Can anyone tell me how many amp hours these batteries have? I recently was given 24 of them that I would like to use in a  48 volt Bank.

    They appear to be upwards of 150 Ah.  If you use all of them in 6 strings don't expect a long life, for two reasons. Uneven charging of parallel strings and these aren't designed as deep cycle batteries.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric,  460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

    And how much energy they store:

    • 155 AH * 12 volts = 1,860 Watt*Hours per battery
    What do you want to use the battery bank (plus AC inverter?) to run? And how do you plan on charging them?

    Details matter here.
