I had to use the low voltage repair mode.

This is not a hands off charger.... if the voltage is too low from being drained, you will have to use the "Repair' function on this charger to bring the voltage back up to about 7 or 8 volts before the charge part of this charger will work.
If a 12vdc lead acid battery get down to 7vdc you might as well just trade it in, it will be damaged. Around 10.5vdc is about the minimum.

When I buy a new car/truck battery and add the battery acid for 1.265 gravity batteries, it starts out at 0 volts. I could agree with you for many high amp batteries that after fully charged, if you run dead more than once, they are for the most part, ruined for their new rated capacity.... unless you can desulfate the shorted out lead plates with high-frequency electronic pulses or even chemically.
Meanwhile, Marine batteries have the lead plates much further apart and can withstand this drain down without shorting out, but you do sacrifice amp storage for the same size battery.
The trouble with many cheap digital chargers is they cannot recognize the battery voltage when low voltage and why this OP added a 'Repair' function that sends 12v plus with very low amps to tease the battery back up to the minimum voltage where the regular 2amp charge part will engage. But yes, you are back to the accumulated sulfation from being under or even over charged with other than Marine batteries.
pass.
I don't know that it would hurt anything, but to be safe, I would disconnect this charger on a lithium setup after fully charged.... as unlike lead acid, lithium does not have a float stage. Then again, that is what a good BMS does with solar charging... it shuts off the supply when fully charged.
Personally, I would opt for the higher end Gooloo charger or similar intended for lithium that can use input from a variety of sources including shore charging, solar, even vehicle charging systems. But, if on a budget, I get it.... just don't expect too much for $16.
