Gigavac GX110 1000 Ampere Contactor
1 of 5
 GIGAVAC GX110 1000 AMP CONTACTOR RELAY
This is the highest power contactor relay we have found.  It will do 1000 amperes of current continuously at up to 800volts and 5000 amperes for up to 10 seconds.  It is overkill for most electric vehicle builds but for the ultimate in safety and power switching capability, this is the 800 lb gorilla.

Relay is normally open.  Coil powered by 12v.  Draws up to 5.6 amps to close but holds position with 1.3 amps at 12v.  No coil suppression diodes required as internal coil suppression is provided.

The ultimate contactor.  We haven't found anything larger.

1 Rebling7009 Hi Temp Receptacle and Mating T Handle Connector
1 of 8
 Rebling 7009 high temperature 500F receptacle and gasket is the female battery connector for your next battery box.  Carries 750 amps of continous current or up to 1500 amperes peak. It has a lower resistance solid terminal post than the 7002 series and a much higher temperature resistance. The Rebling 7016-1 T-handle plug is ideal for cable terminals up to 3/0.

Rebling plastics has developed a line of high quality high current milspec battery connectors used primarily in aviation applications.  Pricey, but extremely safe and extremely durable, these will last in electric vehicles for years providing a very low resistance high current connection with the convenience of a half-turn handle to disconnect the pack.
