Anyone use something like this between your battery and main battery cable?
I'm sure 150 amps is not enough for a starter motor..... or is it?

I also thought these were interesting too.

That's why I put a starter solenoid (think ford style, but it came from Jegs and is slightly different) in the rear to fire my starter and then ran a second battery cable up front with a circuit breaker on it to protect the wire that feeds the rest of the car. You don't have a fuse on the starter, but the "hot" lead is only 12-14" long when the car isn't cranking. Everything else is protected (remote master solenoids to seperate off the alternator to avoid problems with the ignition back feeding when the master is killed and a second one for the master (you could skip those if you like, but I stand by using a starter solenoid in the rear).

Jegs has their own version that's less money, but basically this is the same unit I used:

My breakers came from here:

The remote master solenoids I used are from Painless:
