Rule book says (8.1) Batteries may not be located in driver or passenger compartment.
If I were going to try to get away with it or your tech guys don't care, I would at least put it in a sealed, vented container like Moroso sells and make sure it is properly restrained so it doesn't come lose in the event of an accident.
If the results don't match the theory, change the theory.

Now, in certain cases the Li-ion battery itself blows or burns up. Yeah, just ask Boeing.

The battery should be vented to outside the body. If overcharged the standard lead-acid battery can produce hydrogen with explosive results.
A lithium ion battery contains no water, AFAIK, and cannot produce hydrogen. Now, in certain cases the Li-ion battery itself blows or burns up. Will the NHRA start approving these batteries for in-cab use?
R. I doubt it. Grays about burnt a Pro Stocker to the ground earlier this year because of one.

When I was meeting with Jim Bongard, the NHRA Tech inspector for our area to get my cage recertified, I asked him if I could mount a lithium ion battery in the cab. He said no. so I mounted it on the in side frame rail, is close to the starter as I could get it.

Thank you all for your input. I did further read the current series of THREADS here regarding Lithium batteries and am leaning toward these antigravity AND yes installing it below the floor boards. these appear to be 12v...Joel, could you physically measure LxWxH of your street rod batt please? ALSO someone posted a good LINK in WhteDarts Thread about new developing battery technology...in this they explain the worse cause of lithium battery degradation to be a rapid recharging rate...in the meantime before these 'tolerant' batteries are produced...HOW does a bracket racer with an alternator and pit charger replenish a battery at an acceptable rate? I charge my 12 volt Diehard platinum battery at home with a trickle charger MAYBE 1-2 times a month. 60 amp one wire alternator used at all times while racing.

Best thing to do is buy the battery and charger from the manufacturer. Lithium batteries require less voltage to charge at typically .7-1.1 volts less than their lead acid/AGM counterparts. Most all lithium manufactures list the max charge voltage and rate for their batteries. For instance my AGM 16V charger like we use in the Dragster charges at almost 19 volts, my Lithium one maxes out at 18.2

Before alternators came into fashion on race cars, it was common to run 2 batteries to avoid problems in late rounds after a long day. A lot of Stockers still do since they have to run a battery in the stock location anyway,

What I'm looking at doing is dropping in a very small metal battery box next to the frame rail on the passenger side floor.. with a Zeus fastened cover.. my lithium battery is only about the size of a quart of oil. technically the battery would not be in the passenger compartment.. but it would be accessed through the passenger compartment

I would like to use my alt but there should be a way to regulate the recharging amperage?
