Neodymium magnets dislike heat, as long as the pack never gets a hot cell or 3, all is well. Batteryblocs are quite large and take up space. But they do work. I like the V2 Vruzend for a more compact solderless build, and no magnets.

Bob’s box rocks! I like it!
Yes I saw those as well. My concern with those is that the caps just slide over the ends and they are not clamped from ones side to the other sandwiching the battery between them. I would be concerned that they might lose contact with the battery over time from bumps, expansion, etc?

They are snug enough if you follow the directions. I use a plastic top and bottom and zip ties. All good...
Thanks Justin_le we're here thanks to you. All the best to the mods for their tireless work keeping it on an even keel.

Ahh zipties, good idea :) Thanks, I will look into them as well when I build my next battery.

more of the same
Looking at doing the same. Lost this one in a fire. Has anyone adapted a through post ring swing arm to drop outs for a mxus 3kw?
Any help would be appreciated for my next build.

It is not a full enclosure but it fits my em3ev triangle pack nicely. Its just some 22 gauge steel bent up to fit the bike frame and fastened with u bolts. There are some metal loops fastened to the side to anchor the hook and loop straps that secure the battery down.
