MKR ZERO works from USB cable, however, when I connecting LIPO 3.7v 1000mAh battery it doesn't work.
When I connected USB and Lipo, charging light is on, which indicates that battery is in charging mode, however after 4 hours of charging, it is still on.

I uploaded simple example "LED Blink" no luck and tried to run on battery only, no luck. Is anyone can direct me what I am doing wrong? Thanks!

I figured out... I swap the polarity on the lipo battery.
