So I know that Lithium batteries are really great for car audio for a lot of reasons…

But if a Lithium battery is rated at, lets just say 45 ah, wouldn’t an AGM rated at 90 ah have twice the reserve power of said Lithium ?

Honestly, I’m still trying to imagine any reason why more amp hours (reserve) would help me anyway ? I never play the stereo with the truck not running, and I’m making more power continuously, than the stereo uses at peak power…. except super fast little spikes…

Amp hours ?
