3.7v Lipo, charge with 5v charger OK?

Hello,

I want to charge a 3.7v LIPO battery. (1800mAh)

And I have the SparkFun 3.3v/5v LIPO charger board.

Which one will work best or work at all?

I just want to do it once, I have a 3.7v charger on the way.

Say I use the 5v setting, what will happen or why will it be bad,

or why won’t it work?

Thanks.

Hi stone.

What specific board do you have? Can you give me the part number for the board you have or better yet, send a picture?

Thanks for the response.
