Hi,
A while back I purchased:
https://www.adafruit.com/products/259
It worked fine for a few days then it went kaput. When I try and charge one of the LiPo batteries supplied here, both the charging and done LEDs do not turn on. I'm not getting any voltage out of the connectors and don't know what's wrong.
Thanks for the help anyone.

What are you using as a power source? Have you checked the voltage from that?

I'm just using direct from the USB connection. A 5v connection from my computer or wall adapter.

What about the power LED - does that illuminate when you plug it in?

The power LED is just dandy. The rest of the PC board on the other hand...

My Dad purchased it for me the summer of 2011. I'll try and find my Dad's account info if need be.

Re: USB LiIon/LiPoly charger Woes
Are there any schematics about this board? I'm fairly handy with SMT components.
