Will it damage it?
If a mppt is 60 to 80 amps and the battery connected is 50 amp charging max will that damage the battery?

Depends.
Is that a recommended or a hard limit?
If recommended, it will likely harm it resulting in reduced cycle life. It may not be by a meaningful amount.
If a hard limit like by a BMS, the BMS will prevent charging at > 50A by cutting it off... not regulating it to 50A but PREVENTING any charge at all - taking it to 0A.

So you have to consider the batteries max charging amp when buying a all in one? On top of the voc and min max amp range of mppt?

I'm looking at this one

Solar Joules are catch and release
I’d get a battery rated for higher charge current, or put another one in parallel or see if there are settings on your charge controller to limit the current.

You would need to confirm that the AIO will not send in too much, or that the AIO has a setting to limit charge current
Usually if the AIO can communicate it would have charge current limiting (because that’s one of the parameters sent back by the battery).

Yes. You must consider the limitations of all hardware in the system.
This should be a huge Banner at the Top of the Forum.
Yes I have failed to always do it and regretted it.

Yep... I put 135Voc on a 150V controller and realized it before it got too cold. So at least the regret was just financial as I upgraded to a 250V controller.
Double your battery and you should be fine. If you are planning 12v then buy 2 and wire in parallel. You can now charge up to 100 amp max. Also, i know that victron mppt allow you to limit the max charging amp. You can set the mppt to 50 amp max.
