Advice on charging LiFePO4 batteries with a bench power supply.
My power supply is actually 3A. If I set the voltage to 55V and the current limit to max, it will deliver 3A to the battery in CC mode and then automatically switch to CV mode at 55V when the current draw becomes less than 3A. This sounds like how a lithium charger works. ... Charging Deep Cycle Battery with Jackery Panels

High-power battery charging using a 3-phase to DC "benchtop" power supply
$begingroup$ That''s a power supply. Not a battery charger. It will never care about the battery being too empty or too full, or too cold or too hot. So it is lacking all safety mechanisms you would expect from a battery charger. It will also never stop charging the battery when it is full but continues float charge until you disconnect it.

CC/CV stands for constant current/constant voltage. This means the battery starts charging at constant current (e.g. 500 mA) then once the upper voltage limit is reached (e.g. 4.2 V) the circuit switches to a constant voltage source (e.g. at 4.2 V) and the current trickles down from 500 mA to near zero.
