Turnigy Nano-Tech charging rate

[cjcj1949]

I've just bought a Turnigy nano-tech 450ma 65-130C

Turnigy nano-tech 450mAh 3S 65-130C Lipo Pack (E-flite Blade 180 CFX) (UK Warehouse)

The last nano-techs I bought could be charged at more than 1C, but the new batteries don't mention a charge rate on the battery. The information with them limits charging to 1C. This seems strange as the sales info mentions up to 15C. Has charging over 1C been causing problems, other than a slight reduction in life?

The charge rate on the web site's listing for the battery says 5c.
I'm guessing if they came with a leaflet that it's probably generic battery safety 'bumf' that would be supplied with any battery, so they no doubt default to the lowest charge rate applicable to any of their batteries.

I have 12 of these so don't usually need to charge at high rates but sometimes go to 2C.
If you re-read the info for them you'll see that the info regarding the 15C rate isn't specific to theses packs but to their nano-tech type in general.

Advantages over traditional Lipoly 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 1.2mO compared to that of 3mO of a standard Lipoly.
• Greater thermal control, pack usually doesn’t exceed 60degC
• Swelling during heavy load doesn’t exceed 5%, compared to 15% of a normal Lipoly.
• 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.

The nano-core technology in lithium ion batteries is the application of nanometer conductive additives. The nanometer conductive additives form ultra-strong electron-conducting networks in the electrodes which can increase electronic conductivity.

These additives create the 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.

I couldn't find the specific charge rate anywhere, thanks.

It's listed in the "Product Config Table" along with the dimensions which is below the description and above the order section.

I've already read through that a few times....
