Charge LiPo 3.7 240mAh with 3v? Answered

I have been told that I need to use a charging controller to charge a LiPo 3.7 240mAh with 3v. I have searched and cannot find one. Any help? It needs to be very small as well.



You know these questions could have stayed in your original post.

First of all you have not been told you can charge a 3.7V LiPo on 3V. You've been told it would require extra circuitry to charge the battery on 3V and you've also been told you need a charge controller to monitor the charging of the battery. You need to look for a charge controller compatible with your battery. Then based on that controller find a suitable power source to charge the battery with. In your case you'll want a solar panel that can offer more than the minimal voltage the controller is looking for. Since the controller will work with a range of voltage.
