This is the Castle Creations CC Cap Pack - Capacitor Pack. The Castle Creations CC CapPack is useful in all brushless motor applications. It serves to give that little boost needed to overcome ripples in the battery voltage caused by hard acceleration or long battery wires. Remember, ripple voltage is hard on an ESC, adding the CC CapPack can greatly help reduce the load on the controller's on-board capacitors.
Cars and Trucks: With their high torque requirements - going from 0 to 100% throttle isn't easy on batteries or controllers - RC cars and trucks put enormous loads on brushless power systems. Use the CC CapPack to help your system power through the abuse.
The Castle Creations CC CapPack is designed for quick and easy installation. Users cut the soft silicone insulation on the battery wires - do this as close to the ESC as possible - and place the exposed wires in the channels on CC CapPack's posts. Check for proper polarity and then simply solder the wires to the posts. Use the included heat shrink to finish it off for a professional looking installation.
Note: All Castle Creations 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 the better. If an application exhibits more than 10% ripple voltage under peak loads, the user should consider using higher discharge (C Rating) batteries, higher current connectors, shorter wires, better gearing or a smaller load.
Multiple CapPacks may be used in an application. However, they should all be installed as close to the ESC as possible.
