Down4Sound Vs Big Jeff audio lithium car audio battery comparison test D4S LTO 6.0 Big Jeff 22ah

Checking out 2 of the smallest car audio Lithium batteries form Big jeff Audio and Down4Sound.
All battery manufacturers rate the max amperage output of batteries at 7.2 to 8v. NO companies rate the output at 12v. I provide 2 tests for reference but the 10v is more relevent and even higher than the manufacturers max output voltage. But for car audio I see no sense in testing at 7.2 or 8v as car audio that is too low.
