4-Pack of Lectron Pro 3.7 volt - 300mAh 35C Lipos for Blade Nano QX 3D and mCP X

Works great cannot have to many batteries

These are being used in my Blade Nano QX 3D. They work and fit just fine, nothing else to report.

These batteries fit the Nano QX 3D but barely. They are relly snug (to wide) you have to pinch them a bit to get them in. Also the matched charger that amazon suggest does not work with these, they wont fit at all (the stock battery that comes with the QZ 3d doesnt fit either. In order to use the charger, you need to purchase 4 leads if you want to charge batteries for the 3d you need this:1s High-current Ultra Micro Battery Adapter Lead By E-flite (Efla7002um) but dont pay full price if you can help it.

Not sure is these were old or i just recieved a bad batch, but they dont work as well as my older batteries that are identical to these. Really dissappointed.

I use these for my good ol maps and tiny whoopsFantastic batteries.

Not good! After several charges the battery went weaker and weaker until they just stopped holding a charge all together! This was equal to all four of them. The Eflite battery that comes with the quad is still running strong.

A nice battery when you need a 300mAh size. It is a good quality battery.

Work well. Nano QX 3D flys the same with these, same center of gravity.
