Lithium battery, replacement parts available? (Terminal)

I have four victron batteries, 60ah that I bought second hand last summer. Two of them were perfect but the other two were of unknown history. They each had one bad cell. I took the casings apart and made one good battery from the two, which left me with two spare good cellls.


Last week I bought two new winston 60ah cells to complete the fourth battery. My issue is the threads on the terminals have become damaged making it impossible to thread the nut back on, and it’s this nut that holds the lid on the casing.


The terminal and nut are aluminium. Does anyone know if these parts are available off the shelf somewhere so I can replace them?


I only have this picture for now but will get one of the part in isolation later. Terminal is circled in red without the nut.

You could consider repairing the threads or going up a size and re-tapping them. Helicoil type inserts for repair. I would try the re-tapping myself as I have taps lying about.

It’s the external threads that are the issue. Also as I have 4 batteries in parallel I need to keep them all the same so the resistance isn’t altered. Two of them the cases are still intact.

Be brave, and run your big yellow cells naked. Blue clothing is optional....

Haha. Yeah I could, but they come in a nice sturdy case with balance circuitry. The two I opened up got damaged in the process as the black silicone over everything took two of the resistors off with it /:
