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...

What on Earth is so "special" about 48 volts for average use in the average RV???
Use in EVs for their drive motors is one thing, use in RVs for routine camping use is another thing.
IMHO, what the RV world needs is lithium (or some other technology) based batteries that pack a lot more energy into the SAME FORM FACTORS as good old lead acid based batteries have come in for decades - whether it be 6V golf cart battery sizes or 12V Group XX battery sizes. When are drop-in new technology batteries in these sizes coming at affordable prices?
(I suspect that most of the new battery technology development money is aimed at lower resistance losses during the periodic high current drains required in electric vehicle applications ... hence 48 volt and higher new technology battery packs. As usual - "follow the money".)
What's the benefit to replicating the lead acid form factor of bulky boxes? One of the great benefits of a lithium ion cell pack is it can be made into almost any shape. Fit the pack into the empty spaces around the water tank under the bed, or in that void under the fridge, or curved packs that fit over the wheel humps. You won't need to touch 'em for 15+ years, so they don't need to be super accessible.
Electric vehicles don't use 48 volt packs, those packs are in the 100s of volts. 48 volt packs are mainly for PV applications, and things like bicycles or those unicycle things.
