Product Overview

The 3s Lipo Step Down Voltage Regulator for Radio Transmitter - Futaba/Hitec lets you "safely" run a lipo pack in your transmitter.

A 3s lipo pack is fully charged to 12.6v while most radio is designed to run on a 9.6v 8 cells NiMH/NiCAD (peak charged at 11.1v~11.3v).  A lipo pack will remain at its peak voltage for a long time while the peak voltage of a NiMH/NiCAD pack will drop quickly.  According to SpekTrum (Horizon Hobby), running a lipo pack in their radio systems will void your warranty and may damage the RF board due to the higher voltage.

Features:

  • Step-down voltage of a fully charged 3s lipo from 12.6v to 11.0~11.1v under load.
  • The voltage will remain at around 10.4v~9.7v throughout the capacity of the pack, this is a healthy voltage for any radio that uses a 9.6v 8 cells NiMH/NiCAH pack.
  • Easy to install, fully plug n' play.
  • Work with any lipo battery that has a JST-XH (Align/Rhino/Turnigy/FlightMax Style) balance plug.
  • Compatible with Futaba/Hitec radios that has "servo plug". Click here for JR/SpekTrum version.
IMPORTANT: this unit will also work for Hitec transmitters, however you MUST reverse the polarity on the plug, take a good look at your original battery and note the polarity (i.e. brown/red wires) and switch the wires accordingly. Do this at your own risk!

Advantages:

  • Prevent possible damage to transmitter when using high voltage lipo battery pack.
  • Provoke early low-voltage alarm from your radio preventing the lipo pack from over-discharging.
    • Technically the transmitter sees the low voltage at 9.0V, but in reality the pack is still at 10.6V so it is getting cut off at around 3.5V per cell which is a very safe cut-off for lipo.
  • Reverse current protection against charging lipo battery thru the transmitter's charging jack with stock wall charger.

***Never charge lipo pack inside the radio.  Always charge lipo out of the TX with a lipo balance charger***
