Plastic housing 1x2 thanks to which you can bundle Li-Ion 18650 batteries. Assembly is quick and very easy. The housing holds the cells together so that the subsequent welding process is much easier, and the housings themselves have small grooves for the plates so that they will not stick out.
Thanks to the housing there is space between the cells, so that one cell does not heat up from the other, and in addition it will be possible after placing the package in the housing to effectively ventilate / cool it with air.
The housing has tabs and grooves for them on each side through which they can be combined as desired.
