Lipo rider pro as UPS

I did some tests and discover that the 'Program Mode" of the lipo rider (see on the seedstudio wiki seeedstudio.com/wiki/Lipo_Rider_V1.1) :

doesn’t work with lipo rider pro !
When I only connect the source USB :

  • when the switch is OFF, Raspberry is off !
  • when the switch is ON, red led on raspberry is on, but it doesn’t start : not enough power !! My USB transformer is 5v 2a… it’s enough. I tried an other one, same thing…
    strange.
