When the charging cycle exceeds 300, 500, and 1000 times, the charging voltage of the BMS flex cable will decrease.
After the voltage decreases, even if you replace it with a new batery cell, you cannot add more power capacity. The standard limitvoltage of the lP11/12 series is 4.45V, but it drops to a maximum of 4.34V.
When the original BMS flex charging cycle is more than 300 times, the capacity loss is about 5% even if you use a new battery cell.
When the original BMS flex charging cycle is more than 800 times, the capacity loss is about 8% even if you use a new battery cell.
When the original BMS flex charging cycle is more than 1000 times, the capacity loss is about 13% even if you use a new battery cell.
Therefore, even if you replace a new cell with a standard capacity, the user can feel the same capacity or battery life as before the replacement, so stellarXcell Ultra cells have a 10% higher capacity than standard capacity cells, eliminating the capacity that cannot be released due to forced voltage reduction. So the customer can feel good about the new battery functon.
