I've left the fan and water pump on for a couple hours (twice in one weekend lol) dragging them down to 20-30% and they charge right back up. The ones in the car now are from 2020 so I'll replace over the winter.

Had a 17 pound braille in the nova, even fully charged up it would struggle. So I can see where 2 11lbs plus a alternator would be about as low as you could safely go with AGM. I swapped out the Braille for a 12V Lithium(with BMS) and it likes it 100% more, and dropped over 11 pounds, but its a lithium so not for everyone.

In my bracket car I ran 1 optima and 1 motorcycle battery (11lb) with alternator. Didn't know if it would work. 2 seasons later motorcycle battery gave up.
But be a stocker is the correct size battery need to be in stock location?

Iv'e been running a single 11 lb. Braille 12v lithium with an alternator for years. No issues .

I've been using 2 of the Odyssey batteries with no issues. They are 2 years old now. Keep a maintainer on them and only charge at low amps. Not crazy about lithium ion batteries.
