I bought 2 of these: http://www.dealextreme.com/details.dx/sku.7621

They came in within a reasonable time for being shipped from China and without any problems. So far I have 8 cycles on one and 9 cycles on the other and seem to be pretty good batteries.

I fly them on my 12 oz Blu Baby (a scratchbuilt foam 4 channel Cessna 182 lookalike) using a 24 oz Blue Wonder 1300 KV motor and 8.25x5.5 SF prop and get around 20 minutes flying time per battery.

The next time I need any 2000+ mAh batteries I'm going to order a couple of these from them: http://www.dealextreme.com/details.dx/sku.12821
