Need some hints

Hey all

im trying to build a battery bank for my Electric motor bike,I think the old batteries were "Thundersky 260 LiFeP04" and my bike is from 2009 and i can see at that timemy bike didn't have a BMSinstalled, later models maybe had it?
Is there anyone here who could possibly come up with some good advice, link to how to build a powerbank?

thanks in advance

my bike is like this one "xm-5000 electric
