Cecicebb 3.7V 150mAh Lipo Battery for Syma S107 S107G Helicopter S107G Battery 5 Pack 651723 Lithium Polymer Battery1

Fantastic! They battery just fine! Every batteried

Perfect

at least

I have 4 of these each independently powering a few motor controllers, IR receiver and a tiny pico, in a very tight space!

These looked fine and arrived well packaged, but even though they are supposed to be the same as original, I could not make them work in either of my two small helicopters. I tried 3 of the 5 batteries received. They each charged to 4.12v, which I think is ok, but the helicopters would only lift up about 2" off the floor and scoot around. I tried them in a 104 copter as well, the one with side pods, just to see if there is something wrong with the 107, but it was the same result. Anyway, there is nothing wrong with the copters, these batteries are just too weak to fly them. They were physically the same size as the original, and the markings matched the description, but they just don't work.

They work but are WAY bigger than I thought they would be. I only bought these because there were reviews of people using these for Anki cars. The batteries are slightly too big for the car. By time I get it in the car the battery is pressing on the gears so the car won't move

I used these to replace the factory batteries on my Anki overdrive cars. Installation was easy and these last a long time on one charge.

size doesn't match description, returned
