I had a bad experience with one of these packs. Not sure if it was the 2200 or the 1800 as I have both from Hong Kong warehouse. The PCB connecting the three cells and the leads burnt out. The design relies on a diagonal copper track taking full power.
The glider was running a 40 amp esc so current would have been well under 40C. Only a few seconds at a time, not continuous. After the crash I initially thought the new ESC was blown, I posted it back for repair, then next day found the LiPo dead
I have two of these packs for my T-Rex 450 Pro and my HK450TT. These packs are great! They always charge correctly. They can be balance charged at 2C no problems whatsoever. The weight of the packs balances the CG of my 450's just nicely and they fit under the canopy just snugly. I fly mild 3D and these batteries have heaps of grunt - I usually only need to use 85 throttle to do 3D. I have Turnigy packs of various types and i have yet to have a problem with any of them.

Dissapointed, Spec pac size is incorrect, got 3 of these from hong kong for my E-flight Blade 400 and they all don't fit, pak size say's L 112mm x H 24mm x W 25mm & 200gm, but is actually L 112mm x H 35mm x W 27mm & 205gm, although they were cheep it was a waist of money, otherwise probably a good pak, I would'nt know, it sounded like it was good when I ordered, if i wanted my money back I would have to pay the big shipping $. :(
