Ik wil graag mijn (drie) Seplos Mason 280S batterij pakketten met 70mm2 bekabeling aansluiten. Ik gebruik liever een dikkere kabel dan twee keer een 50mm2. Heeft iemand ervaring met het aansluiten van 70mm2, en zo ja, welke batterij connectoren gebruik je dan?
Wat voor Victron (Multiplus?) heb je
I use the 2/0 AWG (70mm2) for battery connections all the time. I get the proper size tinned copper lugs, crimp them and heat shrink. Many technicians do this with no issues and prefer it over two smaller conductors.
This is an important question as you would want to match the battery cable size of your parallel and series connections with the cable size from your batteries to inverter. It sounds like you are using a Multiplus 3000/12V model. You should use the closest equivalent of 2x50mm2. Our 4/0 AWG here in America is about 107mm2. That is what I use.
De Multiplus ll 6k5. Dat drie maal voor drie fasen. Ben van plan die met een Lynx distributor aan elkaar aan de sluiten. Uiteraard ook met 70mm2. Met een tweede distributor wil ik dan de drie Seplos boxen van ieder 16 314 ah cellen aansluiten. Die dan ook 70mm2. Maar de batterij connector op de Seplos lijkt zo klein voor 70mm2
I am not familiar with the Seplos Mason 280S. I have looked them up and they appear to have a specialized terminal that requires their cables to connect. Is this what you are working with? Also they have terminals available but they only go to 50mm2.
Indeed that’s the Seplos and its connector. So I was wondering if it is possible to change the connectors to ones that allow 70mm2 cables. If so, what connector would fit the Seplos front plate
So you have (3) of these? Victron definitely recommends 70mm2 for the battery to inverter connection.
I wouldn’t recommend modifying the terminals on the battery. You could oversize the cable though and still use the Seplos terminal connectors. Its not ideal but would work. If you have a simple thermal camera or laser thermometer you can monitor the cable temperature when the system is under a large load. It will probably be fine. Make sure you fuse properly. That will save you if anything does go wrong.
Another interesting observation is that the terminals on the battery are the wrong colors. Black for positive and red(orange) for negative. That appears to just be this picture. On their website the colors are correct. Strange.
Thanks for your response. I will try the default connector first. You are right about the picture. The current one (that I have) has indeed the positive and negative swichted. Of course the printboard layout also changed due to the switch. Now the board manages the negative. Before it was the positive. Their manual is up to date. But all online videos are on the old one. That confused me somewhat. Fortunately ChatGPT was able to help me out 
In case anyone needs them —> gobelpower.com (picture from their website).
On a second thought. I would rather use something like this: Single Stud Type Junction Blocks 200A Internal Screw (M8) Busbar with M6 Flange Mounting Black

You really want a cover over the terminal, product in your link has no cover (provided)
Ik vraag me alleen af of deze niet te groot is als ik naar de Seplos kijk (er zijn kleinere versies met minder ampere)
Van welke site heb je deze?
Yes indeed!
Luckily they have more products than the example I shared here. Including one with a cover. But some people just print them at home. Or have a friend with a 3D printer.
