this JK-BMS model comes with impossibly short B- and P- leads
It's exactly this kind of thing that makes buying a finished battery a better idea than DIY.
Why not solder the bigger wire directly to the board?I'm thinking of just going with this kludge job.
Shrink tubing is fine. But you should either cut that bolt shorter or replace it with a shorter one first.@Steve_S made that beautiful cable, I'm thinking of just going with this kludge job. After seeing those blobs of solder holding the wires on the motherboard, this is hardly worse. Unfortunately don't have a shorter M8 bolt handy. What's the best way to insulate this? Just buy giant shrink wrap tubing?

So when you were ordering parts for your first DIY battery, you had the forethought to look at those leads and know, in advance, you would need 2 extra busbars plus supporting ring terminals, and you ordered everything and had the extra busbars ready when you started to assemble them, and this caused no delay for you
that you crimp or bolt main battery connections, not solder them.
This is incorrect thinking. If you have no qualifications you need to retract your statement.No it's not. I am a complete noob with zero qualifications and even I know that's wrong.
