The photographs and notes posted by others suggest the configuration is probably 6P8S.
In other words there are 48 cells. Six of these are wired together in parallel to make sub-batteries (increasing the capacity), then 8 sub-batteries are wired in series (increasing the voltage) to make the main battery.
The 8 sub batteries are balanced but the 6 cells in parallel in each don't appear to be. However that's not usually a problem because cells in parallel will tend to auto balance...
Cell Balancing and Battery Equalisation
Self Balancing
Unbalanced ageing is less of a problem with parallel chains which tend to be self balancing since the parallel connection holds all the cells at the same voltage and at the same time allows charge to move beween cells whether or not an external voltage is applied.
