Nowty Towers DIY Battery Project

I'm thinking more about a plastic slip on cover like you can get for live bus bars in AC consumer units, I just have to find one with enough depth to cover the 20mm wide DC bus bar.

could 3d print something? (I'm happy to print and post to you)

just set some terminal covers printing for my Nissan leaf cells to see how they fit

probably won't use them, but handy to test with before I make my own

Have you thought about kapton tape over them Nowty?!
Not perfect for protection compared to a full blown cover but takes most what ifs out of the equation and very easy to apply and remove.

Plastic trunking?!

I’ve seen 3D printed terminal/busbar covers. Are you planning to do something along those lines? I’d be terrified of an accidental short…

Generally no, its in an inaccessible place, but I will be protecting the power take off points, they really scare me if the upper terminal post was to fail and the upper bus bar was to slide down. But probably no drama as the forklift fuse would blow.

Secure the negative cable to the plywood base and that should be more than adequate to prevent the busbar moving should the terminal post ever fail.

Small angled wooden deflectors would help. Could mount them on the positive busbar. 3d printing would be cool.

Its sort of like that now as the cable is so stiff, but I think your idea of fixing it to the plywood is the best permanent way to go.

The current power take off bus bars are temporary, 4mm thick tinned copper bar is on its way on the Ali'Express.

And I was talking bollocks about being no drama with the forklift fuse blowing, well it would blow because of the other battery banks feeding in, but the short circuit on the new battery bank would remain.

20-20 hindsight I know but extending the plywood so it juts out between the +ve and -ve would've been a great idea.

I think I will also fix the busbars together onto a plywood backing sheet so both bars are effectively fixed with respect to each other.

During your escape you seem to have forgotten to take SWMBO

I was actually running away from SWMBO's fury when she found out I had bought more batteries.
