I am in contact with the manufacturer. They gave me a handful of them for testing. So far I am pretty pleased.
But there will be an official introduction of the manufacturer with further details soon.

I met them in Shanghai in Sept for the Shanghai Int Model Expo. They made some claims that were a bit much. Not proper for me to go into any details, I will say that I look forward to see the long term testing as this is where the quality of the product will be determined. Most packs looks good at first then after 30-50 flights they are pretty much shot. Most won't even make 100.

Julez, do you have the ability to test for actual capacity and C rating?

Julez is correct, more details will be coming very soon on RC Groups.
RC Accessory is also right, only long term testing can confirm real quality!
All stated specs are honest, please feel free to test actual capacity and C rating according to manufacturer's standards.

I'm looking forward to seeing some more testing and reports from users. I'd like very much to purchase 4 4S5000 packs for my pattern plane if things look promising.

I assume you are a representative of the manufacturer. Could you provide details of the "manufacturer's standards" you use to determine capacity and C rating? Many of us here would be interested to see what those test procedures are. We have been asking for something like that for a long time, but (as far as I know) no such thing has ever been published.

Thank you.

As a surfacer, I use 3s 5K. Looks like these will be too wide at 52mm.

It would be interesting to know how many manufactures were out there.
Like back in the day when I sold electronics there were only a handfull of manufactures that made all the vcrs mybe times have changed as it was along time ago.
I also wounder what drives the lipo world.
