If I need to lock it in by September should I just pay the $30 more and get it before it's $300/325 again?
Any huge breakthroughs I'm missing about to drop the price of LiFePo4?

NO> These are great replacements for deep-cycle Camper, home Solar and such. Not meant as a starter battery, but a huge storage of energy. Plus your Alternator isn't designed to charge these and will most likely destroy it. I snagged one back when it was $208. It is nearly 3 x 1 Walmart 29DC battery. So far It is doing great in my small camper. Had to install a cutoff breaker to keep the shore power and Alternator of my truck from damaging it.
