Should be fine as long as you know how to use it properly
use higher temps for unleaded solder, the rest is the same.

Ok great
Nice work dude!
I think it’s important that you have a method of rigidly ensuring that the two sides stay separated from one another.
I often use little 3d printed pieces to achieve this, but i’m sure there are plenty of other options too.
If you wrap this entire battery in heat shrink, there is a very real possibility that the tension could cause one side of the battery to ride over/under the other side.
Some sort of rigid spacer between individual groups and a full lap around with fibre tape should be enough

My enclosure is too thin to allow the battery to allow

So I just plugged my board in for the first time, and everything powers up. The only problem is that it doesn’t charge. I wired it as the above diagrams showed. Any thoughts @MysticalDork ?
Pictures of your wiring may be helpful
That’s nice and clean. Heck yeah.
In my experience fibre tape is easier then kapton for holding the bms wires down.
At least my kapton tends to come up after a bit

I really dont like the wire set up any suggestions
shorten your runs until it stops making sense to shorten your runs, also nylon webbed sheathing does wonders.
Is it safe to charge?
first of all, why is this backwards coloring? it should be kept consistent for the next steps of assembly.
I only realized after I finish soldering the connector, but I made sure that the polarity was right.

I figured you had the polarity right, and it’s also good that those are keyed connectors but it’s still best practice to keep colour consistency, in case anything needs to be cut you will still know which lines are positive and which are negative.
it looks good, but I would get another set of eyes on it before taking anything I say as advice.
