A multi chemistry charger with firmware that is upgradable to accommodate changing battery technology is a better way to go. CellPro (and other knockoffs) has several chargers that will safely and accurately charge LiFePO4 batteries among many others with one charger.

I have used a Cellpro multi 4s charger to charge my Shorai lithium iron battery which does not have a battery management system for quite a while. It will also charge a lead acid, nimh, nicad, lipo and others.

You will be able to set the charge rate, monitor the health of the cells, balance the cells (still important for a LiFePO4).
