Godox AD600B

Edit My Images
I have the Godox AD600B, I recently purchased the hand held Flash extension (ADH600B) so that I can be more mobile with my strobe light. In the middle of a shoot, I had my strobe light on automatic light level three When it shut off. I went to cut it back on but it would not come on, I thought maybe the battery was dead, even though I knew I charged it the night before. After charging it again it still will not come on. I don’t see any signs that the battery is the issue, the battery is charging fully and continues to light up all battery levels. I continue to press the power button on my strobe light but it will not come on. Anybody had these issues? I just got this brand new light
