WarP 11 Helwig H60 Redtop Brush Kit
Hellwig H60 RedTop Split brush kit for Netgain Motors Warp 11 Motor.  This kit includes 8 Hellwig H60 brushes pre-radiused for the Netgain Warp 11 Commutator and 8 Nord-Lock zinc coated washers.

The H60 is about 2.5 times harder than the old National K49 brushes and features improved commutation due to the split brush design.  This is the ideal brush for street use. 

The new brushes feature four leads instead of two for higher current ability, a mylar sheith on each lead to avoid case shorts, and a closed terminal connection for maximum seating area. 

Lower carbon dust, longer life, better commutation.  These brushes improve your motor significantly.

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.
