Thanks, Dan, that makes sense. If they don't have an internal BMS, that would be very worrisome.</div>

Jay, that sounds like an intriguing idea. So if you're applying a higher voltage, how would you know if it shuts off? </div>

The chemistry is LiFePO4, which is supposed to be the safest lithium chemistry. That being said, I've heard that it's still possible for them to start on fire without a BMS, I don't know on that one.</div>

As far as cycle life, I've heard that there are only two companies that are manufacturing those cells. If that were true, then these should have the same cycle life as any other battery using the Chinese LiFePO4 cells (such as Iron Edison) unless the BMS allows
the cells to get damaged.</div>

"Just sucks seeing people getting screwed." - That's exactly it. Now that he's spent all of this money, I'm hesitant to tell him anything. I don't know if it's a safe setup and I should just tell him to try to use them until they quit working and hope for the
best, or if I need to tell him that they may be an expensive hazard in his basement. I can tell him that they're illegal because they aren't "marked and listed," but the inspectors already signed off on it so the final call is up to him.</div>

Darryl, Sorry, I meant 5 banks of batteries at 4 batteries each (so a total of 500 Ah @48V total). Thanks for the advice, it makes a lot of sense. I'll try to do some testing.</div>
