After the lithium battery pack is discharged
While lithium batteries with BMS protection can safely undergo full discharge or charge temporarily, prolonged storage at 0% is dangerous because the BMS continues drawing a small standby current, which may eventually drain cells to 0V and cause permanent damage - occasional full discharges are acceptable but should be recharged within 24 hours.
FAQs about After the lithium battery pack is discharged
What happens when a lithium battery is fully discharged?
When lithium batteries are fully discharged, the chemical reactions inside the battery can change, directly affecting its capacity. For example, if a 21700 battery is over-discharged, its usable energy will be significantly reduced, leading to shorter usage time, and it may not be able to fully recharge to its original capacity.
