Vibration IS the issue. Everything else is a minor detail.
At that time I thought my batteries were well built however I missed so many things, I didn’t use fish paper between P-groups, additional fish paper on positive terminals, didn’t secured my batteries to the enclosure with heavy-duty double sided tape, used only one layer of 0.15mm nickel, strip, used a bad nickel strip material which rusted over time, didn’t used kapton, didn’t use enough isolation on bare wires, used a bad technique to build flexible batteries, lack of isolation on charging port, used bullet connectors instad of XT connectrors, so many things I do now and after all this gained knowledge the risk of fire is still be there.
Just came from the lounge to see what all the fuss was about and daaaaaaaamn! Dismantle that bomb and do a lot more research. It is all here for you to access.
ok, guys i will stop constructing a nuke and i will buy nickel and start again… thank for your attention.
There aren’t too many resources on here about building a battery pack but hopefully one day we can get an experienced builder to make a how-to/guide.
The best I found so far is this
that’s why I said good technique but not great. Thanks for the detailed run down though on the improvements.
The new packs look pretty damn nice.
Guys check this pack.
I didn’t really see how the ballence wires where run though?
I’m not runing any bms on my Pho3nix, I’ll install a Bestech d122 for charging as soon as I receive it.
Here’s how you should wire the BMS using my improoved technique
Looks like a kaly pack. awesome work
Way to improve your build!!
No, it’s mine
This Nikkel strip is good?

That strip is 25mm wide and your cells are only 18mm wide.
but still works? I did not find anything else
i can cut to 18mm
Why would you do that… Just buy the right things
you will find all this info and more in other threads on this forum. search and you will find. that and experience is how 90% of the members gain their wisdom
if stacking 2 layers of cells and using one strip on both layers, 25mm would work with no cutting. @longhairedboy did it if I recall correctly
Aliexpress has some 8mm 0.2T nickel…
Though u need to buy a kilo…
If u need small amount, maybe I or @rojitor can help out.
What welder are u planning to use?
And always check the nickel from AliExpress by put them into salt water and look if they become rusty after one day. They write it’s 99% nickel but often it’s not
