Forklift batteries for a solar trailer?
A few months ago, I mentioned a design for a solar trailer, which I'm gathering ideas on, and if I find a decent base for, may start with. A friend of mine has pointed me to a source of recondition...

Don, those batteries do not like to see hundreds of sharp jolts. It would be wise to avoid a buckboard ride. My system trades volts for amps. 12 cells in series, 1625 x 2 amp hours paralleled batteries in a 12-cell string.
Food for thought: Exactly how do you plan to run an equalization on these cells? See if these batteries are "Tar Top" with over the cell connectors.
Let's imagine they are 600 amp hour cells. Five percent of 600 is 30.00 which means you need to configure a 30 ampere current all the way up to 2.666 volts per cell end point. Don't feel picked on. My 3250 cells at 5% = 162 amperes constant current to 2.666 volts per cell. Thank god for a hundred sixteen pound 240 vac transformer. Equalization performed, paired cells, by paired cells.
Large cells emit large amounts of H2S, SO2, and H2SO4 vapor. Vapor dissolves wood, and assaults all but exotic metal. You may avoid grief by getting the interior of the trailer coated with non asphaltic pickup truck bed liner coating. The inside of my gen shed was painted with light gray Sears two part epoxy paint. Ventilate the enclosure with fans pushing air from outside to inside, exit vent high and as opposite as feasible. My gen shed has over 240 watts of forced air intake. The fan needs to run for 1/2 hour after charger shut down. That means using a battery voltage fan or fans.
Many utility motive batteries have .250" plates.
