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.
It's something about the physics of how a lithium *whatever* type battery works, it does not scale up well in amperage. however, many batteries are like this... lead acid is no different. a 12v lead is really a "pack" with six cells mechanically interconnected. a 9v battery also a "pack" with six cells inside it.
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.
