Heavy duty metal parts; plastic backing plate could be more substantial
I wanted to double-up the battery cabling on my home energy storage. This terminal block did the job real nice. It was a job torquing-up the M8 bolts to the specified torque, without twisting them out of the backing plate - had to hold everything quite tightly with the other hand, but it was doable. Measured the temperature of everything while at full load for 30 mins, and barely any temperature rise.

Praktischer 12V Stromverteiler | 2 in 1 Busbar für Plus und Minusverteilung
Im Wohnwagen meines Sohns ist nicht viel Platz und da macht so eine KombiBusBar mehr als Sinn. Platzsparend montiert wird sie die Kabel für den Anschluss einer LiFePo4 Batterie, des zugehörigen Ladegeräts, des zugehörigen Ladeboosters, einem Mover und für die 12V Autarkie des Wohnwagens genutzt. So können die Enkelkinder unterwegs auch mal zur Toilette gehen, wenn gerade mal kein Rastplatz in Sicht ist.

Not a safe product
This product should be removed from Amazon. They state that the color code the terminal post for positive and negative which is untrue. If someone was to mix this up while wiring it could cause a total system to failure. As well as a fire. There is no markings anywhere once the cap is removed.
