This blog is about Over-Discharge/Charge Protection of portable power stations.
Over-Discharge/Charge Protection means that Is your battery protected when the battery is over-charged or over-discharged?
Overcharging causes damage to the battery and creates a safety hazard, including fire danger. A battery protection circuit should be used to prevent this.
Discharging a lithium cell this low is stressful to the cell and reduces cell lifetime. A good battery protection circuit will also provide over-discharge protection.
