Thanks, I will do. I do not know the answer to your question yet, as I am not currently using enough to get them to the discharge to the cut-off voltage (set to 21,6V) This last 2 hour stage 2 load shedding saw them drop to 96% SOC. I am only using a small 3kVA Axpert inverter for load shedding, but the reason for the overkill on the huge batteries is for when we get to stage 8, 10 and beyond in order to keep some essentials running for as long as possible.
The batteries have a 4000 cycle warranty, so hopefully, they’ve should be ok. 

Both batteries seem to be fine now after cycling twice
