Figure 4: Correctly installing a CAP-XX cylindrical cell supercapacitor
When using only one single CAP-XX cylindrical supercapacitor, the empty cylindrical slot must be
shorted with a wire link from the positive to the negative terminal. Also, the active-balance

should be fitted with their correct positive and negative terminals and the active-balance
configuration header must be connected to the cell midpoint as shown in red on the right of figure
5.
