I bought this about a month ago. I got it so I could run the Wave 3 from DC power on my Bluetti power station with 3 chungas batteries. I'd actually prefer to have that ability without having to buy another battery. The battery is working. It has a cool mounting system. You can set it to charge and discharge within the max limits to extend lifetime. I don't like that I have to disconnect AC shore power, which I normally have, from the Wave 3 to get the battery to turn off. I want to leave it in position under the Wave 3, which will normally run off AC, then turn the battery on to charge when I know I'm going to need it. Finally, the website is irritating because its easy to find the product, but there are no links to the docs on the product page, you have to go into a generic manuals section and search there.

This one kilowatt hour capacity add-on battery can charge from a c through the AC unit or can charge through solar input. It's a lipo battery so it has a much longer lifespan than the NCM batteries and it snaps into the bottom of the Wave 3 so it makes for a nice base. Good for hours of continuous use.
