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 are a bit disappointing, bought these for a scratchbuilt balsa RC model of about 40 gram weight. They should be able to spin a geared 716 coreless propdrive at full speed for at least at a few minutes, but they fade about two minutes on the test stand. I'm assuming that a 25C rated .15 amp hour battery should be able to easily power a motor drawing 1 amp at 3.7 volts. OK let's be conservative these are actually 12.5 C and I should be able to draw at least 1.5 amps at full volts without the voltage dropping. But they don't, they aren't much better than the 145 mAh 1S batteries sold back in the mid aughts. That you get 5, I suppose makes up for their eminent short lives.

I got just what I ordered

Just won't make a Syma helicopter fly. Chopper won't exceed 4 inches.from the ground on a full charge. None of the 5 batteries ordered worked. Have the same specs as the originals but obviously not the performance. The few old original batteries I had would work fine when I reinstalled them into the choppers I tried to upgrade with brand new batteries. Very disappointed.

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.
