AddCAP 820, AddCAP 1640
1. Description
AddCAP 820 and AddCAP 1640 are add-on capacitor units designed to enhance battery power supply for drive
systems using low-impedence electric motors (1-2 pole). They should also be used when the wires from your battery
to your ESC need to be lengthened more than 20cm (8 inches). In cases where the wires are longer, use one AddCAP
820 or AddCAP 1640 for each 20cm (8 inch) 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.

3. Installation procedure
1. Prepare the cables and tin (pre-solder) their ends.
2. Put the large piece of heat shrink tubing over the power wires. It will be slipped over the capacitor once
the power wires have been installed. Be sure to keep this tubing far enough away from the unit while you
are working so that it does not get shrunk when soldering the power cables.
3.
Put the small shrink tubing over the cables at the wire support tabs (match the colors, see picture 1),
align the ends of the cables on the prepared solder pads as shown (cable ends should be as close to each
other as possible), then shrink the cables to the support tabs on the PCB using a heat gun.
4.
Carefully solder the cables (see picture 2).
5.
Put the large piece of heat shrink tubing over the capacitor. Shrink it with a heat gun and apply the
sticker (see picture 3).
