How do I shrink a pack of Li-ion batteries without damaging them?

How would I apply the necessary temperature to shrink PVC heat shrink-tubing (80℃) to a pack of Li-ion batteries without damaging them? Apply the heat quickly and be done with it. The way I see it, use a hot gun. The tube will shrink quickly until it touches the battery and then it will stop shrinking because the tube is cool.

Can You Heat a Li-ion battery with a heatshrink?

Do not keep heating the tubing after it touches the battery all the way around. Which Li-ion batteries? The batteries have a higher specific heat capacity than the heatshrink and the heatshrink should shield the hot air from the PCB while it is not tight.

How do I install a shrink-wrapped battery pack?

Place in Hard or Soft Case: Install the shrink-wrapped battery pack into a hard case or a soft protective case, depending on your specific needs. Secure the Case: Ensure the case is well-ventilated for heat dissipation, especially if the battery pack is in use for extended periods.

How do I stop a battery from shrinking?

Apply the heat quickly and be done with it. The way I see it, use a hot gun. The tube will shrink quickly until it touches the battery and then it will stop shrinking because the tube is cool. You want to apply the necessary amount of energy as quickly as possible.

How do you calculate a heat shrinkable sleeve?

The calculation formula is: cell height * cell number + cell width. For example, this time the cell size is 145 * 49 * 8mm, and the required width of the heat shrinkable sleeve is: 8 * 4 + 49 = 81mm. The width of the heat-shrinkable film must be greater than 81mm.

How wide should a heat shrinkable film be?

The width of the heat-shrinkable film must be greater than 81mm. In view of the shrinkage characteristics of the heat-shrinkable film, there must be some room for selection. we chose a 90mm wide heat shrinkable film this time.
