the fire, it burns everything that is near to it. In this case, these batteries are kept in some safe environment where there are quite low chances of such happenings.

So, here we are going to tell you about some of the aspects of the 18650 battery pack that you should have to be known before their usages.

Choosing Best Heat Shrink

There is a wide range of heat shrinks accessible in the market, but in general terms, people usually search for enormous diameter across heat shrink. This will be huge enough to accommodate the batteries. There are likewise various styles of heat shrink. In addition to the fact that it comes in various hues, yet various materials are accessible also. Most huge width heat shrinks are a genuinely thin PVC heat shrink.

PVC heat shrink is extraordinary for battery use, however, it can become weak after some time and start to split at the edges or at sharp corners. One strategy around this is to utilize various layers. This reinforces the heat shrink and includes a second line of safeguard in the event that one layer should start to break. It additionally enables you to utilize numerous bits of heat shrink opposite to one another to cover each of the six sides of a battery rather than only four sides, in this manner totally fixing your battery. Including a slim layer of froth around your battery can likewise help anticipate splitting of the heat shrink after some time. Thicker elastic style heat shrink is additionally accessible. This heat shrink can, for the most part, confront more maltreatment, but on the other hand, is increasingly costly in the enormous sizes required for battery use.

Size of heat shrink

This is quite a normal question to ask related battery building. It's very easy to decide, particularly for square shapes. Initially, you need to comprehend the measures of heat shrink. Dissimilar to little heat shrink for wires that are estimated by the distance across, huge size heat shrink is normally estimated by the leveled width rather than the breadth. This is on the grounds that it comes level on a roll and this strategy for estimation is simpler. The level is likewise 50% of the circuit of the hover framed by the heat shrink when it is opened.

You can also figure out the size heat shrink you need. First of all, you have to calculate the border of your battery. With the 4 inches thick and 5-inch wide battery underneath, you essentially gather the tallness and width into a single unit to get 9 inches, which is additionally a large portion of the edge of your battery. Since most heat shrink has a shrink proportion of 2:1, you need a bit of heat shrink with a half boundary size of at any rate 9 inches. Be that as it may, you likewise need to ensure that the heat shrink is not as much as double the size of the battery, which means it can't have a half circuit size of more than 18. That implies you need a bit of heat shrink that is between 9-18 inches. Ideally, you will pick a piece that is more like 9 inches with the goal that it presses more tightly on the battery.

On the off chance that it sounds confounded, at that point here's the simpler way. Include the stature and width of your battery to get a number. At that point duplicate that number by 2. You should have the heat shrink size that is between those two numbers.

Why does the 18650 battery pack have heat shrink?

As you know that most of the batteries, especially lithium-ion batteries get into some kind of chemical reaction which causes fire into the battery. If you are not familiar with the fact then you should be aware of it that most of the batteries can be dangerous if they catch fire and can burn everything that comes in contact with the fire. This is the reason that the 18650 battery pack must have the heat shrink so that it can protect the battery from external abnormal situations and also keep the nearby things safe from the fire if battery catches it in any case.

Effect of 18650 battery pack heat shrink

The usage of heat shrink is above-described that it protects both battery and the substance near to it if the battery gets fire. Additionally, you should also be aware of the facts that in what effects heat shrink offers to the battery and battery pack.

First of all, it protects both battery and the substances near to it. Secondly, it prevents the external heat to affect the battery and become the cause of appearing fire in it. It also prevents the wet to get in contact with the battery which can affect its performance and make it useless. In short, all the things that can affect the battery in negative ways, are presented with the help of this battery pack heat shrink.

How to avoid 18650 battery pack heat shrink

Well, it is quite genuine that battery pack heat shrink protects the battery in an incredible way and it resists all the warm and wet materials to affect the battery but still, it is important that the battery pack heat shrink should not get much exposure to such things. You should also avoid placing your battery or battery pack heat shrink at such places where the temperature is too much high or any liquid near it. These things can keep the strength of heat shrink stable and make it resistant from all such situations.

So, consider all the above-described aspects and make sure to keep your batteries safe.
