I Bought 2 Broken EcoFlow Delta Max Units... Was It a Mistake?

I got my hands on not one, but two EcoFlow Delta Max units from eBay for a fraction of the cost—only $199 each! One unit has a faulty AC port that throws an "AC overload" error , and the other greets me with the ominous "red battery of doom".

Join me as I tear down these powerful, 50-pound beasts to uncover what's really going on inside. I'll be digging into the circuitry, checking the battery packs, and attempting to diagnose the core issues behind these failures. The goal is to see if I can combine parts from both units to salvage at least one working power station.
Will I be able to bring one or both of these units back to life? Or will this be a lesson in why some deals are too good to be true?
Watch now to find out if this repair mission is a success!
