10A will charge it fine. As mentioned, just make sure CV is +/- 14 to 14.4 volts, and terminates when the battery voltage reaches the charge voltage. No float or equalization. If you're going to float it then 13.4 CV. Or put it on a timer and terminate it.
Just understand if you use 80 amp hours out of the battery it may take ten or fifteen hours to recharge.
I really like the MeanWell chargers, but Victron has their IP line that is very good as well. A 25A meanwell charger is about $125, the Victrons are a little more. The BT interface on victron stuff is pretty cool.
Most 'lithium' compatible chargers will try to charge to 14.6 volts, and most lifepo4 batteries with a BMS will terminate charging for cell over-voltage. Which is not a very good way to manage charging.
