Batteries arrived on time and in excellent condition. Adding the batteries to my existing system was easy. Very pleased with the Bluetti product. My only recommendation is they address their product support. I’ve invested significantly in Bluetti and I do have concerns about support if and when I need it. It’s actually a series concern I have.
I have the AC500 and 3 B300s and very satisfied. Actually got to try it out in a power outage we had for 2 days. Worked flawlessly and as advertised. Going to expand in the near future.
