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!!
