How to Properly Charge Lithium Iron Phosphate (LiFePO4) Batteries
Standard Charging Rate: Recommended at 0.5C to 1C, where “1C” means charging at a rate that would fully charge the battery in one hour. Moderate Rates: For optimal
Lithium iron phosphate batteries can be charged in as fast as 1 hour. We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the data sheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.
During the charging process, the output voltage of the charging power source remains constant. As the state of charge of the lithium-ion phosphate battery pack changes, the charging current is automatically adjusted. Suppose the specified voltage constant value is appropriate.
The charging current for these batteries usually ranges from 0.5C to 1C, where C represents the battery's capacity rating. Lithium iron phosphate batteries represent a safer alternative with enhanced thermal stability and longer cycle life.
It is recommended to use the CCCV charging method for charging lithium iron phosphate battery packs, that is, constant current first and then constant voltage. The constant current recommendation is 0.3C. The constant voltage recommendation is 3.65V. Are LFP batteries and lithium-ion battery chargers the same?
