Battery Disconnect

Racecar Battery Disconnect Switches With Alternator Circuit Cut or Basic 2 Pole Battery Disconnects are Installed In Every Racecar on Track Every Weekend. Modern electronics and complex ignition systems require more amperage than ever. Make sure your racecar battery disconnect is allowing every amp to you to provide maximum power. Multiple fuel pumps, electric radiator fans, brake blowers, diff cooling pump, cool shirt with helmet blower, and ignition boxes pull more amperage and require a more complex and robust battery disconnect switch.

Build your electrical system correctly now and enjoy years of trouble free racing.
