Xuba 280ah cells with JBD BMS in a Peli style case. Snug fit and some minor work left to tidy it all up (isolations on connectors etc). Tried to make it as "secure" as possible given vibrations; loctite on pretty much everything, 20mm stainless studs for poles, cells taped to a bottom plate of plywood, everything squeezed in the case between the foam. Ran a 1h test with 60A load and temp was 35C on BMS and 20C on cells, but will do a longer test with higher load. Two of these will power a max of 100A combined when put to use. Any input before I finalize it?

Very cool build, the tape should work as long as the batteries can't move around...ruff sea's will move anything not tied down move, so they have to be tightly fitted.
1. I'd like to see the spaces on the right and top (by the handle) of the battery filled to prevent lateral movement.
2. Positive lead is too long, get rid of the loop, as the kink at the top of the loop is causing resistance and has stressed the connection at the battery. Possibly some heat shrink to the connections.
3. Does the positive need to be fused between the battery and the case?
