UBEC/tapping from 4s w/balance tabs?

[JeffEmbracedDC]

So, I could always use a UBEC...

Though, let's say I wanted a 7.4v output (at about 3amps) could I just tap directly off of the balancing tab? I understand that servos may not be rated for 7.4v, but that's beside the discussion. The question is just - can I pull 2S (7.4v) voltage (at 2-3amps) from the balancing tabs?

Thanks.
