Castle Creations 8S CapPack 2240UF Capacitor Pack (35V)

The Castle Creations 8S CapPack 2240UF Capacitor Pack is a game-changer for high voltage brushless motor applications. With the ability to reduce ripple voltage, a common cause of ESC failure, this cap pack is an essential addition to any setup. It provides a much-needed boost to overcome ripples caused by aggressive acceleration or long battery wires, easing the load on the controller's capacitors. Equipped with four 560µF, 35V capacitors totaling 2240µF, its ripple-reducing capabilities are unparalleled. This versatile cap pack can accommodate LiPo batteries up to 8 cells, while those with batteries greater than 8s (35V) may opt for the 880µF, 50V CapPack. For even greater performance, multiple CapPacks of the same type and voltage can be installed as close to the ESC as possible. Invest in the Castle Creations 8S CapPack 2240UF Capacitor

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 exhibits more than 10% ripple voltage under peak loads, the user should consider using higher discharge (C Rating) batteries, shorter wires, higher current connectors, better gearing or a smaller load. 

NOTE: See Cap Pack installation guide in the resources tab above.

Applications:

• Surface Vehicles: With their high torque requirements – going from 0 to 100% throttle isn't easy on controllers or batteries - RC cars and trucks put enormous loads on brushless power systems. Use CC CapPacks in high performance applications (IE drag racing and high speed runs) to help your system power through the abuse. 
• Helis: CC CapPack is highly recommended for all 500 class and smaller heli applications where Y harnesses and long wires can bleed voltage, and hard collective pulls can strain even the most powerful batteries.
• Fixed Wing Aircraft: Larger electric power systems lead to larger electric 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 wire also adds inductance, which can increase the ripple voltage in a system. CC CapPack essentially negates the ripple caused by the addition of up to 12 inches of length to the battery wires.
