Upgrade your Spektrum DX9, DX8 and DX7S radio with a Turnigy Intelligent Transmitter Pack. You'll spend less time charging and more time flying because unlike NiMh, Lipo batteries hold their charge for extended periods so they're always ready to go

Lithium polymer batteries last much longer than NiMH packs as they have a far greater energy density. The Turnigy DX Series Intelligent Transmitter Pack also features a built in voltage protection circuit, this circuit will automatically cutoff once the pack drops to 2.95v per cell ensuring the battery will not be damaged if you accidentally leave your transmitter switched on. The voltage protection circuit will also restrict charging to 4.2v per cell ensuring the pack can never be over charged.

Peace of mind charging, extended run times and Lipoly convenience like never before, Upgrade your DX8 transmitter with Intelligent Lipoly technology today!

Please make sure you change the low voltage alarm on your transmitter to suit a Lipo battery

Great battery for my Dx6 last a long time between charges and much cheaper than spectrum original battery
Keeps me flying all day ...
If you DO NOT have the option of charging this battery through your TX or you DO NOT have an 2S Lipo charger, then I would Strongly advise attaching an balance cable to this battery!
It's an awesome product too, by the way!!
Works great in my Spektrum DX9 Tx. Charges inside the Tx with stock cable. Fits fine. This batt lasts forever, more than two long flying days.
after connect the battery to my dx6 screen and logo blinks and radio turn of and on in loop.
this lipo ist the best for the spektrum transmitter.Quality is ver good, thanks HK
I have been using this pack from HK for a couple of years now, it had become tired so I purchased 2 more packs a few days ago. I am not using it as is, when it arrives, I open the pack by carefully removing the covering around the cable, unsoldering the existing cables, removing the built-in balancing circuit and wiring it as a regular LiPo with a balancing cable, so that I can charge / balance it through my regular charger. I trust this method better, just 15 minutes work and hope to get out of each pack another 2 years of usage.
It is a bit warring that I have been charging it now for about 2 hours and it doesn't reach balance point... I hope it is not a sign telling me that the quality of this has become questionable.
Using this lipo I can go a month in between charges. With the hihg capasity of this battery. Flying is great.
Bought one for my D9 Black Ed.
So far haven't experienced any problems with it.
The connector seems to be of type JST-EH, ordered some female connectors for making a charge lead for my charger in case I need to charge it with more than 200mAh provided by the charger that came with the transmitter.
very good replacement for cheaper price, you can charge these on lipo charger (non balanced mode) but you need a modified cable, just don't charge them too fast, their internal balancer cant handle it. I charged upto .7 c and it got full at 8.4, couldn't make the trickle charger included with the radio to ever do this.
It won't charge with any of my chargers it did discharge but now I have a dead battery. And no way to charge it did show 8.3 volts then the charger will stop with high voltage 20 volts.Charger works find on other batteries.
