I cut mine , now I am going to tap threads on top of each post & insert battery "posts" from Canadian Tire so I can wire as I see fit.
If you new the post size & could find dead centre you could drill them off.
I had thought of this but found for me it was easier to cut them leaving round tops
that I can tap
if they are in rows like mine you just need to cut the ends& wire the 3 sets of 6 cells in parallel. I had to remove all mine , 1 at a time because of the weight.
