Received battery in perfect condition.
All cells charged to 3.90 volts.
Description measurements are accurate.
Balancer leads = 48mm
Futaba discharge leads = 120mm
JR discharge leads = 110mm
Fits perfectly in my Futaba 7C.
Charged to 12.6 volts, and it works like a champ!
No more hassling with that high maintenance NiCd.

I'm using a bantam 6-10 charger on lipo. Charged this lipo at 11.6v, 12.0v and 12.6v on different occasion. I used this on my DX7/Hitec7 transmitter. I used an infrared heat sensor to measure the temp of my transmitter using first the nimh/nicd fully charged at 11.6v and then this lipo fully charged at 12.6v. I found that no significant temp. change on both transmitter after using the lipo fully charged at 12.6v. The hitec7 module will get warm but this is normal either using the nicd or lipo. On DX7 no warmth felt at all (measured by heat sensors). If you are still afraid of burning your transmitter or because of voiding the warranty, you can just charged this lipo at 12.0v and still have an 80% capacity of this lipo and still gives you hours of flying time. I think the problem of voiding the warranty has to do with overdischarging this lipo below 9.0v which in reality their's a possibility of starting a "fire" inside the transmitter. My suggestion as I stated earlier is DO NOT FLY WHEN THE LIPO IS AT 9.6V (consider the battery as discharged at that point). Your warning should be start at 10.5v and recharged it at 10.v. (note that your transmitter LVA is quite low for lipo)
Note below my lipo from fullcapacity charge to discharge charge using my bantam charger:
12.6v = 100% 12.3v = 90% 12.0v = 80% 11.7v= 70% 11.4v = 60% 11.1v= 50% 10.8v= 40% 10.5v = 30% 9.9 = 10% 9.6v = 0% ...
remember the 80% rule on lipo.. recommend to stop flying/using them wh

whoever plug a jr/spektrum connector to a "hitec" transmitter and found out he has a blow out (ouch!) need to learn basic electricity specially DC electric! the standard norm is Red wire =Positive... Black wire=Negative but u still going to watch out since alot of manufacturers doesn't use the "standard" color... jr/spektrum and others used brown wire = as negative so u have to watch those color coding! also on hitec transmitter, it has a safety tab if you used their "battery" so that you can't plug them in reverse... the problem is the jr/spektrum connector will fit on hitec BUT on reverse connection to use it "properly" ( please look first how your original hitec battery plug polarity i.e. positive on positive, negative on negative plug)so that you wont repeat the same mistake.. make a mark on your transmitter which is positive and negative.. please use common sense for any DC electric wiring!..
P.S. another tip: those people who are afraid of voiding their warranty and afraid that 12.6v will fried their transmitter, use a good charger that has a "storage function" like bantam.. i charged my lipo at 11.4v using the storage function.. it will not fully charge your lipo but hey a 11.4v lipo is not the same with a 11.6v nimh/nicd since they discharge differently (lipo is more efficient than nimh/nicd) which still equates to hours of uses compare to nicd/nimh before needing charges...
btw, if you don't have a storage function, you can just watch your charger charging t

I have this pack installed in my Futaba 9C and Hitec Eclipse 7 transmitters. I have been flying this setup for about 3 months. I installed 3 diodes in series with the positive lead between the pack and the Tx connector. This dropped the voltage by about 2.4V. Adding the three diodes:
1) supplies the expected voltage required for the transmitter
2) allows the low voltage alarms to function correctly and
3) isolates the Tx charge input jack forc

I tested this both on Hitech 7 synthesizer and DX 7 with no problem. With Hitec make sure you check the polarityv before plugging it to avoid short circuit.
note: Hitech low voltage alarm 9.3v programmed by manufacturer. DX 7 low voltage alarm 9.0 programmed by manufacturer. I don't recommend this setting. My suggestion is recharge the lipo at 10.v as your safety window. At 9.6v and below, consider it empty. The lipo will discharged fast below 10v. so be cautious!!!

Super. 20 heures d'autonomie et recharge en moins de 2 heures.
J'ai équipé mes radio MX12 et MX16s sans problème. Moi qui passe beaucoup de temps en réglage c'est impecable.

| Finally able to go out all day with out having to top up the battery in the transmitter. Using a JR X9. Would highly recomend the change to this battery.

Put one in my DX7 over a month ago and despite siming and flying nearly every day, I have yet to charge it - as a comparison, I was having to charge the original pack two or three times a week. It's also a great fit and doesn't rattle around like the old one.
Thoroughly recommended.

Have been meaning to try a lipo in a TX
for some time. This was Just what I wanted.
It has Balance taps and I ALWAYS balance
charge my lipos.
I've been using this for over a week in my
Polks Traker III TX with out a hitch.
Compared to the std 900ma Nicad this is
a DREAM ! It lasts for DAYS !!! and
It Fit as advertised !
Because I have an old CSRC balance charger I had to reverse the balance taps.
That was easy to do with a small flat jewelers screw driver. Just press down and remove the pins, then replace as
necessary.
I do that with all my Lipos.
No more silly piddly wallwart chargers for my TX !
I'm going to get another for my DX7.

| Bought two for my Graupner MX-16 an for my Futaba FF10. A little sanding was required on the JR plug to fit within the MX-16, but no hassle at all. The dimensions of the packs are perfect for both transmitters. Just what I was looking for, great!

| One thing I have noticed about the above reviews is that no one has said one of the best features of Tx LiPo s is that they DON'T discharge very much by themselves when not being used. Nickel metal/cad batteries discharge quite rapidly when not being used. This is why LiPo s last so many weeks in a transmitter if they are used or not used. Personally, I won't use anything but LiPo s in aircraft, racing model boats or Tx s. I even use 2s LiPo s fo

| It sits perfectly in the JR X-3810 radio battery compartment although a male plug needed to be soldered for the connection. I used the cell without charging first and it gave me sufficient power that read 11.6v on the radio LCD display.

Great battery.
Great deal!
I put a couple inexpensive (IN4001) $1.00 @ Radio Shack diodes in the + line to drop the output voltage a little. Many are using 1 diode or none with good results. I'm Mr. Conservative:-).

if anyone wants to know: it fits in the dx3.0 and jr sx3 controllers.
i expect it to work great - managed to get in before the hoards :P
once again hobbycity rocks.
btw, they came shipped within 0.001v. thats just perfect :)

| It doesn't get any better than this...Fits absolutely perfect in my HiTec Optic 6 and that includes snapping the cover on w/No hassles. This TX takes full 12.6v just fine...just means i can fly all day on single charge. This battery is the ONLY way to go! Get one and you'll be happy you did.

| Works like a charm on my DX7 without any special diodes or alterations. Hours of flying time AND idle time and still at 12V. Not having to charge my radio is one less major important task to worry about.
