[Sleeves] Description One of the best ways to seal your battery is by using heat shrink. It can protect your battery from short circuits, seal your battery against the weather and add a professional look to your DIY battery. PVC heat shrink is great for battery use, but it can sometimes become brittle over time and begin to crack at the edges or at sharp corners. One method around this is to use multiple layers. This strengthens the heat shrink and adds a second line of defense if one layer should begin to crack. It also allows you to use multiple pieces of heat shrink perpendicular to each other to cover all six sides of a battery instead of just four sides, thus completely sealing your battery. Adding a thin layer of foam around your battery can also help prevent cracking of the heat shrink over time. 210mm PVC Heat Shrink Sleeve For Battery Pack Colour- Blue Radial Shrinkage- 9% – 21% Depending on the Size Material- Poly Vinyl Chloride Tensile Strength- Greater-than or Equal 4000 Pa/m2 Package Includes : 1 x 210mm PVC Heat Shrink Sleeve Blue for Lithium Cell Pack (1 Meter)
