the capacity cabinet, which has a cavity for placing multiple batteries and opening multiple batteries; 

Multiple positioning components in the cavity body are used to locate the battery; multiple fast clamps,

 the end of the ends of the telescopic rod is set for fixing boards for fixing positive heat dissipation 

probes and negative heat dissipation probes; It is used to drive positive heat dissipation probes 

and negative heat dissipation probes at the same time or downward; and the positive heat dissipation 

probe and negative heat dissipation probe fixed on the fixed board. The positive heat dissipation probe

 and the negative heat dissipation probe are in contact with the positive and negative columns of the battery, 

respectively, and the attery test testing the battery, which significantly improves the efficiency of the capacity test test.
