If this is the first time you have used Lipo batteries, you should know, Lipos are quit sensitive for discharging under a certain voltage level. I case you have discharged this pack below 3.5V for each cell, the battery pack will be destroyed and cannot be charged again. One thing you might want to try is, to charge the battery pack without balancer. This MIGHT work but can also fail. One thing you should NOT try is to charge this pack from another pack - just a few seconds to give the pack a little charge, so minimum Voltage is regained and charger will detect correct voltage and start charging again. BEWARE - LIPO batteries can explode and will start burning when not used or charged in correct way!
It does not have the correct connection for the transmitter and it would probably be a bit too big too.
The "Turnigy 2650mAh 3S 1C LLF Tx Pack" is used a lot with the 9X, just have to make sure you have the polarity right as the black plug that you use to power the 9X can be put in upside down...
Hope that helps

i recieved 3 batteries last week on 25/8/2009, one is very good and balances well, the other two batteries had one cell each that read below 2.5 v. these cells don't charge over 3.9 v causing the overall voltage to drop very fast, the readings of one battery when i recieved is:
Cell 1 had a voltage of 3.85v charged up to 4.20 v Cell 2 had a voltage of 3.86v charged up to 4.18 v Cell 3 had a voltage of 1.9 v charged up to 3.9 v

Good value for the price but only 3 stars because I suspect performance is a little overrated. Great when fresh but noticeable loss of punch midway thru flight. Now beginning to swell (just a little) after about 15 cycles. Also heavy and bulky for the capacity.
Used on Precision Aerobatics Katana MD and Addiction with appropriate IPAs and props. Never been discharged under 11.5v. Max draw on either plane 40A, well within spec for the battery.
Ordered 2 packs.. One had a bad cell on arrival.. The 2nd fly well in yhe Easy Star but requires balance charging after each flight as one cell drains a bit faster then the rest. .1v lower when discharged.

I checked the capacity with a constant load of 20A and the result was exciting: 2220 mA and the drift of the cells was quite low. Also lipomon from rctool.de fits well to the balancer connector.
