I ordered today and they were delivered the same day as promised. Solid construction with quite a hefty to them. I'm going to be using them to connect 4 Lifepo4 batteries to a charge controller and a 3000W inverter charger. 300A is over kill but better safe than sorry.


I think theses will will handle more power then the other cheaper ones out there


I bought these as power distribution bus bars on one of my smaller solar power systems. These bus bars are made of tinned plated copper bus bars with a 300 amp rating. The bus bars are very strong with six 3/8" studs and protective covers. Great for heavy gauge cables moving lots of current.

These bus bars are very capable and have high conductivity for a low resistance connection. If you want a great connection, make absolutely sure the bus bars are copper. They are very easy to install and have lots of room for expansion.

These bus bars are a terrific value for the price. I highly reccomend them to anyone looking for good bus bars for solar, RV, Marine and other applications. I give them 5 stars.

For the money and being rated for 300A they are decent busbars for where high amperage connections are needed.
Is decent for people who are looking for a little larger bus bar on a small budget.

Well made hefty bus bars that function above and beyond my expectations. I have these connected to a 48 volt battery bank of 600 amp hour (3 strings of 4 lipo4 batteries) that supply power to the 10k hybrid inverter. These bus bars are awesome, if you are using solar panels and very expensive lipo4 batteries then you really need these bus bars.
