Got these new 280ah eve cells today and this was the first time I’ve seen the welded terminals like this so thought I’d give them a try seems like a lot more contact area

Can you please tell us where you buy them from? Thanks!

If you buy 280Ah cells directly from EVE they come with these terminals.
f.ex https://www.alibaba.com/product-detail/EVE-lf280-lifepo4-Battery-Cells-280Ah_62430842455.html

Be warned though: there was someone on the forum who bought from EVE directly a couple months ago, and the cells weren't packed well, some were damaged when he got them. Not sure if he ever found a satisfactory resolution.

These were from a US seller that buys from eve directly and eve welded the terminals on I guess. I would have to go look and see who they were I got the link off a YouTube review of the cells

I love those terminals, much better than the single studs I've seen/used on other cells. One thing that came to mind as I was tightening though is the screws being away from the terminal, as you tighten, increased rotational force is put on the post. I'm sure it's not a concern, especially since EVE sells them that way, but was careful not to over do it.

I was thinking the same thing. I think it is a superior terminal, but you can't go 800 lb Gorilla on it.

That factory weld is a work of art. I would select these terminals any day of the week.

We always use a K-Tools 1/4" beam torque wrench. Generic ones are only $20-$30 on Amazon. Small price to pay to keep from turning a perfectly good cell into a paperweight.

What I like about them is they appear to be helicoiled, so the threads should be steal to steal, not aluminum. Can’t say I’ve seen many helicoiled cells before but it make sense.

They do look helicoiled. Good eye!
