Solar panels cannot directly charge lithium-iron phosphate batteries. Because the voltage of solar panels is unstable, they cannot directly charge lithium-iron phosphate batteries. A voltage stabilizing circuit and a corresponding lithium iron phosphate battery charging circuit are required to charge it.
Just like your cell phone, you can charge your lithium iron phosphate batteries whenever you want. If you let them drain completely, you won't be able to use them until they get some charge.
The nominal voltage of a lithium iron phosphate battery is 3.2V, and the charging cut-off voltage is 3.6V. The nominal voltage of ordinary lithium batteries is 3.6V, and the charging cut-off voltage is 4.2V. Can I charge LiFePO4 batteries with solar? Solar panels cannot directly charge lithium-iron phosphate batteries.
In fact, I use both of these ways to solar charge my own LiFePO4 batteries. This tutorial will focus on solar charging 12V LiFePO4 batteries, but I'll also share some tips on how you can do it with lithium batteries of different voltages, such as 24V, 36V, and 48V.
The charging method of both batteries is a constant current and then a constant voltage (CCCV), but the constant voltage points are different. The nominal voltage of a lithium iron phosphate battery is 3.2V, and the charging cut-off voltage is 3.6V.
