I'm setting up an 8S pack of Eve cells with M8 welded studs, and the studs are too short. In the middle of the pack, where the bus bars and BMS leads connect, it's fine, though not ideal. At the ends, where the thicker cable lug connects at each end of the battery, it's flatly unacceptable. Especially so on the positive side, with the BMS and shunt power leads in place. The nut is grabbing maybe 2 threads on the stud.
Current plan is to put a coupling nut on the stud, thread another stud into the top of the coupling nut, and connect the battery cable lug, BMS power, and shunt power to that stud. Make sure everything is clean, use no-alox, and inspect frequently. This isn't ideal, but ideal isn't an option. Just meant to be a better solution than only two threads on the nut grabbing.
I'm not the first or only one to have this issue, how are others handling it?
Thanks all.
