Please note
Calculation method for the size of commonly used cylindrical and square battery sleeves
Sleeve diameter: generally referred to as the flattened width, which is one and a half of the circumference. So before buying, you must first calculate
The circumference of the product is calculated by dividing it by 2 to obtain the required sleeve width, usually 5 to 10 millimeters larger for convenience
Install the battery, and the shrinkage rate of the heat shrink tube is about 48%. It doesn't matter if you buy a larger one, but if you buy a smaller one, you won't be able to use it.
The circumference of the cylinder=diameter x3.14,
For example, if the diameter of a cylinder is 20mm, the circumference is 20x3.14=62.8mm
Circumference of Rectangular cuboid=(length+width) x2,
For example, the perimeter of Rectangular cuboid section 1 is: (95+25) x2=240mm,
The perimeter of section 2 is: (45+25) x2=140mm
