This is what I boughtThe victron lynx series has both a fusable positive busbar and a non fusable negative busbar.

Photos are worth thousands of words.Yes, I did that just "to see" but that is def not the way I want to do it. That's my question tho, how to do it clean :D @Supervstech gave an answer I can understand and even feel easy to do. And if I understand yours, welding is the worse option to consideer. I understand the idea of making holes in the busbars, but then I miss smthg: since those busbar are connecting units together, where shall I do a new hole to make sure the contact is done specificaly with the positive pole?
For which circuit?This is what I bought
Fuse is 175A. Calculated this way: My inverter is victron Phoenix 2000VA, 4000w crest. So 4kw. So 4/24 = 0,166For which circuit?
What is the ampacity rating of the fuse?
What is the awg of the wire?
I see! But (I might be wrong: remember the topic, I'm a total noob) if I m no wrong, it works with you because your units are paired in parallel, so one busbar is pairing both + of units. While for me it's all in series so I have no full positive busbars. So I guess if I make a hole in the middle of the busbar it wont work at all. Did I win?Photos are worth thousands of words.
No individual cells are paralleled, there are 2 16s/48v packs paralleled at the current connected bus bars.I see!

Ok so u just make a hole in the middle of a busbar connecting the - and + of units? I'm impressed! Again I know nothing, but it sounds so special as they insist to plug these cables to positivesNo individual cells are paralleled, there are 2 16s/48v packs paralleled at the current connected bus bars.
Yes, but you still connecting to the positives even in the middle of the busbars. Think about which way the current to the BMS runs irrespective of whether your + of one cell is connected to the - of the next cell.Ok so u just make a hole in the middle of a busbar connecting the - and + of units?

Ahahahah that could have happened for sure Thanks mate!Yes, but you still connecting to the positives even in the middle of the busbars. Think about which way the current to the BMS runs irrespective of whether your + of one cell is connected to the - of the next cell.
Just remember to take your busbars off to drill them as we don't want to see you in the ‘Up in Smoke‘ forum
Now that I understood the fact the whole busbar is actually like the positive pole, I still am wondering how you get those really tiny cables to fit into this hole? I see you used some sort of nut but how is the cable attached? Thanks a lot for your ideas btwI would drill and tap holes in your current buss bars to install the balance leads instead of stacking on the battery terminal.
Ring terminals are crimped on the end of the balance lead. The bolt goes through the ring terminal to fasten to the buss bar hole you drill and tap.Now that I understood the fact the whole busbar is actually like the positive pole, I still am wondering how you get those really tiny cables to fit into this hole?

Is it fine u think? Thanks in advanceFor which circuit?

But then... What's the difference with just using the "bolt" that is already on the battery unit? Beside that you can choose a tinyer one? And how did you manage to crimp the ring terminals on such small cables? As mentionned yesterday, by stripping and folding them?Ring terminals are crimped on the end of the balance lead.

Yes, stripped and folded.But then... What's the difference with just using the "bolt" that is already on the battery unit? Beside that you can choose a tinyer one? And how did you manage to crimp the ring terminals on such small cables? As mentionned yesterday, by stripping and folding them?
You need ring terminals in the size that either fit your terminal bolts or the bolts on the busbar like these.But then...
