I have a KT40 kunteng controller, 12 x 4110 FETs
http://www.szktdz.com/en/news_show.php?article_id=502
I beefed up traces etc, and did a shunt mod. This made it go to some 85A battery current / 160A AC phase current measured with clamp current meter.
So in this 12FET controller of course two 4110 FETs are sharing this 160A phase current, and the FETs are rated 120A continous. I know they are not sharing the load evenly, so it might be one is taking much more than the other. Also an unknown is - what do transients look like and how much avalanche is happening.
They FETs are not heating much and have decent airflow around controller casing.
What do you think, can this last? What is the most you would push this controller, battery/phase current?
Thanks
