JETImodel MAX BEC 2

The JETI Max BEC 2 is a battery switch with voltage regulation. The ON/OFF switch is designed in the form of an MPX bridge plug. For maximum switching reliability, the ON state is achieved when the MPX bridge is removed. 2 independent 2S LiPo / LiIon batteries can be used for power supply. The incoming voltage and the currently active battery are displayed by a row of LEDs.

Technical information on the subject of maximum current load capacity for linear voltage regulators (not S-BEC):

The maximum current is the maximum power loss in watts divided by the difference between the input voltage (battery voltage) and the set output voltage. This applies to normal cooling air discharge, so never pack linear voltage regulators in foam or similar!

Example here:
max. power loss with MAX BEC 2 = 20W
battery voltage LiPo = 7.2V
set output voltage = 5.4V
max current > 20W : 1.8V (diff. voltage) = 11.11A
