NHRA Rules and Battery Relocation

The NHRA requires that any vehicle with a relocated battery must have a master disconnect switch installed on the exterior of the vehicle. SCCA rules are reportedly similar.

found that at battery relocation

Not sure but I think the battery has to be separated from the drivers compartment; in other words, in the trunk. Also, a sealed battery box bolted down and vented to the outside. kill switch, fused???
Hopefully someone has the latest rules. It also depends on the class you run in as some classes don't even allow it.

Here you go.

8.1 BATTERIES

All batteries must be securely mounted and may not be relocated into the driver or passenger compartments. Rear firewall of .024-inch (.6 mm) steel or .032-inch (.8 mm) aluminum (including package tray) required when battery is re-located in trunk. In lieu of rear firewall, battery may be located in a sealed .024-inch (.6 mm) or .032-inch (.8 mm) aluminum, or FIA 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. Strapping tape prohibited. A maximum of two automobile batteries, or 150 pounds (68 kg) combined maximum weight (unless otherwise specified in Class Requirements) is permitted. Metal battery hold-down straps mandatory. Hold-down bolts must be minimum 3/8-inch (9.53 mm) if battery is relocated from stock and other than stock hold-downs are used ("J" hooks prohibited or must have open end welded shut.).
