    Take this warning very serious. If you short the battery out, it will explode into a ball of hot plasma that will vaporize skin and bone into ash. OK? I care about your safety.

    Your batteries are MEAN and will NOT tolerate any mistakes. One short circuit will vaporize steel and copper and the PLASMA gas will turn skin and bone to ash. You will not even feel the pain. UNDERSTAND?

    Message read and understood - very clear - appreciate your concern


    I will use 2 x 70mm2 of cables on each side (basically because I got them) I consider increasing with a third making in total a 210mm2 connection. I just struggle to visualize the copper termination plate. Why should this not be connected directly on top of the four posts thus keeping the termination protected inside the battery box. I assume that a 400A fuse mounted on the bar would increase safety - bad idea?

More importantly is installation details making sure all connections use a good quality battery grease, proper quality compression tooling and installation technique, and using a torque wrench set to the proper torque per manufactures listing. ATTENTION TO DETAILS IS CRITICAL in your application.

    Where do I apply the grease?

    Compression tooling, like this?

    Torque wrench is fine, if I can't find manufactures listing - any recommendation?

A wrench dropped between two battery terminals may end up melting like a fuse, only more violently, or just sitting there red hot until you figure out how to break it loose. (Better to just go to a safe distance and wait in most cases. The key is to plan ahead what you would do in the event of an accident instead of just reacting when it happens. Kind of like training yourself not to try to catch a sharp heavy knife when you drop it. )
      Got this, I believe this issue is also the reason why there are no open buss bar on this battery pack - it's basically much to dangerous on a cramped oil platform out in the Northsea. The black interconnection covers all terminals - there are no open terminals to short circuit. The only way to experience that is if the terminals on each side of the batterypack get into contact with the steel battery container.

      And this is what this tread is all about - how to get this batterypack safely connected

        I still believe the battery manufacturer may have a standard termination "buss" that is used with those batteries.

        It may not have been an exposed copper bar but something like a termination box that allowed you to make the 4 connections with the battery as well as terminations for your load cables and everything was insulated to prevent short circuiting.

        Did you google the battery manufacturer to see if they have that type of termination box?

          I agree, I would have expected them to supply this. Did Google - no luck. The Norwegian dealer is supposedly out of business.

            Light coat on wire skinners and mating surfaces.

            Should be listed in the battery manufacture installation manual. This is not exact to what you have but similar. Look at pages 13 and 14 for torque values. Manual Here.

            Should look something like this when done.

              I found this battery that seems to have the same terminations for a 2 volt FLA battery.



              Not the same battery but maybe you can find terminations that will fit.

              Or this one which is a 1000ah 2 volt.



              or this one.



              or this one.

                "Wire skinners" = ??
                "Mating surface" = between the battery terminal pole and the interconnectors?

                  They look very similar - same "box" slightly different weight. Typical Chinese manufacturing style - Same "mold" used for multiple prands - maybe even the inside is the same. In this case some of the specs are at least different. Weight is slightly higher in mine


                  Thanks for helping - I'll give it a try

                    Those are Fuli FL210000SL batteries

                    I am pretty sure the batteries are of the Fuli brand and more specific the FL210000SL batteries. Fuli are sold under different brand names in Norway. The description in the top of the spec sheets are the same and the dimensions and weights are the same. Data sheet attached.

                      That certainly looks exactly like his battery. I checked their website but did not find any interconnecting cable items but maybe contacting them will get him closer to finding what he is looking for.

                        The Norwegian company that installed your batteries on the oil rig is still in business: www.getek.no and the dealer selling the identical Fuli batteries is www.alternativenergi.no

                        Correction: Getek is out of business!

                          Sorry about that.

                          Wire skinners are the portion of wire or cable where you strip off the insulation in preparation of terminating a compression connector onto the cable. You apply a thin coat of oxide inhibitor compound to the bare wires before you squeeze a connector on.

                          Mating surfaces is any place where you terminate a connector or the area where contact if made between wire connector and a flat mating surface. So you got it right, just all mating surfaces.

                              Soldering the cabel connectors?

                              Should the cabel connectors also be soldered?
