I figure shorting a lithium-ion battery has fire potential, and with the battery living in the cabin, some precaution should be made. I might throw in a power resistor to limit current and then put a lower rated breaker or fuse for added safety. I'm not even sure if the 5Ah battery can supply 300A and trip the breaker. That's somewhere around 4,500 watts before the thing trips, assuming no voltage sag.
The test mule will be my Acura TSX.
I'll probably start a new thread if I get serious about this project, include some photos, a build description, and some data about various electrical draws that impact how long I can operate the car in "virtual alternator delete" mode.
Don't hold your breath; I have to find out where to live in a couple months, which might include buying a house. Lots of projects on my table, and I'm among the worst with time management (which is why I'm on here and not doing something useful).

you so crazy to use #10 with a 300amp breaker
or you just wanted a incandescent bulb under the hood?
you need at lest 4/0 wire for 300amp breaker (short run) longer runs will need 350 gauge wire(350 is a industrial sized wire)
trying to start a fire?
