Also in hand...

I've received my NetGain cover band. As you can see, it's all bent and warped. The duct port isn't even curved where it meets the band so it pulls that area out of round. So much for made in America. Let's hope after I modify it that it does the job. They charge $65 for this thing.I also got my diode and inductor from EVTV. These go with the Chennic DC-DC converter and should make it a more reliable unit.

Puzzle Pieces

Here's the cooling solution I'm going to attempt to implement for my Warp 9 motor. It's a Jabsco 150 CFM blower with a washable air filter directly mounted to it. At first, I had planned on mounting this combo directly to the Warp 9 via the NetGain cover band (which has been ordered but has not arrived yet). However, there is some significant weight involved and so I think mounting it to the chassis would be best and I'll use some ducting to direct the cool air into the cover band.Next up are some bits I received from Jack Rickard and the folks over at EVTV. On the left is a heavy-duty maintenance switch that I will try to install in a convenient place to disconnect the HV battery pack from the equipment under the hood. It's certainly not meant to replace a circuit breaker for emergency disconnects under load, but I'm hoping it can carry 192V across it without any issues. We'll see. On the right is a Chennic 400W DC-DC Converter for supplying the 12V system. A diode and inductor are on the way that should make this a reliable converter. It's a lot smaller than I thought it was going to be. Likewise, the switch was larger than I had expected.Above you can see the back of the switch. The terminals are beefy enough to accept 4/0 cable and lugs (according to the specs) and the whole assembly feels solid. I'll have to work on some more brackets/mounts to start installing all of these components where I have space under the hood. It's like a great big puzzle.
