i was testing my brushed motors with the common mobile  battery! does any one have an idea for connecting the wires to the small metallic strips of the battery!

Soldering is the best possible way to connect the motor to the battery. solder it directly with a switch to on/off the motor

soldering the wire leads to a mobile battery can be pretty hard...because solder sticks on ONLY if the surface is clean and hot..
good luck !

is it not too risky to solder the metallic plates they are too tiny! if we manage to solder it the how r we going to charge it?

exactly. Dont you think it would be better to buy a decent Lithium Polymer Batt and use it instead ?
you can solder what ever you want to it

There are so many other alternatives available. What are you trying to run on that battery?

have a spare battery lying around so taught of using it! its pretty small and weighs less!

Cut out some metal strips and attach it to the battery terminals and the battery like a clip, running along the length of the battery. You can solder anything you want to it

I just read what I typed and realized that its confusing as hell even to me and I wrote it! So here's a doodle on paint:



I'm sure you know that the exposed sides of the metal strips have to be insulated. But even with all that, it will still be super light. Plus you can cut the strips to size, solder the wires and then attach it to the battery. Ensure that the tips are bent inward so that it always maintains a strong contact with the battery terminals.

Of course, you can always practice soldering and save yourself all this trouble by soldering directly to the battery contacts

Try using liquid flux, it makes soldering easy, quick and clean (even on unclean surfaces). It's not that hard soldering on mobile battery terminals if you have a pointed tip mini soldering iron (I've tried on a similar surface before).

tassem your idea is best as i have tried it , soldering is not an option , as we have to charge it again , but if you have a seprate charger u can solder it , just pealout that plastic cover you will find a circut and battery inside , but dont forget to insulate it otherwise you will have a burning bomb.

Liquid flux is often acid based and is best avoided for electronics . A good flux cored solder is all you need.

Thanks sir, I didn't know that! Liquid flux has helped me a lot and I haven't yet noticed any bad effects because of the 'acid' content you mention. Are there non-acid based liquid fluxes too? How to identify them?

As I have said, you DON'T need flux actually if you have a good flux cored solder, AND THE JOINT IS CLEAN! Scrape the metal lightly with fine emery or a knife so that it appears shiny. First "tin" the contact and the wire. Then solder.  One good brand of solder is "JOINT" (a rather unimaginative name).  Acid fluxes, may cause corrosion over time. If you still feel the need for flux use the paste form. I think "Quickfix" is still available.

A good joint (not the "weed") requires clean surfaces, a good iron and bit, and some skill that comes from practice.

I do not have any experience in connecting mobile battery but in a science exhibition a boy was demonstrating magnetic levitation. He had fixed a pusher prop to the model for the forward thrust.
The power was drawn from a mobile battery. He had a simple solution to connect mobile battery. two 2mm plates were inserted between the battery and the mobile electrodes with some rubber pieces in between. The plates were soldered to wires. Simple!!!! Is it not?
