Hey there! As a supplier of LiFePO4 house battery storage, I often get asked about the discharging voltage of these batteries. So, I thought I'd break it down for you in this blog post.
First off, let's talk a bit about LiFePO4 batteries. Lithium iron phosphate (LiFePO4) batteries are a type of rechargeable battery that's becoming increasingly popular for home energy storage. They've got a bunch of advantages over other battery types, like longer lifespan, better thermal stability, and a higher charge/discharge efficiency.
Now, the discharging voltage of a LiFePO4 battery isn't a fixed number. It changes depending on a few factors, mainly the state of charge (SOC) of the battery. When a LiFePO4 battery is fully charged, its voltage is around 3.65 - 3.7 volts per cell. But as it discharges, the voltage gradually drops.
Typically, the nominal voltage of a single LiFePO4 cell is 3.2 volts. That's the voltage you'll usually see when the battery is at around 50% state of charge. As the battery continues to discharge, the voltage will keep dropping. When it reaches about 2.5 - 2.7 volts per cell, that's considered the end - of - discharge voltage. Going below this voltage can cause damage to the battery and reduce its overall lifespan.
In a home battery storage system, LiFePO4 cells are usually connected in series to achieve a higher voltage. For example, a 48 - volt LiFePO4 battery pack might be made up of 15 or 16 cells connected in series. So, when the battery is fully charged, the total voltage of the 48 - volt pack would be around 54.75 - 59.2 volts (3.65 - 3.7 volts per cell x 15 or 16 cells). And when it's at the end - of - discharge, the voltage would be around 37.5 - 43.2 volts (2.5 - 2.7 volts per cell x 15 or 16 cells).
Why does this matter for your home energy storage? Well, understanding the discharging voltage is crucial for proper system design and operation. Your home appliances and devices are designed to work within a certain voltage range. If the battery voltage is too high or too low, it can lead to problems with your equipment. For instance, if the voltage is too low, your appliances might not function properly or might even get damaged over time.


Also, the discharging voltage affects how much energy you can actually use from the battery. You don't want to discharge the battery all the way to the end - of - discharge voltage every time, because that can wear out the battery faster. So, you need to set up your system to stop discharging at a safe voltage level, usually a bit above the end - of - discharge voltage.
Let me give you an example. Say you have a 5KWh 48V 100AH Server Rack Lithium Battery. You'll want to make sure that the system is configured to stop discharging when the voltage reaches a level that won't harm the battery. This way, you can get the most out of your battery in terms of its lifespan and the amount of energy it can provide over time.
Another thing to keep in mind is that temperature can also affect the discharging voltage of LiFePO4 batteries. In colder temperatures, the battery's internal resistance increases, which means the voltage will drop more quickly during discharge. On the other hand, in warmer temperatures, the battery can deliver a more stable voltage, but high temperatures can also reduce the battery's lifespan if they're sustained for too long.
