Hey Guys,

So I have good news!! As of today the new firmware, v1.8, can control pre-charge time!!

You will need to hook up a relay to close when the 12V is turned on to the controller. When this relay closes, it will allow power to flow from the traction pack, around the contactor, through a pre-charge resistor and charge the caps. When the controller has been on for the pre determined amount of time, it will close the main contactor using the already built in contactor output!!

Also, You want to make sure you dont connect the contactor control output to the contactor with any version lower then v1.8. If you do, it will close the contactor immediately.

I will be working on testing this version out within the next few days. After I do, I will post a like to it.

-Adam
