16V10000F super capacitor bank

Short Description:

A capacitor bank consists of many single capacitors in series . For technology reason, unipolar rated working voltage of the supercapacitor generally at about 2.8 V, so in most cases must be used in series, since series connection circuit of every single capacity is difficult to guarantee 100% the same, it is hard to ensure that each monomer leakage is the same, this will result in a series circuit of each monomer charging voltage, may cause the damage of capacitor over voltage, therefore, our super capacitor in series are additional equalizing circuit, ensure each monomer voltage balance.
