For some cell experiments I am looking for an acceptable priced constant power charger for a single LiFePO4 cell.
Cell datasheet states: 0.5P 502.4W @3.65V
Thus around 3V the charger should be able to supply 502.4/3=167.46 amps (I rounded this up to 170A).
I can live with CC 502.4W/3.65V=137.6A.
Any suggestions for a reasonable priced high current single LFP cell charging solution supplying 137.6Aor modbus/serial programmable to mimic a CW-mode and 3.66V OVP?

- A bench/desktop power supply was my first though. Those lack a "CW" (constant power) mode, or when they have a CW-mode, these programmable power supplies are so expensive that the suppliers don't even dare to mention the price.
- An industrial power supply was my second though. Most (f.e. TDK SWS1000L-3) have a configurable voltage, but no constant power mode. This PSU is expected to touch OCP within seconds.
- Then I stumbled upon a programmable AC-DC power supply, that can be put in parallel, like a TDK HWS3000G-24 or XP Power HPF3K0PS24. Those power supplies are still € 2000 for 2 pcs.
