New LG lithium batteries $600 per KWH
LG has a new line of lithium batteries out, and the rumor is they are 600$ per KWH. I am surprised no one on here has mentioned the newer LG Chem RESU lithium ion batteries. They have managed to pac...

That bothers me and is not necessarily good 48V sense. What is it with lithium technology that prevents large capacity single lithium cells? Maybe some technology expert can explain the issues with, say, building a 600 AH single 3.7V lithium cell so that only 13 of them in series are needed to make a 600 AH 48V lithium battery pack?
A lot of small cells means a lot of mechanical inter-connections. Mechanical inter-connections are a classic weak point in complex systems ... unless those connections are solid-state connections like the ones embedded within semiconductor components.
I like the idea of having hundreds or thousands of cells inside a battery pack. If a few go bad, no big deal. If a cell in a lead battery goes dead, you throw the entire thing out for recycling.
Nothing limits large capacity cells, only demand.
there is nothing difficult in assembling a large multi cell pack..
3.2V 1000 AH cells are readily available. issue is cost. $1200 USD each... so that's approx $18,000 for a 48V 1000Ah pack.. some people here don't even spend that much on an RV !!
If a few go bad.. well that's fine if there are protection mechanisms in place. if not and one explodes or shorts then you are big trouble..
like I said elsewhere in this thread.. the issue is with panel efficiency not battery storage.
