Combining SLA Charging with LiFePo4 BMS Board?

Greek Man

I wonder if this combination is possible for charging 4S LifePO4 batteries

lead-acid Battery Charging Controller with adjustable output

and controlling the charge with this

As far as I can tell this charging board, outputs constant current, with a user settable termination voltage.
(in fact it can "charge" any battery this way)
