I have dozens of RC battery chargers, and use them extensively on a near daily basis; however, many have limitations of 5, 6 and 10A charging, and their cost is comparable to a 30V/10A adjustable PS with none of the versatility for the task at hand.
If you already have an RC charger capable of LFP cell charging, great. If not, investing in one is less productive than buying the typical 30V/10A adjustable power supply.
