Where do I look for the version on the board? I'm running one of the very early versions.

I bought a couple of control boards to do 'brain transplants' into older industrial controllers as well ... but they are just the control boards and have not been installed as yet. Too many projects! Or .. maybe not enough spare time?

What setup are you running any pictures ?
I killed the controller .. or at least the IGBTs .. by connecting the battery up backwards and Paul believes that the built-in diodes on the IGBTs just melted. I have not gotten back to the project ... I have a SEVCON controller mostly working in my Polaris Ranger EV. But it needs other TLC ... and I'm slow
I know you build your system a while ago.

I don't understand how to connect J43 & J44 "high voltage DC monitoring", do I need to wire resistors in series here ? eventually I will be using a Leaf pack 360V
I don't have J43 and J4, that I can see. The only controller that I have dealt with that monitors the high voltage pack is the Netgain Industrial controller. It has one connection on the pack side (+) and one connection on the negative side of the pre-charge resistor so that it knows when it is safe to close the main contactor. That way, you don't really have to configure the controller for a particular voltage ... it's just looking for the voltage across the resistor to be low and not changing fast before it closes the main contactor and opens the pre-charge contactor.
In THEORY there is no difference between Theory and Practice
