    Here is the load bank so far. The heat sink is drilled and tapped. Went M3 on the fasteners. The entire project will be M3x10x.5.

    The connector is a castle creation 6mm EC style connector. I have the current sensor wired up to the load bank. I have yet to get thermal grease. Not sure if in really even need it. I washed the heat sink after tapping it. I took off the resistors washed it in hot water. Arts bed the resistors and the heat transfered to the resistors really quick.

    Now u have to build the container which will be lexan since I have that already on hand. I have drafted out the pieces on paper to actual size.

    Next I need some kind of cutting tool for this. I have I have a router, a circular saw and access to a table saw. I am thinking of rough cutting with the circular saw and trim cutting with the router. That should net me some smooth edges.

    That's it for now. More later.

    12V equalled 12 amps at about 130F on passive cooling.

    Next is going to be 15V at 15 amps with passive cooling. Going to see at what point the heat sink will need forced air to stay cool.

    I have yet to use heat transfer grease.

    Sorry for not keeping up with all of this. Sounds like you are making great progress on this. Keep up the good work. Oh, and sorry for missing your text messages. Or not replying anyway.
