1 The Brief  introduction of  the charging 

Before we once discussed the safety charging of Battery as below :

Safety Charging Guide for LiFePO₄ Batteries

but we never focus on on the deep charging and deep  discharging of the Battery is good or not for the Battery . But It is very important for us to use the battery better 

2  the Effect of full charging and full discharging to LIFEPO4 Battery and NCM Battery

Before we once introduce the storage energy battery and power battery as below 

LFP Battery and NCM Battery  both of them are chemical storage energy battery . deep charging is different for them 

full charging for the LFP Battery . it is not too bad effect . , It is not too hot ,don’t effect the use lifecycle . but if you full the NCM Battery , you  will find it s very hot , if you always full charge the NCM Battery  .It possibly effect the lifecycle . 

3 Why we need to deep charging and deep discharging it 

now most of the BMS of the battery is Smart . they will calculate the voltage according to the soc . when we full charging the battery . it help the BMS exactly to get the data of the SOC .then the BMS management will be correctly for the battery 

4 when we need to deep charging and deep discharging 

 it will depends on your needs .  for the LFP Battery , if you need to use it everyday . you can deep charge and deep discharge .but if you dont use it everyday ,like just one or two times for one week, pls dont full charge it then put it for long time . because  there is another bad effect . if you full charging and put it away . it will reduce the lifecycle . It is same for the LFP Battery and NCM  Battery 

  Finally do you know how to charge and discharge your battery or now now . 

all of above is just the basic information,  if you have more question , lets study together
