Looks very good - but where are you sourcing them in small quantities?I am trying this flexible buss bar.

NVENT ERIFLEX, ERICO Flexible Busbars, Eriflex Flexibar Series
I got like 79” for about $100.00 shipped from Galco.com, they have different amp ratings. I got 250 amp.Looks very good - but where are you sourcing them in small quantities?
That's pretty good. I assume you are located in the US.I got like 79” for about $100.00 shipped from Galco.com, they have different amp ratings. I got 250 amp.
Sure - keep the Forum informed as to how this work out for you.I am in the PNW, I am building three eve 280ah 12 volt packs if I have extra I will let you know.
The bar is flexible enough to make bends, I could bend a v for expansion length wise if it is an issue but I think going diagonal will alleviate most of the issues. This is for a mobile application so I will be monitoring the connections closely. Both 280ah banks are being mounted on vibration isolators.
Everything is going good so far, I am waiting on a 2800watt inverter and have only been able to discharge at 30 amps and charge at 50 amps. All the cells are staying nicely balanced no loose connections, they get bounced around a lot. I am putting together seven 280ah batteries, just finished top balancing number three.How have the bars performed in your setup so far? Any issues?

How flexible are they? I wonder if someone could show it (bending or something?)
After trying a few solutions to the flex-able bus bar issue for mobile applications, I am now using these very flexible busbars https://www.aliexpress.com/item/1005002755728521.html?spm=a2g0s.12269583.0.0.548b4d2eq9IcCJ.
These were also mentioned above in this forum thread.
At around $4 usd a piece, they are very good value.
With my prior busbars, I was having problems with resistance in the busbars over time ,giving false BMS voltage readings and prematurely tripping HVC.
To avoid stacking ring terminal over the busbars, I drilled holes in the corners of the busbars for #4 bolts & nuts to hold the sense wires.
I also am using the MG Chemical 847 conductive paste recommended by Upnorthandpersonal to protect the EVE's aluminum terminals from oxidizing and to promote a good electrical contact.
It's early days, so will have to see how this new setup lasts over time.

I have no way to measure.... but they seem as hard or harder than the lug connections on cables. Hope that helps.I am considering these busbars in my mobile application (van), but I have a question. My current commercial braided busbars somewhat feel spongy when I tighten the nuts, and I suspect this, along with vibrations, caused some of the nuts to loosen over time (the connecting sections on the busbars were probably not pressed hard enough - or were made for larger studs and higher torque). In contrast, the nuts on B- et B+ lugs in both my batteries remained tight.
When you tighten or torque the nuts, do you somewhat come to a hard stop?
