Common Sense RC (12 Pack) Lectron Pro 3.7V 180mAh 45C Lipo Battery with Micro Connector for Blade mCX, mCX2, mSR, mSR X, Nano QX, & UMX AS3Xtra

Very pleased with the performance

I've had quite a few have the black plastic piece fall off and several had the power connector fall off. I could glue the black piece back on but had to pitch the ones where the connector came off. I also don't notice any more flight time or performance over the stock 150 25C and for not much more I can get 150 45C that do perform better.I gave them a 2 because they aren't complete junk but I won't be buying them again.
