These budget server rack batteries from TechEx had absolutely no business being this good. I went in skeptical and came out genuinely impressed — and that almost never happens. In this video I'm doing a full teardown, capacity test, and communication test on the Techex 51.2V 100Ah LiFePO4 server rack batteries to see if they deserve a spot in my upcoming big project.
