Do not charge or discharge the battery deeply, as it may damage the battery. It is common sense to charge it in a timely manner and not to charge it again after running out of battery power. We hope that everyone needs to pay attention to this. For example, energy storage batteries, such as conventional lithium iron phosphate batteries, have a portion of their battery power that cannot be discharged and is always in the battery. It is also necessary to operate at an appropriate temperature when the battery can operate normally. Both overheating and supercooling have an impact on the battery.
