AddCAP 820 and AddCAP 1640 are add-on capacitor units designed to enhance battery power supply for drive systems using low-impedance electric motors (1-2 pole), mostly Electric Ducted Fan or Geared Inrunner motors. They should also be used when the wires from your battery to your ESC need to be lengthened more than 200mm (8″). In cases where the wires are longer, use one AddCAP 820 or AddCAP 1640 for each 200mm (8″) section. Another advantage of adding an additional capacitor is to reduce possible interference which may be caused by current moving through your power wires. Recommended for use with 2.5-6 mm2 (14AWG – 10AWG) wires.
