Moinsen, one question only indirectly to the G: I have a boat with a 2.2L diesel engine, Lima makes 80A at 12V. I would like to be able to switch on and off the minus cable from the engine to the starter battery. I think of a Nato bone. Only there are quite a few. The most common is from Hella, who is allowed to withstand curatively 1000A at 24V, permanent load is given with 50A. Can I take it? And, could I also take it for my G270? I regularly forget to remove the ignition key. before, so my batteries like to die the early deep discharge death (I drive the only one or two weeks). Greetings Carsten
