ESC with 7.4v BEC?

[Monkeysmate]

Do people worry about getting an ESC with 7.4v BEC? in our family fleet of three 1/10 buggies, only one ESC has a 7.4v BEC output, with the other two only 6v.
I'd not even thought about it until I was reading the manual for one of them...
Is this worth worrying about for the average mear mortal?
Thanks

7.4V bec is for those high voltage servo. i suggest you stick with 6v bec unless u have high voltage servo on that car.

The g-force 160 esc have 6 volts and 7 volts Bec output also 5 amps not 3

As the guy above said check that u have high voltage esc and receivers
