I have been using this pack in my EV for about 2 years. I am estimating I have run the equivelent of 200 cycles. I will post more later with a better estimate based on miles driven on this pack.
I want to upgrade to a pack with a higher C rating. This pack would really be more suitable for a light golf cart. I am located in Hawaii, so am hoping to find a local buyer. Shipping to a port on the west coast would also not be that costly.

Were they under BMS management? How do the voltages compare between cells? What charger were you using? Might be interested in them for my VW Rabbit, on near Long Beach, CA.

I originally had a charger/balancer supplied by Hipower, unfortunately I had issues with it from the start. For one thing it was 110 v 25 amps, so I had to have an electrician install a special plug, which limited my charging to that location. Also the balancing function never seemed to work properly.
I ended up putting together 2 meanwell power supplies as a charger. It works as a constant current (about 600w) constant voltage. I can adjust the voltage, and I have been charging to 83.2 V. at this level the highest cells hit 3.68, and the lowest cells are 3.40. I used a single cell charger, and a light bulb to do some balancing. At this point the pack seems quite stable.
This pack alone would not be enough for a rabbit IMHO. They are rated at 1C constant. Would you be using it with another pack?
