I All !
I’m using a focbox with a 4kW motors and a 12S Lipo Battery. Everything works fine but the Focbox mosfets gets hot really fast: from 48°C to 76°C in less than 90secondes, pulling maximum 60Amps motor and average 40°C.
You can see the datas here:
The Focbox was inside a box so no cooling but even though, I didn’t expect it to get so warm so quickly.
What I don’t understand is that the Focbox is rated for 60Amps continuous. Is it only under perfect conditions with a really big fan blowing directly on the fets ? Or maybe is it because my focbox has an issue somehow ?
Any advice/ opinion is welcome here
