DualSense Battery Odyssey - Ep. 5: 14.5Wh Claim vs Reality – Hisewen 3980mAh Exposed

DualSense Battery Odyssey Episode 5: Testing the Hisewen 3980mAh (claimed 14.53Wh) replacement battery.

Full teardown, protection circuit analysis (spoiler: no thermistor), and why this one isn't worth buying. If you're upgrading your PS5 DualSense controller, watch before you buy!
