Whow, right after I typed that out, the voltage fell to 12.6volts.

I wonder if it just sits idle unless the reciever is also on, kinda like a sleep mode?

No, I don't think it does... when I used AA alkalines, you turn the switch on, then after a 2 second pause, the LED on the back lights up and the voltage suddenly drops. It must draw a good amount of power.

I took the Summit out today and the cell phone batteries worked flawlessly in the Tx. Awesome! Let see how long they last on 1 charge now....

What is the mah and voltage on that pack?

Sorry to hijack the thread, but I was thinking. What about simply adding 3 diodes in series with the battery in the DX3r? Each diode will drop around 0.6v at the current the radio draws, which would drop about 1.8v total. On a peaked 2s lipo, the radio would see 6.6v, which is fine (my freshly peaked 5X NiMhs have peaked higher). At LVC of 3.3v/cell, it would be 4.8v, which is the nominal value of the 4 X NiMHs the radio is designed for. Some regular 1N4001's would work.

The downside is that you'd have to add some kind of new charging jack so that the charger will not have to read through the diodes. BUt that should be done anyway to allow for balancing of the 2s pack.

Just an idea...

Or just use 2s M1 pack? :wink:

Still a tad too high. Peaked, they're 7.2v. Maybe with a diode in series.

The advantage to using a diode is that it drops roughly the same voltage all the time and therefore can use the radio's voltage display fairly accurately.
