Congrats Arlo! Thats awesome that they featured your project. I'm sure that will inspire more people to build performance EVs.

Awesome Arlo! Looking forward to this build. Let me know if you need any CNC milling done, I would be happy to contribute to your build.

Yeah I should, sorry Paul I didn't mean for this to turn into a lengthy discussion on your thread. I was looking at surplus parts on ebay, but maybe its best that I avoid ebay. I know that its not going to be cheap or easy. I'll have to keep on doing research and experimenting. Hopefully...

I found some Infineon FF1400R12IP4 modules on eBay, would these work? Here's a datasheet...

I think might have misunderstood you in this post then. Your saying the IGBTs MPauls using are about half the power because there half the voltage, not because they have two transistors per module? I was interpreting it as that the way the manufactures rate them they add the capacity of the...

Would you be using 3 of double IGBTs? Wouldn't that be less power than your 6 800 amp singles? What about the game changer controller? You had talked about swapping the FETs a for IGBTs in your thread for a HV design. Are you building your next controller with large format IGBTs to get it up...

I am aware of the dangers of lipo batteries, I would need to be very cautious if I went that route. I see why your using 6 IGBT modules instead of 3 now. Since paralleling isn't a good idea and the double transistor modules are half the power maybe I ought to run 6 single transistor modules...

Thanks Arlo and SlowCo, I have been looking at Arlo's thread and there is a TON of good info there, I haven't gotten a chance to read it all yet. Why does your controller use 6 IGBTs rather than the 3 used in MPauls? I already have one of MPauls driver boards so I was going with his design...

Hi guys, I'm new to the forum. I'm planning on swapping a leaf motor in my 240sx this winter. I'm hoping to run the max power that the leaf motor is capable of using MPaul's control board. What do you think about running two of the 600A Powerex Igbt's in parallel? What other limitations do...
