My concern here is with the point of this thread.
Will lithium EVER be cost effective?
It isn't the battery. It's the cost of integral cell energy management. I look at the stuff I get from China - electronic parts and accessories with spiderweb tiny conductors wall USB chargers that quit (4) in the last month and they were not cheap.
I am not ever going to even consider spending five thousand dollars for a made in USA lithium battery bank when nine hundred dollars will give me the same amount of energy in AGM form. The shortcomings of AGM are minuscule compared to the shortcomings (vulnerability) of Lithium
I fear that energy project in Australia is a microcosm of what hyperbole is associated with lithium - money and value is the object especially the latter.
I'll say this again...
When ONE MILLION same type lithium batteries hit the road and SEVEN years pass, there will be legitimate customer feedback. It's much like the pharmacological industry. REVOLUTIONARY NEW MEDICATION INTRODUCED. Time passes. Suddenly an unforeseen crisis evolves. Efficacy, side-effects. Who cares. But in the case of the battery "3,650 days of dosage" has been spent.
Maybe later...
