The Turnigy nano-tech round single cell series are the perfect solution for many applications where space and weight are at a premium. These round Lipoly Cells can be soldered together to make compact RX packs for instance in a configuration and capacity that is perfectly suited to your application while giving you the peace of mind of nano-tech performance
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.
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.
* NOTE: Only cells of the same make and capacity should be connected, also only ever connect multiple new cells, never old and new.
Yes if you want a very light battery pack but on the downside it is not so many mAh in this cells only 1200 and in 18650 cells with similar size you can have round 3000mAh at 3,6 volt so you have to make the decision it is cheap cells and Nano-tech is good quality
Most laptop batteries use 18650 size cells. You can get those in 3300maH, and maybe more for low drain types. Or you can go with different chemistry in 18650 size, and get much higher capacity, but the discharge rate may be a little on the low side.
Lips are too risky for laptops... The charging wiring/ protection circuitry can be tricky in the org. packs, the laptop is hooked up for days, lots of heat being generated/ bad cooling => FIREHAZARD!
If you want DIY laptop packs, use PROTECTED Lilo cells, these come for cheap from eg. DealXtrm, and the energy density is almost the same.
If you charge them with original laptop LiIon charger, they will never get full charge at first place. Then there is heat issue which kills LiPo rather quickly. Round cells have a lot less surface area than flat pack, so cooling is ineffective. But I see I will be stuffing those in flashlights etc, where they can't get hot. :)
These battery's are better than a regular Nano tech cell . Have replaced the cell's of a dead 3s lipo pack and used the soldering print for connection the balancing and charging plug . Longer and more constant power .
light weight. soldered to a 4s pack for a 13Amp drive. You get a cubic pack, wich I needed in this case instead of a long flat pack.

Got this to put in a dlg blaster for rx to replace a 350mah 2 cell and it's great for that purpose I can now fly for 5 hours instead of 1hr30 if my arm can stand it lol, from storage volts to charged is about 450mah and that's all I've done so cant comment on full capacity but should be fine.
