Production EVE 50PL vs old EVE 50PL

In this video, I share a surprise comparison test between the new production EVE 50PL cells and the pre-production 50PL cells with the EVE logo.Both cells were tested under the same conditions to show real differences in: Voltage sag Power delivery Temperature behavior Capacity under load This test helps clarify what actually changed between pre-production and mass production and why it matters for real-world high-current applications. All data shown comes from controlled 40A testing. If you are building high-current packs or selecting cells based on real performance, this comparison will give you useful insight.
