Seamless and much more capacity than advertised
I had this battery backup setup on my BGW620 and lost power for over 8 hours during recent ice storm, but, great news, I never lost internet. We had four in the house on tablets, computers, streaming and never lost internet connectivity. I had one TV and a FireTV on a different and much larger UPS box, that only last about 2 hours. This thing is outstanding, so small but kept the Internet up and outlasted the UPS which surprised me.
