If I want to use a lighter weight Braile 3121 in the trunk with the flaming river exterior cutoff switch and have it be NHRA legal, does it need to be in a sealed and vented box like a Taylor 48101 or can it be placed into something like an AFCO Battery Box part# AFC-50302?

The Braile 3121 is gel battery but it still produces gasses and therefore I would think that it needs to be in a sealed box and vented to the outside since the 4th gen's have an open trunk and no rear firewall. Also the box needs mounted to the frame rail with 3/8" or larger hardware?

It need to be in a box regardless of battery type.
