Turnigy 4000mAh Spektrum Compatible DX9 DX8 DX7S Intelligent Transmitter Pack

Turnigy 4000mAh Spektrum Compatible DX9 DX8 DX7S Intelligent Transmitter Pack

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, Lipoly batteries hold their change 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!

This build in cut-off circuit doesn't seem very logical to me. If I am flying a plane, and the battery gets below 2.95 v/cell, I would rather damage the battery than my plane. In my opinion a transmitter must never have a cut-off system. It should run until the battery is totally drained, so you have a chance to save whatever you have in the air at the time.

Set your radio low voltage alarm to warn you before this happens. Allowing your tx battery to get this low is not the fault of a battery or even a batter cut off. It's being irresponsible to your aircraft and to those around you. This is why there are preflight checks.

Go you have a charge lead for this item "Turnigy 4000mAh Spektrum Compatible **9 **8 **7S Intelligent Transmitter Pack" Thanks John Shovlin

This pack charges by plugging the stock transmitter charger into your radio. Make sure to select "lithium" as your battery type in the transmitter. A standard charger will not charge this pack due to the intelligent circuitry. You charger will give you an error message. I made my own charge lead and tried to use an iMax B6 type charger, and it would only give an error.

I've made a stand for te ko propo ex2 to fit this battery and i'm charging it using iCharger Duo without balancing. I'm doing it at a low charging rate and it's working fine. I go racing/practicing twice a month and have i've charged it 3 times in 6 months -

I had to take the foam out of the back of the battery compartment to make it fit. Charging for first time now.

awesome battery.Just charged it at 1.5 amps and took an hour on my turnigy 8150 charger.battery came off at 8.2 volts.when you turn your radio on go to system settings and switch the battery power from nimh to lipo and the radio will adjust the low voltage alarm.HK hit it out of the park with this one,50 dollar savings over spektums battery.

Super produit, et beaucoup, beaucoup moins cher que spektrum qui abuse un peu sur le prix d'un simple lipo 2s. Plus besoin de recharger tous les 4 jours. En passant la radio en mode lipo, la charge se coupe toute seule. Parfait ! Great product, and much, much cheaper than Spektrum abusing a little on the price of a single 2s lipo. No need to recharge every four days. By the way radio lipo mode, charging turns off by itself. Perfect!
