A better test might be a lower amp draw for a longer time period. Maybe use a window fan. Heat producing appliances drain any battery quickly. Thank you for the video!

I purchased a generic ego battery via ebay. The weight of the battery was about half that of the genuine battery. I sent it back. Clearly it was not rated correctly.

I have often thought buy dtk batteries. But my concern is the chances of fires. What are the risk of fires associated with after market batteries like dtk?

“Konking out”? Sounds like Brit-speak to me… The early batteries were great, but somewhere along the way, they have started sourcing cheaper cells. I have the Z6 and watch my batteries like a hawk. I’m afraid they will die before the 5 year warranty expires and I will be claiming, if that happens!

Names seem to keep changing. "DTK"? SunMily seems gone? Anyway, thx as "$100 vs 2-300" dollar batteries still seem to prove out despite falling short of claimed amp hours (3.5 vs 5). At some point, hopefully more people gut these and reach for those Tesla cells. 18650, 2170, to keep their stuff alive. I'm still dumping electric-(insert tool here) because I don't tear down, yet, and rebuild.
