4A UBEC w/ Low Voltage horn=UBECH

This isnt a normal UBEC.
It can handle 4amp draw and comes with a low voltage warning buzzer. Should your pack drop to below 3V per cell the buzzer will sound, telling you its time to land your plane before you kill your expensive Lipo pack.

The UBEC comes with an extended section of PCB, you can use this to help mount the UBEC or you can simply cut it off.

Although this is a UBEC and can handle up to 23v, its warning system is only designed for 2cell. Some would consider using a UBEC for 2cell as overkill, however it ensures a stable current, less heat and a higher amperage can be used.

This UBEC can be used with up to 23v input. If you use a 2 cell pack only, it will also warn you if your cells drop to 3v per cell.
