An In-depth Understanding of 50C High Discharge Rate LiFePO4 Batteries
Lithium iron phosphate (LiFePO4) batteries boast a range of unique advantages, including high energy density, long cycle life, low self-discharge rate, no memory effect, high safety, and environmental friendliness. These batteries are widely used in UPS, energy storage systems, AGVs, starter power supplies, and emergency power systems.
With the rapid development of the new energy sector in recent years, numerous companies have entered the market, bringing new application opportunities for LiFePO4 batteries as well as new challenges, especially in scenarios requiring high power output and fast charging. To address these issues, PLB Battery has introduced the 50C high discharge rate LiFePO4 battery (IFR26650-25B), achieving high power output and rapid charging capabilities. Let’s delve into the features of this high-rate battery.
Before exploring high-rate batteries, it’s essential to understand what “rate” means. The rate, denoted by the letter “C”, indicates the battery’s charge and discharge performance. For example, the nominal rated capacity of the IFR26650-25B battery is 2500mAh (1C), 1250mAh would be 0.5C, and 125Ah (125,000mAh) would be 50C. The higher the C-rate, the higher the current the battery can discharge. Therefore, a high-rate battery is one that can discharge a large current.
The PLB 50C high discharge rate LiFePO4 battery (IFR26650-25B) can achieve an instantaneous 50C discharge and a continuous 30C discharge, with a 5C charge rate. This technological breakthrough overcomes the cylindrical LiFePO4 battery industry’s limitations, opening up endless possibilities for cylindrical LiFePO4 battery applications. Here are the detailed specifications of the battery:
