these packs are made of molicel IMR-26700 IIRC. and their construction is a straight up pain in the ass, not to mention unprofessional on their construction. its amazing they got that past any inspection agency.
you can recell those blocks if you want to. but i would just take the original box and just cram the thing full off 18650 cells and enjoy the higher capacity and power delivery. those molicel cells are junk. do make sure you keep the old bms as the bike wont like it with the bms missing or you have to program the bms lockout function out of the secvon.
