Battery Power emonTX & emonGLCD

Submitted by warlock on Mon, 16/09/2013 - 05:45

Hi Guys,

I am looking at the options of battery powering the TX and GLCD and wanted to know from others their experience ?

I have a couple of UltraFire 18650 4000mha Lithium Batteries and am considering hooking 1 or 2 of them up to the units. These batteries at full charge are 4.2v and stop providing power at 3.2v much like a Lipo. Now from what I have read I can't just hook these up to the available battery solder pads and so I have to retro fit them to the USB port, What is the expected battery life or what is the battery usage like ? of these 2 devices.

I haven't been using my TX so much since I got the Li-Po so I can't tell about the performance.
