You quickly get used to the '2 switch preflight', but if the OP wants a switchless solution, it is possible as to do as well.

I have personally lost my 10s (2x 5s) and canopy in flight and didn't even know I had lost the power pack. I landed and found the canopy but never did find the battery. I would never fly without a dedicated pack for the receiver and servos.

I use the same setup as Itc. On my high voltage systems I run the Jeti Mezon BEC at 8.0 volts and have the Jaccio regulator set to 7.5 volts. I also test, one switch at a time before every flight. I can see each voltage on the transmitter to confirm all is okay. The downside of this is you will eventually meed to charge the 2s LiPo. I'm considering removing the regulator and let the Mezon BEC keep the 2s LiPo charged to 8.0 volts. I have run the BEC as a battery charger for hours and hours on the bench and it has worked flawlessly.
