Not sure if theses are beginner questions but here goes.
I bought 16 230 ah eve cells from Basen. They are excellent quality. well matched and all perform well above rating (I am seeing between 239 and 242 ah when testing them). The only issue I have is a single stripped stud. They have what appear to be welded in studs.
Not sure how it happened, I have been torqueing these the same since the beginning. I use a torque wrench and set them at 15 in/lbs for general testing and charging and at 20 in/lbs for final assembly.
2 questions;
First is, are these torque numbers good? I have never been about to get a spec from the manufacturer. I would like to know that I did not cause this issue.
Second, any ideas how I can repair this stripped stud. Ideally I would try to either thread it to M5 or remove it and replace with a grub screw. I have the ability to thread and (if necessary) Heli coil the hole. Advice?
