Hi dudes,
I'm working with arduino mega2560 and I have a ion lithium battery of 3.7 V. It works perfectly until battery is discharged.
So, I have a doubt, how can I do to charge the battery through the arduino??
I'd like to use it autonomously.
Now, I connect the battery to arduino by external reference pins.

Generally, get a battery charge control chip. These are available as shield from several sources.

Hi,
Thanks!!
I'd expect I could make my own system to charge it. I'll have to look for another solution before get one of those chips.
Thanks again.
Regards.
I used MAX1811 in a remote control to charge 1000mAH LiPo battery from 5V source, such as USB.
Only needs a couple of external parts.

Thanks!!
I'm going to try it.
Also I'd like to use a mini-usb to connect the arduino to the PC, so I can read the values and charge the battery when it is discharged because the PC was switched off.
Regards!!
