@Irene Turner, it depends somewhat on your LiFePO4 manufacturer, as the manufacturer's recommended charge profiles vary pretty significantly from battery to battery; it further depends on the Ah of your bank... if you're using a 50A charger, you should have at least 200Ah of battery bank. Generally speaking, your maximum charge current shouldn't be more than 25% of your bank capacity; that being said, you can set the charge current as well as the absorption and float voltages of your Phoenix, so bottom line is: Yes.

Get your battery manufacturer's recommended charge profiles and use that data to set your Phoenix accordingly.

For LiFePO4 batteries, do not use the built-in preset labelled "Li-ion." Doing so, without modifying the settings in Expert mode, will result in temperature compensation remaining active, and the low temperature cut-off being disabled. The preset float voltage (13.80volts) is also too high for LiFePO4 batteries. Instead, use "Select preset" and choose "Lithium Iron Phosphate (LiFePO4)" from the drop-down menu, which will give you reasonable settings for LiFePO4 batteries, then make adjustments if desired in Expert mode.

I can see where this could cause mis-selection by users who don't understand the distinction between Li-ion and LIFePO4 batteries.
