Turnigy nano-tech 2650mah 4S 25~50C Lipo Pack (USA Warehouse)

Turnigy nano-tech 2650mah 4S 25~50C Lipo Pack (USA Warehouse)


More than just a fancy name. TURNIGY nano-tech lithium polymer batteries are built with an LiCo  nano-technology substrate complex greatly improving power transfer making the oxidation/reduction reaction more efficient, this helps electrons pass more freely from anode to cathode with less internal impedance.In short; less voltage sag and a higher discharge rate than a similar density lithium polymer (non nano-tech) battery.For those that love graphs, it means a straighter, longer curve. For pilots it spells stronger throttle punches and unreal straight-up performance. Excellent news for 3D pilots! Unfortunately with other big brands; numbers, ratings and graphs can be fudged. Rest assured, TURNIGY nano-techs are the real deal, delivering unparalleled performance! Spec.Capacity: 2650mAhVoltage: 4S1P / 4 Cell / 14.8VDischarge: 25C Constant / 50C BurstWeight: 275g (including wire, plug & case)Dimensions: 145x44x22mmBalance Plug: JST-XHDischarge Plug: 4mm Bullet-connector  *The nano-core technology in lithium ion batteries is the application of nanometer conductive additives. 1) The nanometer conductive additives form ultrastrong electron-conducting networks in the electrodes which can increase electronic conductivity. 2) These additives create a superstrong ability for imbibition in the carrier liquid to supply more ion channels. This improves the ability of ion transmission and ion diffusion. Through improving electronic conductivity and ion transmission, the impedance is reduced and the polarization of high rate discharge decreases greatly.Advantages over traditional Lipo batteries;-Power density reaches 7.5 kw/kg.-Less Voltage sag during high rate discharge, giving more power under load.-Internal impedance can reach as low as 1.2mΩ compared to that of 3mΩ of a standard Lipoly.-Greater thermal control, pack usually doesnt exceed 60degC-Thickness swelling during heavy load doesnt exceed 5%, compared to 15% of a normal Lipoly during heavy load.-Higher capacity during heavy discharge. More than 90% at 100% C rate.-Fast charge capable, up to 15C on some batteries.-Longer Cycle Life, almost double that of standard lipoly technology.

I bought 2 of these about 2 months ago. I have been waiting on the motor and ESC for a new plane so I just started to use the batteries last week. One is bad. # 2 cell is low and will not charge. 30 day warranty had expired so I got stuck. Brand new bad battery.Using HK charger. So much for Nano-Tech and HK.

I had the same experience on one of their turnigy packs. I just ordered another pack and then sent the defective one back. I needed another pack anyway so it worked out, they got the defective pack back and shipped me a new one. Shipped it to a NJ USA address for return.

I assume you returned it within the 30 days and they actually replaced it! WOW, this is the very first postive responce I've ever heard for a HK product warranty of any kind. You are very lucky, buy a lottery ticket

lol, Yes, I bought one and called when it arrived and told them it had a bad cell so they gave me an address in the USA to ship it back to them. I did and about 3 weeks later I got a box in the mail. Maybe I should go buy a lotto ticket.

I'm not sure a one-month turnaround is a customer service victory but at least you did get a replacement!

I've had great experiences with HK on returns and products. The last item I sent back wasn't in stock, so they credited my account with bonus points instead. Pretty sweet I thought.
