Hi You all:
Thanks for the inputs, let me tell you some more facts.
1.- This is the charger I have been using for years…the wire for the plugs is thick enought and I have been using ithem with High capacity packs for 1/4 scale aircrafts as well, never a problem and always checking with a voltimeter, after before and after charge.
These days I should get at home the turnigy acucell 6, that will provide me a good tool for cycling batteries,a dn allow li po and li iom packs to be charged.
I got very tempted with the idea of Li ion cells. So in my next trip to US, that should be soon at the end of october I will order some packs for 2 or 3 2.4 ghz Tx.
I wonder if there is a chance to use them in regular Am of Fm futaba transmitter, for my airplanes, cause a PCM 7 ch futaba last barely one morning of consistent flying al, the time, it seems that too many functions consumes a lot of energy. but 3.7v x 3 = 11.1v…so i wonder if the Tx can handle that voltage. If not, where Culd I get a voltage regulator.
It will be usefull too, because some winch servos can take up to 7.2 volts, so a “Y” harness will be desirable, and a voltage regulator for the transmitter will be needed, or not???
2.- The cells are the same brand I have been using for the IOms since two years ago, no problem on that.
3.- The cell are pressed into the Tx where they fit very tight, so no need for soldering. (I did that in a Futaba attack 2ch and when i went out of charge at the pound, i had the problem i could not make a emergency replace with alkaline cells from the shop in front of the street…that is bad luck!!)
4.- The Rx pack that i used for tests all the time is a 5 cells 2400 Mha, soldered cells, that works perfectly.
5.- The cells I used where brand new, I plugged in the charging plug and the light in the charger turned on. i asumed that the cells was being charged and went to sleep. yesterday i replaced the cells for others i was using in another Tx and the radio was working fine, SO…
The problem was that for some reason the Tx did no allow me to charge the cells inside directly trough it.
I will check on that later, cause I am preparing my stuff to go to sudamerican Championship tomorrow ( october 9th to12th, Rg 65 and IOM one design ULY)
So I was thinking to solder some wires directly from the batteries to the plug female at the side of the TX, jumping the internal circuitry.
That will solve the problem from the root. cuase now does not matter which cells i place into the trnasmitter, the charging led in the charger will not tur on, so the problem is beteewn the cells and the charging outlet in the Tx.
At least now i have the problem localized!!!
I would like some inputs about using the Li Ion cells for regular Futaba transmitters and eventually for Rx packs.
