I bought them, I don't have the Amazon ones to compare to. The Current Connected seem solid though I haven't got them hooked up yet.
I wouldn't hesitate to buy them again or recommend them.
I like the additional smaller screws for connecting small items that I'll probably never use ?

I can’t speak to current connects 250 amp busbar you mention, but I do have a 250 amp blue sea bus bar I stacked next to a 250 amp brass busbar and Blue Sea is much better.

I have two sets of THOSE busbars and during the Thrash Testing some time back, at 100A they got warm, by 150A they were "hot".
Victron & Bluesea certainly have good busbars and will handle their ratings, they are also a lot thicker.
I'm now using these from Pike Industries, they are thick copper & serious for a fair price.

Thank you for the info, I will keep a close eye on them when I put everything under a load test.

I'm using these, always sold out, 500+ sales already, the seller is the manufacturer and says they've been in business for 100 years, so I'm sold

My loads are low

...Although the thermal scanner is on guard

A set of 300A busbars for $40 sounds amazing, I'd also like to know more about their behavior during a test. My battery bank fuse is 125A (class t) and I want to use the new busbars on the loads side. I don't need them to be all-the-way legit is what I'm saying I guess, worth whatever a 125A fuse will allow through (so handling 150-200A surges would be good, not 900A surges like the specs).

But they're not in stock! I wouldn't mind trying them if they come back.

I think I'd buy a lynx power-in (~$150) before buying two $60-80 (each) amazon busbars. The lynx power in is rated for 1000A I think! And I could see using the fuse holder hack for it to hold some mega fuses for my inverter and MPPT.

The current rating we provide is straight from the factory's spec sheet.

You guys like my high-current testing videos, so I'll make one on these this week. If I feel that they get too hot, I'll adjust the listing accordingly. Just like on the SOK Battery front-panel terminal feedthrough test - I did the test and came up with a spec that I thought was a safe figure. Later, I dug deeper into the documentation and found the actual spec of the terminal was within 10A of my determination.

The only thing I'm missing in these videos is a thermal camera...the main reason I haven't bought one is because often times thermal cameras struggle on shiny/reflective objects, which is what most of these bus bars are. No excuse though, I do have thermocouples and can use them instead.

It also depends on how you run your connections - if they are running through the bar or lugs stacked. If they are stacked directly on top of each other, then the current is as much as the wire used is rated for.

I know @Will Prowse has been using them for quite a while now on his main off-grid system and hasn't told me they suck. If they were trash I wouldn't carry them on the site.

You can always buy bigger, beefier bus bars like the Victron bus bars...but expect to pay a lot more money.

Funny thing to me is that a Lynx Distributor & Power-In is rated for 1000a, yet the 600a Victron bus bar linked above is about twice the cross-sectional area of the Lynx and almost half the rating...

I agree about the apparent rating of the lynx devices versus the 600A busbars... The 600A option seems way bigger!

Oh this is strange, I thought we just got a couple hundred of these in. I am going to the shop today to make a few videos, I'll verify stock and if we are incorrect on our quantities I'll update the site.

I do know there is a pallet of them on the ocean arriving in about 30 days, but the couple hundred I thought we just got was supposed to hold us over until then

I am curious to see when you file down a corner to know what you have hidden under the "shiny". Also if they are Chrome plated versus Nickel (better conductor), I would wager Chrome. * Some busbars shipped by vendors are Chrome Plated Brass and not Nickel or Tin Plated Copper.

Look at the size of the Blue Sea class T holder in relation ?
Should I be irritated ?

Whoa, is that the Current Connected busbar?????

It is indeed.

I recently upgraded my Current Connected busbars to a Victron Lynx Power-In.
The original current connected busbars were more than adequate for my modest loads
As my system and loads grew so did my busbars

Original CC busbar(s) are 3/32 inch - about the same thickness as the lock washer ~ 13/16wide
the busbars appear to be copper
the 300 amp rating seems about right, maybe a bit generous

full teardown pics:
lots of plastic, head of the bolt can be seen in the area filed away


Busbar is threaded for the bolts.
Seems a bit underwhelming, if it were to give there's nothing to hold the bolt from spinning although I suppose the innards lock washer could bite into the plastic to hold. I seriously doubt there's a problem here though.


A bolt


What the innards look like


Overall impression:
Good for the price but only for modest amp loads
keep well below the 300a rating

We organized in the warehouse today and got everything tracked down, they are back in stock now.

I will get the video made as previously mentioned at my earliest chance.

Thanks everyone!
