Can I simply replace my lead batteries for lifepo4

[Julien]

I have a small, one panel, solar setup running an off-grid irrigation system in rural France. For the past few years this system has utilised two 12v leisure batteries to run a couple of 24v dc pumps. The batteries are reaching the end of their life so I decided to upgrade to lifepo4, and have managed to pick up a second-hand Pylontech UP2500 24v unit. My question, can I simply swap out the old lead batteries for the Pylontech battery. I am using a Renogy Rover MPPT charge controller.

Thanks

Jules

Does the rover have adjustable voltage settings, they should be adjusted a bit for lifepo4 usually.

Generally yes a direct swap.
Best if the equalization can be disabled and possibly adjust the charging and float voltages to meet the battery specifications.

Also may want to set the low voltage shutdown for lifepo4
