no and yes.
Care to elaborate or are just going to keep us in suspense?
Oops, sorry about that monkey nuttz. Guess I was demonstrating my uncanny ability to NOT understand what I read.

Used 3S lipo in all my TX in the past 4 years. I have yet to encounter any problem. Tx included JR9303, Hitec Optic 6, Futaba 9CHP.

I did added diode to drop the voltage by 0.6v when I first tried this on Hitec Optic 6 at 2006. However, it was later removed as diode was consuming battery power that could be used to power the Tx.

As for charging, of course the mfg supplied all charger can no longer be used. I have always used balance charger and never had a problem. My Tx powered by lipo only require charging 2 to 4 times a year.

Most electronics these days have enough tolerance built in, especially with them using regulated power supplies. I work with class D amplifiers that are rated with a 12V input power but we regularly run them on a 16V system. 16V system has a float voltage of 19.2V, quite a bit of difference but then again today the good stuff comes from Korea .

If you are really concerned about it you can replace the voltage regulator in the DX7 with a switching regulator. Known as the DX6 mod.
The Mod is the same on the DX7, I did this mod to my DX7 and it has been working great. The best part is it can take up to 30 volts input and your battery will last even longer and no worries about heat damaging other electronic components in your TX. All this for less than $20.00.

See these sites for info.

I’ve been away from flying for a bit. I’m still using a 72mhz radio.

- JR XP6102 TX Rhino lipo 2620
- R770 PCM
- R790 ul PCM scan select

I have not charged my TX (JR 6102) for many months. I’m running a Rhino lipo 2620mah TX pack which I balance charge outside of the radio. The voltage was at 11.2 when I turned it on and started getting my models ready to fly.

I can’t remember the voltage range that I decided on. I did a little checking, and I think I will put the lipo in the TX charged at 11.8 volts and re-charge when it gets down to 10.5.

Does that sound like a safe range?

Many people put lipos in at full charge (12.6v) and do not have problems, but I feel safer putting it in my radio at a lower voltage.

Any thoughts?
