Blomiky 2-Pack 3.7 Volt - 150mAh Li-Poly Pack Replacement for S yma S107 / S107G Helicopter Some Mini RC Cars / S107G Battery 2

I had not used my S 107 helicopter in a long time and the battery was shot. Bought these as they were the same specs as the original. Quick soldering job and the battery was replaced. Charged it up and the copter was flying like it did when new. I would buy these again.

Battery is a replacement for a mini helicopter. It arrived charged and ready to go. Hardest part was soldering the new battery to the helicopter.

Same dimensions as the OEM Syma S107G Helicopter's battery. Snip, solder and fit with a little piece of mounting tape - took about 15 minutes.The wires that come with this battery are thicker then the OEM one so they needed to be routed around the sides of the battery. You could remove the thick wire completely and solder the OEM leads directly onto the battery but run the risk of overheating and damaging it.Performance: Out of the box it measured 3.93V and gave me about 3 1/2 minutes continuous runtime. After cycling a couple of times it's up to about 6+ minutes continuous runtime which is about par for the original battery. Time will tell with respect to longevity.Paid $ 9.99 for 2 pieces. A new chopper currently retails for about $ 25.00 so it's worth it to keep the old girl flying.

This is the second time I’ve replaced the battery in our Syma helicopter and after this replacememt it works better than ever. Cheaper than buying a new one and my batteries were wrapped in a new lens cleaning cloth that I’m now using to clean my shop safety glasses. The batteries themselves hold their charge nicely and I get approximately 8.5 minutes of flight time.

These were exact replacements for the batteries in both my Syma S107G helicopters. Fit perfectly and now they fly for much longer periods of time. Cutting out the old ones and soldering in these was not too difficult but I'm fairly handy and had a soldering gun, solder, snipers and a small screwdriver. The batteries seem to be the right capacity as listed and hold a charge so far. Happy with the purchase!

The new batteries once soldered in, lasted 1 take off, 4 sec of flying and then could not get off the ground again, these are JUNK used batteries

The battery on my helicopter would not hold enough charge to use it for even a minute. I was going to toss it but instead purchased these batteries. Replacement took about 5 minutes and now my helicopter is working great again. I bought the 2 pack but after replacing the old battery it appears 1 would have been fine.

Worked just fine, but it was supposed to be a two pack and I received one.
