They rarely make sense for small-scale projects. 48V LiFePO4 Battery Voltage Chart VoltageĤ8V is more popular for larger solar systems. They are made by connecting eight 3.2V LiFePO4 cells in series. They are fully charged at 29.2 volts and fully discharged at 20 volts. You can either buy an off-the-shelf 24V battery or pick up two 12V batteries and connect them in series to make a 24V battery bank. 24V LiFePO4 Battery Voltage Chart VoltageĢ4V lithium iron phosphate batteries are another popular option for solar power projects. They are made by connecting four 3.2V LiFePO4 cells in series. They are fully charged at 14.6 volts and fully discharged at 10 volts.

They’re a drop-in replacement for 12V lead acid batteries, and a great upgrade. Here’s a printable version of the above chart:ġ2V 100Ah LiFePO4 batteries are currently some of the most popular for off-grid solar power systems.

12V LiFePO4 Battery Voltage Chart Voltage Consult the manual of your LFP battery for its specific discharge curve and voltage parameters. Note: These charts are all for a single battery at 0A. Here are LiFePO4 battery voltage charts showing state of charge based on voltage for 12V, 24V and 48V batteries - as well as 3.2V LiFePO4 cells.
