Hello,
I have a Circuit Playground Bluefruit, and I am doing the project No-solder LED Disco Tie:
https://learn.adafruit.com/no-solder-ci ... -disco-tie
The project powers up just fine with USB cable, but plugging in a battery does nothing. I just got a new battery today, charged it and plugged it in.
Is there something I'm missing here? Thanks.

Please post a clear picture of the connector end of the battery cable. Where did you get the battery?

Re: Circuit Playground Bluefruit, does not turn on with battery
The Amazon listing specifies the battery has a JST-PH2.0 connector.

Bluefruit specs don't say what type of battery connector it is, but the suggested battery for the project says it is JST-PH.

Measured the battery voltage at 4.11 volts.

Thanks. That battery has the wrong polarity for Adafruit boards.

Dang, you're right. That probably means I can't flip the wires because then it won't charge.

Re: Circuit Playground Bluefruit, does not turn on with battery
As it seems the charger matches its polarity, you are correct. Fortunately it doesn't sound like the CPB was damaged in the process.
You could get something like https://www.adafruit.com/product/1131 and reverse the wiring in one end, for use with the charger. Just be sure to label it clearly!
