Lifepo4 charging power supply issues

[ericfx1984]

I have been trying to find a good option for charging lifepo4 batteries...

So far I have tried three separate adjustable 12 volt power supplies.. 36 amp power supply did a fine job running at 13.6v @ 36 amp charging a huge 4p4s battery for about 24 hours

I was not able to adjust either of the 50 amp power supplies past 12.4v

I'd like to be able to charge at 100 amps...

Any suggestions on a cheap bench power supply or something like this?

How low will the 50a adjust? Set each to 7.00 volts and put them in series.

I would generally recommend MeanWell but not exactly cheap.

Powermax is adjustable but comes in at $260 for 100 amps.
