MAX BEC 2 is designed to power the receiver and servos in the model. MAX BEC is a linear voltage stabilizer with an adjustable output voltage. The output voltage is set using a jumper and in one of four positions: 5,0V, 5,4V, 5,7V or 6,0V. MAX BEC can be powered using NiXX and Li–XX cells. MAX BEC also gives an indication of used capacity of the battery with four LEDs.

Part of MAX BEC is an electronic switch, which uses a highly efficient type of MOSFET transistor. The main benefits of the MAX BEC include a high voltage rating (to 12 cells NiXX) and low current in the off state (170 μA). The analog voltage stabilization does not contribute to radio interference.
