Show Me Your Battery Kill Switch

Okay, whew! I just looked up the battery relocation rules in the NHRA rulebook, and here's what it says in rule 8:1:

"All batteries must be securely mounted. Must be of sufficient
capacity to start vehicle at any time. Batteries may not be relocated
into the driver or passenger compartments. Rear firewall of .024-
inch steel or .032-inch aluminum (including package tray) required
when battery is relocated in trunk. In lieu of rear firewall, battery
may be located in a sealed .024-inch-steel, .032-inch-aluminum, or
NHRA-accepted poly box. If sealed box is used in lieu of rear
firewall, box may not be used to secure battery and must be
vented outside of body. Relocated battery(s) must be fastened to
frame or frame structure with a minimum of two 3/8-inch-diameter
bolts. (“J” hooks prohibited or must have open end welded shut.)
OEM-located batteries without complete OEM hold-down hardware
must be secured to OEM battery box/tray using the same 3/8-inchdiameter-
bolt hold-down method described in previous sentence.
Metal battery hold-down straps mandatory. Strapping tape
prohibited."

So I guess a battery box can be used instead of a rear firewall. :cheers:
