Should we advise people to use Lithium-Polymer batteries in their transmitters?


When people ask us if they should use LiPo cells in their radios, should we tell them "yes" or "no"? Is it a good idea or a bad idea?

I always recommend that people check with, and follow their manufacturer's recommendations. Who are we to go against a manufacturer's recommendations? I certainly wouldn't want to be held accountable for giving bad advice and a TX is critical piece of equipment.

Maybe I'm being over cautious, but I'd rather err on the side of caution.

Lastly, I don't see what all the rage is either. Buy an extra pack for your TX or get a better charger and charge at the field. I have multiple TX batteries and swap one out at the field when necessary.

I went to 3 cell lipo in my JR2610 2 years ago no problems.

Lipo in a tx - an answer looking for a question.
Use whatever makes you feel like you know what you're doing.

My answer would depend on if I had any experience with the model of radio the person is asking about. Neither one of the poll questions is absolutely correct. It might just be a bad idea depending on the maximum voltage a radio can handle.

Honestly, what's the point? When the energy density of NiCad/NiMhs is nowadays above 2600mAh per AA cell, why bother? Heck, even my old, rusty Hitec Lazer 4 Tx can last 2-3 hours on its stock (800mAh I think) NiMh battery on a full charge. Besides the "because I can" excuse, what's the advantage? Seems to me, the risks far outweigh the benefits, especially when taking newbies into account.

That said, this is all well and good until Tx manufacturers start designing and producing LiPo or Lion powered Tx's. When they become as trouble-free as cellphones, then there won't be much discussion in this regard I think. But until then, why "fix" what ain't broke?

There's my two cents.

there's 2 more choices needed...

C) Depends on the radio

D) No point using LiPo, just use Eneloops or other low self-discharge NiMh.

Its not bright to stick LiPo in a JR X9303 or a Spektrum DX7. The LiPo can damage the radio and void your warrantee. (not to mention potentially causing the loss of control of a model in flight)

Some Futaba radios are specificly rated for 3S LiPo...

with the 2 choices provided in the poll... I was forced to vote no. But its dependant on the radio as to if its OK to use them... and the relatively recent development of low self discharge NiMh gives a better option for many radios.

I'd vote for the high-capacity Nimh. They will significantly increase transmitting time and can be charged with the Nicad charger. I think a lipo is overkill in this application.

I didn't see your answer choice in the poll?

"Yes, it's a good idea."
"No, it's a bad idea."

Use Sanyo Eneloops, Ray O Vac hybrids or other high quality LSD Ni Mh .

The problem is that you should charge LiPo batteries in a fire proof container. You have to remove the battery for every charge or make a fireproof compartment in your transmitter.

My Futaba transmitters with NiCad or NiMh have almost 3 hours of on time so I donít see why you need more. For those long weekends away from home I fly several transmitters so itís not a problem to charge one while I am flying other.

LiPo Ė itís just not worth the risk.

Thatís definitely the best solution.

Neither -- always YMMV; and, only if you're careful/capable!

I do w/diode in JR 9303 (72 & w/2.4 Spek Module); my freind in 2.4 JR 9303 w/o diode -- both of us since early this spring.

I voted yes. If you are careful with lipos, why would you be careless when used with a Tx?

Because happens. Why complicate matters when simple solutions exist? (Eneloop, Ray-o-Vac, etc.)
