Marstek Venus E - Dual 140mm fan bracket

If you want to keep your Marstek Venus E home battery cool with some spare computer fans you can use this bracket!

I had quite a few 140mm fans left over from a previous project so I made a small bracket to bolt into the existing M5 holes on the battery. I also created a small piece just to couple 2 fans to each other. You can use any standard PC-fan screw to mount the fans to the bracket.

The screws I used to mount the bracket to the battery are: M5*12

Currently the fans are running 24/7 but I ordered some thermal switches to switch automatically. I also attached a screenshot of the internal temperature while it was charging with about 2000w. It kept things a lot cooler :)

It will be wise to also print out a fan guard. I am using the one from: https://www.printables.com/model/1098014-high-efficiency-noctua-140mm-fan-grill (not shown in the pictures)
