Energy efficiency!
CC CapPack is useful in all brushless motor applications where it serves to provide just that little boost needed to overcome ripples in battery voltage caused by heavy acceleration or long battery cables. Ripple voltage is hard on an ESC - adding the CC CapPack can help reduce the load on the controller's integrated capacitors. This CapPack uses three 560-µF, 35-V capacitors totaling 1680 µF, which increases its ripple reduction capabilities. It can be...

Energy efficiency!
CC CapPack is useful in all brushless motor applications where it serves to provide just that little boost needed to overcome ripples in battery voltage caused by heavy acceleration or long battery cables. Ripple voltage is hard on an ESC - adding the CC CapPack can help reduce the load on the controller's integrated capacitors. This CapPack uses three 560-µF, 35-V capacitors totaling 1680 µF, which increases its ripple reduction capabilities. It can be used with LiPo batteries up to 8 cells. If your batteries are longer than 8 s (35 V), you will need the 880 µF, 50 V CapPack .
Helis:
CC CapPack is strongly recommended for all helicopter applications of class 500 and smaller, where Y-harnesses and long cables can dissipate voltage and hard collective pulls can stress even the strongest batteries.
Surface Vehicles:
With their high torque requirements - going from 0 to 100% throttle is not easy for controllers or batteries - RC cars and trucks put tremendous stress on brushless drive systems. Use CC CapPacks in high-performance applications (e.g. drag racing and high-speed running) to help your system survive the abuse.
Fixed-wing aircraft:
Larger electrical power systems lead to larger electrically powered aircraft, and sometimes the distance between the battery pack and the ESC grows beyond the length of the wires installed on the components. Adding wires also adds inductance, which can increase the ripple voltage in a system. CC CapPack essentially negates the ripple caused by adding up to 12 inches of length to the battery cables
Reference:
All Castle controllers with data logging capabilities can report the ripple voltage they encounter during use. Ripple voltage peaks should always be less than 10% of the total pack voltage; the smaller the ripple voltage, the better. If an application experiences more than 10% ripple voltage under peak loads, the user should consider using higher discharge (C-rated) batteries, shorter wires, higher current connectors, better equipment, or a smaller load.
Multiple CapPacks may be used in an application. They should all be installed as close to the ESC as possible.
