Syma S107 How to replace repair battery 

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

Making use of the ru-vid.comUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

An able man always makes difficult/complex/intricate jobs look very easy. Respect Sergio.

There are many ways to do this. This is how I do it. If your soldering skills and hardware are good then the overheating problem is not gonna be an issue. You should use the procedure that you feel most comfortable with. Please restrain yourself from making these kind of comments in the future. There are many ways to "peal a banana". BTW that heli in this demo is working fine. Regards

I think you are going about this the hard way. Why not just clip the wires from the old battery and solder the new battery onto the clipped batteries and used heat shrink tubbing to isolate them. No need to dismantle the whole helicopter. Check out my youtube videos....I build guitar pedals.

thank you i found one and ordered it! very much appreciated :) subscribed!

but he is showing another way of doing it that's good for educational purposes for youtube :)

Lets go the hardest most time consuming route! The easy way is just to solder the leads to the new battery after some simple snipping!

what battery did you use

My stock battery got bad so i ordered a 240 mah lipo. cut the wires nd taped the new battery bt still there is no power in the heli and it charges in 10 mins( i know dat it should take much more time than that ) ....plz help.

Thank you for your comments. This heli is not mine. I did this for a friend of mine, so i can´t realy tell for how long the battery lasts but he told me that, in fact, it lasts longer than the original one. About you second question the answer is yes. You can cut the wires and solder them together instead of unsoldering the battery from the main board. Cheers

Well done, how long does the heli fly with the 240mah lipo ? thank you for this nice introduction i will change my lipo soon ... Is it possible to cut the cable und put this together with the new lipo ? best wishes ...

That's one way to go. I just like to do things the difficult way. :) Thanks for the comment.

@LMT4Y10R Thanks for the comment. In fact it extends the flight time and the weight seems to have no effect on it. It's a good upgrade.

Great vid, I'm thinking of changing my battery from 150mah to 240mah like u. But the only thing that bothers me is the difference in weight and if it flies the same. How did yours fly after the swap and did u get any more flying time from that battery? Cheers, Lee

Isn't it a good idea to connect the negative battery terminal first?

Thank you so much!

What temp was used on the saucer and what wire type and grade used?

my syma s111g every no charging, is the battery?

Thanks you for answer ! ;)

You are welcome :)

3.7V 240mAh 20C Lipo Just search ebay for Syma S107 battery and you'll find it. Cheers

Como reparo el motor de la cola a veces anda a veces no. solución Gracias de ante mano!

You have to be kidding, right? Why in the world would you disassemble the entire helicopter and solder wires to the mother board, the most heat-sensitive part of the helicopter? If you really want to solder the contacts, at least solder to the battery leads like the other video on this subject shows, with 1/10 the work. Better yet, just cut the wires off the old battery, twist the wires together, cover the connection with tape or glue to insulate it, and forget soldering altogether!

Soddering? you mean SOLDERING it has an L in it.

i was thinking the samething
