Eachine E011 Transmitter Battery Mod


The Eachine E011 transmitter takes in 3 AAA batteries. But alkaline batteries almost always suck and Eneloops are rather expensive. And they often tend to inexplicably disappear. Besides, I have a lot of LiPo batteries that I use on quadcopters so it makes sense to make use of them in other battery-operated equipment where possible. This mod is simple and easy and should be applicable to most transmitters similar to the Eachine E011’s. Plus you should still be able to use AAA batteries.

Parts and Equipment

For this mod, you need the following:

  1. Molex battery male connector
  2. LiPo battery with Molex battery female connector
  3. Soldering iron
  4. Soldering wire
  5. Wire snips
  6. Philips screwdriver


  1. Unscrew the back cover of the transmitter and thread the battery connector through one of the holes in the battery compartment.
  2. On the other side, solder the connector ends to the corresponding terminals. Red to red, black to black.
  3. Connect the battery and you’re done!
