For those modelers looking for power for their receivers and servos there are three methods. One method is to use the Battery Eliminator Circuit (BEC) that is part of the Electronic Speed Controller (ESC). If the ESC does not have a BEC or if the power is for a non-electric powered model, then one uses either a separate battery or a separate BEC. Below are both receiver packs and receiver power packs with BECs. Since servos run on either 4.8V or 6V, a two cell Lipo (7.4V) alone is too much power for a receiver pack.
To take advantage of the benefits that Lipos bring, we created power combos. Each one lists the output voltage and total capacity. Just plug the battery into the BEC and then plug the BEC into the receiver. Plugs are included when necessary for each combo.
Warning: You must remove the battery from the BEC after each use. Failure to remove the battery will cause the voltage of the battery to drop below safe levels. Also, charge the battery outside of the airplane.
