Advantages of lithium iron phosphate batteries
- Good safety performance
Safety comes from the stability of the cathode material and reliable safety design. The lithium iron phosphate battery pack has undergone strict safety tests and will not explode even in severe collisions.
- Long cycle life
The 1C cycle life of lithium iron phosphate batteries generally reaches 2,000 times, or even more than 3,500 times, while the energy storage market requires more than 4,000-5,000 times, which is higher than other types of lithium batteries.
- Good high temperature performance
The thermal peak value of lithium iron phosphate battery can reach 350~500℃, the working temperature range is wide (-20~+75℃), and 100% capacity can still be released under high temperature (60℃).
- fast charging
Using a special charger, 1.5C charging for 40 minutes can fully charge the battery.
- environmentally friendly
The lithium iron phosphate battery is green, non-toxic, non-polluting, has a wide range of raw material sources and is cheap.
LiFePO4 battery voltage and capacity
LiFePO4 battery voltage
The nominal voltage of a single lithium iron phosphate battery is 3.2V, the charging voltage is 3.6V, and the discharge cut-off voltage is 2.0V. The lithium iron phosphate battery pack achieves the voltage required by the device through the series combination of the cells, the battery pack voltage = N* the number of series. Commonly used lithium iron phosphate battery pack voltages are as follows:
- 12V lithium iron phosphate battery
- 24V lithium iron phosphate battery
- 36V lithium iron phosphate battery
- 48V lithium iron phosphate battery
Lithium iron phosphate battery capacity
The capacity of the lithium iron phosphate battery pack is determined according to the capacity and quantity of the cells connected in parallel. Generally, it is determined according to the specific requirements of the electrical equipment. The more lithium iron phosphate cells are connected in parallel, the greater the capacity.
Common lithium iron phosphate battery pack capacities are 10ah, 20ah, 40ah, 50ah, 100ah, 200ah, 400ah, etc.
