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...

Higher voltages also have another benefit. Smaller conductors are required with less loss through voltage drop.
Yeah ... that of course makes a lot of electrical engineering/practical sense.

Batteries will be constructed of many small cells in series/parallel rather than just one large component.
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.
