Trex and trex jr powered by Lipo batteries


how would one go about powering trex or trex jr via a Lipo battery. the battery is approx 7.4v 4000mah .
should i use a BEC as in the Novak BEC’s

Please advise.

thank you Dave

Hello Dave,
The TReX has its own regulator and does not need a separate BEC. You can use the BEC feature of the TReX to power an R/C receiver from your LiPo, but it is not sufficient to power servos.

All of this information is covered in detail in the TReX User’s Guide, so please make sure to look that over if you have more questions.


great thank you
