I thought you were using a separate charger? You posted a link to something that I thought you were planning to use.

But if you are trying to charge with just the Pico, you do need that jumper shorted. You actually need:
```
function stop() {
  digitalRead(B0);
}
```
As setting to 1 is 3.3v, which won't fully turn the FET off. There is a tutorial on that here: http://www.espruino.com/Pico+FET+Output

... but I wouldn't recommend doing this - maybe with NiMH batteries, but for LiPos they can get very unhappy if overcharged. Much nicer to just use a special charger IC -
the new shim collection board has outlines for LiPo charger ICs on a lot of the shims too.
