The function of the iron-lithium battery protection board ①The protection board has the function of overcharging voltage protection. The maximum limit voltage of a single lithium battery is set to 4.2V. When the charging voltage reaches this value, the circuit board limits charging and has individual cells The battery indicator shows. ②The protection board has an overcurrent protection function. When the working current exceeds the rated value, the lithium battery protection board sends a signal to stop the lithium battery pack. ③The protection board has a short-circuit protection function. When the external short circuit is caused by various reasons, the lithium battery protection board will protect the lithium battery pack, and be wary of damage to the lithium battery pack. ④The protection board has a temperature protection function. When the working temperature of the battery exceeds the rated value, the work of the lithium battery pack is stopped through the circuit board to avoid accidents, thereby protecting the battery pack and the user.
