I have a battery (29.2v DC) and its made up of Lithium cells. Inside the battery there is a capacitor across the positive and negative wires which then lead directly out of the battery. The capacitor is a 35V 220uf.
Please can some one tell me what is the purpose of the capacitor in the battery? Also, would the presence of the capacitor positively effect the outcome of an EMC test on the device the battery powers. ( A brush less motor and controller)
