For 48V150ah 48V5A lithium battery charger, it is not recommended to use fast charging. Fast charging can only charge 80% and will not be fully charged.
The number of charge and discharge cycles of lead acid batteries is about 350, the number of charge and discharge cycles of ternary lithium batteries is about 800 and the number of charge and discharge cycles of lithium iron phosphate batteries is about 2000. The storage temperature of lithium iron phosphate battery is -10~35℃, and the discharge operating temperature of the battery lithium iron phosphate is -20 ~ 65 ℃.
Before buying a lithium battery, first check whether the battery cells it uses are grade A. Second, look for a lithium battery. lithium battery produced by a major manufacturer, mature production technology, after-sales serviceguaranteed and the market reference price of lithium batteries is 1,250 yuan/KW.H. If you have to travel long distances, it is best to install a range extender.
The specific selection of battery charging current for 150AH is as follows:
1. The battery typically retains more than 20% power and chemical conversion. the efficiency when charging the battery is about 50%, to fully charge the battery requires 150%*80% increase in electricity.
2. The optimal charging current of the battery is 10% of its capacity, or 10A. Charging time requires 150%*80%/10%=12 hours, plus approximately 1 additional hour. charging in stages.
3. In order to respect people's working and rest time, in the design, a charging current of 13% of the capacity is generally used, that is, 13A. at least 150%*80%/13 %=9.2 hours, plusAdditional time for segmented charging is approximately 1 hour.
4. Fast charging, generally charge with a current of 20% of the battery capacity, or 20A, and the charging time is 150%*80%/20%=6 hours. Charging with a larger current will shorten the charging time, but it will damage the battery, so use it with caution.
