With how you have carried on about joints that are not in Al and Cu studs I find your statement above a bit humorous. You have conveniently ignored the questions I posed above. So here they are again. What is your experience with prismatic batteries like the TS or CALB cells that many of us are using? Is your pack put together with no terminal prep and no washers? What is your climate like? Those are the joints that this discussion is about. The fact of the matter is that some people have had joints loosen when using the OEM supplied SS bolts & split washers and when they went with nord locks, the joints quit loosening. I went with brass bolts (because they are much easier to center drill and tap), a bronze lock (split) washer, a brass flat washer on top of layered copper straps and have not had any joints loosen. Also, I know of people who didn't clean the battery posts and seal them with something have high resistance joints down the road a way. When they sanded/filed/wire brushed the surfaces and applied a dielectric grease of some sort then reassembled the pack their issues disappeared. Maybe they did something wrong with their initial assembly but the cure worked. Maybe I wasted my money buying bronze split washers and brass flat washers but it works. I would still like to know how many miles you have on your LiFePO4 pack of TS, SE, or CALB cells and how the joints are holding up. If you don't have such a pack in a road going EV then please get one ASAP and assemble the way you think it should be done and report back how it is going over the next 5-10 years. -- David D.
