Re: "Apple is examining a chemistry for the car battery called LFP, or lithium iron phosphate, for its car", that will bring the cost down for all of us
I don't know how the cost could come down too much more... I got 600AH at 24V for $3600. The only thing I regret is not getting one more battery so I would have 900AH at 24V.
The price has come down so much that in Thailand it is more expensive to get AGM batteries than LiFePO4.
