ok i am building an arduino clone and am wanting to have a built-in charger for the li-ion bat i got . so i was wondering if anyone knows how i moght be able to get this fast charger to work because im having a lil trouble figuring out the datasheet .

so got 2 of these BQ2054 data sheet, product information and support | TI.com and i 1 of these Battery - SparkFun Electronics so if i end up burning up the first charger i still got an extra :wink: and i have a few old cell phone batts laying around i wanna try to use as well. so any help is appreciated :sunglasses:

I probably can't help (I'm not into Li-ion batteries), but the link

isn't very helpful as it shows a bit long list of stuff.
You might identify the specific part you've got so folks can figure out what you are asking.

yea i wasnt realy paying attention this morning i had a bunch of stupid crap going on i even messed up the title ;D ::slight_smile: but o well any way heres what i have Lithium Ion Battery - 1Ah - PRT-13813 - SparkFun Electronics and i have a bunch of old 800mah - 1000mah cell batts i was wanting to add to my project to make it last longer. all i am trying to do is figure out how to charge my battires with that charger ic so i can make a small encloser for my arduino and battires and have a usb port on the outside to upload sketches and charge when needed. i just cant figure out how to wire this ic . :o kinda lost in tha data sheet.
