I used two sets of these busbars in my solar system install. Busbars make using multiple charge controllers super easy. Work perfectly. Heavy duty.

I used these to clean up my many boat battery leads and they worked out great. Only have main connections and onboard charger leads on the battery now.


These worked great for putting three large 12v batteries in my rv. I used some electrical lube so the nuts wouldn't stick after snuging them down.

Bigger then the picture made it look which is good when using 0 gauge. I haven't installed it yet but it seems like it's going to work perfect.


I haven’t actually installed these yet, but I’m impressed with the quality. They are perfect for my application of wiring a Mustang with the high torque mini starter. I can eliminate the ugly fender mount solenoid normally installed on all Fords. The mini torque starter has a solenoid already. I’m sure you will be happy with these Bus Bars.
