❌ Error 3: Installation of a battery with a different capacity
Some "masters" put a larger battery (e.g., 6,000 mAh instead of 5,000) in the hope of increasing the time, which actually leads to a faulty charge controller and rapid degradation. Solution: take a battery with exactly the same capacity as the original.
