Default To BEC or not to BEC?

That is the question!

Can anyone explain to me the pro's and con's of having a BEC dedicated battery in a boat as opposed to running the RX off the main drive battery.

Does the use of NMHI or Lipos make any difference when choosing one of these options?

Thanks, Brett.

Your not flying an airplane and even if you were, most prefer to use built in or separate bec versus extra pack. Save weight.

+'s Saves weight,
saves space,
one less thing to charge
One less thing to mount

-'s can behave funny with some ESC's when voltage is increased or decreased

Just curious as to why there are two types when obviously the BEC type is the better option.

Battery Eliminator Circuitry is not the better option in all cases. In the past no serious racer used the BEC because they bled through too much motor interference and caused serious glitching. Using a dedicated receiver pack (not a "BEC" pack) eliminated that problem. Also older BECs did not supply enough current for the more powerful servos, a 5-cell receiver pack does.

Most serious racers still use a dedicated receiver pack, but the newer opto-BECs claim not to have the issues seen in the past. If they can supply a full 6 volts and 5 amps to the servos then I might try one, otherwise I'll keep my receiver packs thank you.
