Adjustable LiPo Charger

Hello,

I have connected a [18650 battery WITHOUT powering the [adjustable LiPo charger (14380) with the selector @500mA and to my surprise I smell something.

I tried to disconnected the battery (I was not too fast, maybe 30 seconds) and I think the resistors where hot.

Can I hook on this charger big capacity batteries to charge? The capacity of battery was 3400mAh

Now the RED led stays open when powerd via USB, but it does not charge.

I made something wrong? I have to power the device and THEN hook the battery? Thank you.](https://www.sparkfun.com/products/14380)](KeepPower 3400mAh li ion protected 18650 battery NCR18650B)

Can you share pictures of how you attached the battery and the board itself?

Sorry for the delayed answer.

That was awfull, I trusted the connector, it’s reversed!

I checked with the polymeter the connectors of LiPo charger. Please add + and - icons to the connector.

Thank you for your fast answer.
