[NSRCA-discussion] Castle Creations CapPack

[Ronald Van Putte]

In my installation, I could have cut at least 5" off the wires between the ESC and my arming system, but I just coiled it back on itself.  I wonder if I shouldn't cut those wires and resolder the plug, so there's a straight shot between the ESC and the arming system.

The product information on the CapPack says, " 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 8 inches of length to the battery wires."

It also says, "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. Remember, ripple voltage is hard on an ESC, adding the CC CapPack can help reduce the load on the controller's on-board capacitors."

I wonder if reducing the leads might alleviate the need for the CapPack.

A lot of the speed control manufacturers (Schultze in particular) are very specific about the maximum length of the leads from the batteries to the speed control, as the max current and pack voltage increase, the length of the leads becomes more important.  The CapPack from Castle (and I think Jeti or Schultze have similar products I've stumbled across) ensures a smooth delivery of voltage to the speed control in situations where short battery leads are not feasible.  I haven't seen an EP pattern ship that needed it, even with arming switches, people are cutting their wires shorter to save weight...
