In this video I test and tear down the Eco-worthy 12V 314Ah battery, a budget option at $450 or $112 per kWh. I run a capacity test, run a 200 amps continuous current, check the overcurrent protection, and open it up to see the cells and BMS inside.

The battery actually delivered 330 amp hours, about 5% more than its rating, and the build quality surprised me for the price. But I also found three issues you should know about before buying, including a safety concern with the app. I sent all of this to EcoWorthy, and their response is at the end of the video.
