Got few phone calls and emails from guys who need more than 15 servos with they Jeti Central Box 210/220
Here is configuration that uses power from Port 9/10 (2x7A) from CB220 for Central Box 100, this way you can have up to 20 high power servos connected to the system. If you connect Telemetry to the CB100 and use CB100 only for nonessential functions you can get away with single power lead and go up to 22 servos.
