Best Battery Clamps for use with 4/0 AWG Copper wire and loads of 1,300 watts continous?

Hi Guys!

Brock just gave me a great idea for my inverter set up that I have in mind. He suggested battery clamps (Crocodile clamps/Jumper Cable Clamps?) instead of ring terminals /w Anderson Connectors. I think if this can be done it would be a better approach for my set up since I feel much more comfortable using jumper cables than the Anderson Connectors; plus I plan on moving to a different electric car in a few months so it would save on re-installation/rewiring.

This is what I currently have:

The inverter:  Xantrex prowatt sw2000 (1800W continuous 3000 Max Surge)

Blue Sea Systems 5191 Fuse Block Terminal 30-300 AMP 
http://www.amazon.com/Blue-Sea-Systems-250A-Terminal/dp/B0026KY6R0
Blue Sea Systems 250 AMP MRBF Terminal Fuse
Anderson SB350 Connector up to 450 Amps

Copper Cables: #4/0 AWG <--- I still need to buy the cables..... and now I need the Battery Clamps....

So I will basically not need the Anderson connectors. I don't know if the Fuse & Fuse Terminal can be used with this new approach of using Battery Clamps instead of the Anderson Connectors. Brock suggested that I still use a Fuse on the positive cable just to stay safe.

What type of fuse will I need for this set up to replace the 250 AMP fuse and terminal? Do I need a special type of fuse? Or can the fuse that I have now just dangle around?....

Something else I am worried about is the Battery Clamps not clamping well enough? There seem to be a lot of different shapes for the Battery Clamps (Jumper Clamps?) and I was wondering what is the best shape for use with the positive Terminal on the battery? I see some with teeth others no teeth. Some more curved others more flat, etc. My battery has SAE Terminal Posts, but it already has a battery clamp (From the car) so this Battery Clamp I will use with the 4/0 cable would have to go over the car's battery clamp.

Here is a pic of my car's battery clamp.




For the negative connection I will be using the Battery Clamp (Crocodile Clamp?) on the car's Chassis ground because the negative terminal on the battery has a sensor that you aren't supposed to clip anything to.

Then basically on the other end that goes to the inverter I will just have regular ring terminals which is what the inverter needs. The Battery Clamps just sound so much easier to use than the anderson connectors plus easier to set up and can be used on other vehicles also which I think will be quite handy.

The main thing I will run with the inverter is an induction cooker that has different cook settings. I feel I will likely draw around 1,000 watts to 1,300 watts while using the induction cooker... but it can draw more though I doubt I will use the higher settings. The car is electric and can provide the needed power (as far as I have read). I will also use a blender sometimes, but the power requirements on it is only a fraction of what the induction cooker needs so it should be fine.

Uhm.. anything else I should be worried about or that I might also need to buy? I'm a total noob as you guys probably already noticed...

Thank you!
