It seems like it was set to 7200mAh. I used to set it for the exact capacity (in your case the full 8000mAh) - and created a profile for each of my batteries (back when I set them for exactly 2C charge rate and stuff). Got way too complicated - and since most tracks and racing series now have a maximum charge and discharge rate specified (12A / 20A), I nowadays only use one general setting for all batteries - with the capacity setting even completely turned off.
