The CC CapPack is useful in all brushless motor applications, where it serves to give just that little boost needed to overcome ripples in the battery voltage caused by hard acceleration or long battery wires. Ripple voltage is hard on an ESC — adding the CC CapPack can help reduce the load on the controller's on-board capacitors.

CC CapPack is highly recommended for all 500 class and larger heli applications where Y harnesses and long wires can bleed voltage, and hard collective pulls can strain even the most powerful batteries.

With their high torque requirements, RC cars and trucks put enormous loads on brushless power systems. Use CC CapPack to help your system power through the abuse.

For larger electric power systems and aircraft where the distance between the battery pack and ESC grows, adding wire also adds inductance which can increase ripple voltage. CC CapPack essentially negates the ripple caused by the addition of up to 8 inches of length to the battery wires.

880µF Capacitor Pack

The CC CapPack uses four 220µF, 50V capacitors totalling 880µF and is recommended for all 500 class and larger heli applications.

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. Multiple CapPacks may be used in an application. They should all be installed as close to the ESC as possible.
