Either scissors or a nice sharp set of flush cutters. Most diagonal cutters have pretty blunt cutting edges, designed to stand up to abuse like cutting bailing wire and steel nails. You want a set that is specifically for copper. The blades are FAR sharper, but if you cut anything harder than copper you’ll fuck them instantly.
Grab one of these. https://www.amazon.com/HiLetgo-Capacity-Discharge-Analyzer-1-5V-12V/dp/B0716ZL1SM/
Tin it then cut it much easier and stops it from fraying
I use a pair of Klein 22003 utility shears for nickel and braid. Feels like hulk scissors. Sheet metal, whatever. Chomps through anything like butter, no fraying.
Highly recommend. Like some hybrid scissor/sheet metal shear combo.
Yup. That’s some chonky stuff right there
Joining the gang here, almost had to go to beat some fuckers up in china to get my money back
and lost 100$ on customs
that braid definitely looks a bit diff from I’m used to seeing

These are cheap, convenient, and have a capacity test function. But it’s slow, and cheap so a bit inconsistent. If you’re patient they can be had for about $20. Popular with powerwall scavenger types.
I’ve had good luck with these

The cutters are more precise than most diagonal cutters. The button is annoying though.
I noticed that one of my cells is about 0.3v lower than the others. I tried to leave the charger in for a couple of hours after getting to 100%, but it doesn’t seem to balance the cell. Is there a way to fix this?
are you looking through a bluetooth BMS or multimeter?
Bluetooth
If you have a smart bms you can set it up for active balancing which means after the pack is fully charged the bms will start to balance the p groups out. It’s slowly but it works
Ok, I’ll have a look in the app, thank you.
0.3v is pretty significant. Are you sure nothing came apart in the pack?
I don’t know, I have the pack wrapped in heatshrink, so there is no way to check without removing it. Do you suggest unwrapping it to check?
If all groups are at similar voltages but one single one is 0.3 low, very likely something happened to that P group. That much drift is not good
That should be right, yes.
