Can this cell post be fixed?

[nicoloks]

Hey All,

Have had 4 x 3.65v 302Ah CATL cells in my caravan for 18 months. After a recent 3 month trip on some rough off road tracks it seems the corrugations were enough to break the positive posts on one of the cells.

Can I fix this, or is it new cell time?

Pretty much time for a new cell. If you mill it off flat, carefully drill and tap the terminal (*), and bolt a lug to it, you might be able to make it work.

(*) Oops! You just drilled or tapped through the top of the terminal into the internals of the battery, and destroyed it.

Where the lugs on the EVE batteries are welded to the electrode is really tender. I've read a couple of other threads stating they've had issues with them coming off when tightening the bolts. - it's not just me being stupid.

disclaimer - I've been using tools for the last 53 years, my mom gave me a took kit when I was 7 and I've been messing things up since. I have a very good feel for "tight" and such. I'm also a machinist/fabricator so I can claim that I know what I'm doing, for the most part - including screw ups... (I like to call them teaching moments)
