They (my LHS) is suggesting ROC batteries. I haven't heard of them yet but they say they are pretty good, a little more money but better quality. I started a thread to see is anyone has heard of or used them, not much of a response yet. I want to give them a try. If anyone wants it, I can give you my LHS's number, I hope that's okay with Tom (the owner, really great guy!).

I do have 3 4s 2200mAh 30C batteries, not a whole lot of cycles yet, and 2 3s 2200mAh 40C batteries. One of the 3s (each with about 30 cycles) is loosing a cell.
My LHS has a 1000mAH 3S 30C ROC battery for $12.99. It is virtually the same size as my current 850mAH 30C battery in my 3D foamy, so I will give it a try this weekend (weather permitting).

I also struggled a bit to find the website/specifications for these batteries ... here it is

BTW, if you can hold off a day or two, mine should be arriving shortly. I want to make 100% sure that they work for the sky lipo, so I can report back once i get them.

Cub Flyer - just realized that I owed you an answer. The Items I ordered work perfectly for the Sky Lipos, so order away!

Sky LiPo's are VERY poor batteries.

I bought 7 Sky LiPo's, 4 3s2200 and 3 3s3300. They have ALL gone bad, less then 12 flights on each battery. Same condition as stated above. Good power for 30-45 secs, then they die off.

I will stay with ThunderPower from now on.

My local Hobby Shop stopped carrying them.

I would recommend Turnigy from Hobbyking.

I've heard the same about the Sky's. I've heard good things about ROC's and started using them, or at least I've got a couple. Not enough time on them to give a report though. Look them up!
