Na, otherwise you wouldnt see so many hatchback stangs with the battery in the trunk, but you have to run a master battery cut off switch

NHRA handbook:

"Mandatory on any car with a battery running a 9.99 or quicker, or any car exceeding 135mph or on any car where the battery has been relocated into the trunk area."

It does not have to be in an actual trunk. It can be in a hatch with a Moroso "blue" battery box, or if you use ANY other battery box you must use have a firewall/bulkhead in the hatch. Anexample of the firewall can be seen here:

Any car with a relocated battery must be equipped with a master electrical cutoff, capable of stopping all electrical functions including ignition (must shut the engine off, as well as fuel pumps, etc.). The switch must be located on the rear of the vehicle, with the "off" position clearly marked. If the switch is of a "push / pull" type, then "push" must be the motion that shuts off the switch, and plastic or "keyed" typed switches are prohibited. Also, the battery must be completely sealed from the driver and/or driver compartment. This means a metal bulkhead must separate the trunk from the driver compartment, ******or***** the battery must be located in a sealed, metal box constructed of minimum .024 inch steel or .032 inch aluminum, or in an NHRA accepted plastic box. In cars with a conventional trunk, metal can simply be installed behind the rear seat and under the package tray to effectively seal the battery off from the driver. In a ******hatchback****** type vehicle the battery box is usually the easiest solution, since the alternative is to fabricate a bulkhead which seals to the hatch when closed. At present, Moroso is the only company which offers an NHRA accepted plastic battery box, part number 74050
