DC to DC charger charging a Lithium 100amp 12volt

Is it OK to charge a lif04 lithium 100amp 12v with my DCDC AGM charger 25 amp Charges to 14.4v then keeps at 13.8v This is the brand https://www.projecta.com.au/dual-battery-charger-idc25
Thanks in advance

My understanding of the collective wisdom of the net is that LiFePo4 batteries don't need or want a float voltage, and that a float voltage of 13.8 V is high enough to be detrimental. The instruction manual for the charger says on the second page, in all caps: "FOR CHARGING 12 VOLT LEAD ACID BATTERIES ONLY." Nowhere does the instruction manual even mention the word "lithium".

Why didn't they claim they can also charge LiFePo4 batteries? You can ask them yourself via the toll-free technical support number on the contact us tab of the page you linked.

Despite all that, in an emergency could I use their charger to charge a 12V 100 Ah LiFePo4 battery, for instance by:

1. Continually monitoring the battery voltage, and
2. Immediately disconnecting the charger once the voltage got near 14V?

Why yes, I could in theory. But, I wouldn't want to make a habit of it.

13V 13.5V for a 12V battery is generally considered safe if the charger can't turn off, or if it's a situation like a DC coupled inverter where the charger should always be available to supply current to the inverter.

*edit*
13V is an error, this should be 13.5V

Gnubie, you touched on something I couldn't quite figure out -- how to make an online UPS using a LiFePo4 battery. To avoid hijacking this thread, I'll open another for that.

I have bought a new renogy dcdc 50 amp charger
