Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

I'm as confused as some of you:
Take four(4) 12 volt stand-alone drop-in-replacement-for-liquid-acid lithium batteries - each with their own internal individual cell balancing circuitry inside each 12 volt battery's case - and wire them together in parallel in a balanced cabling resistance buss or harness (how to do this has been discussed many times in these fourms).
Now apply an RV load or an RV charging voltage to the buss or harness. Each battery would then wind up with identical voltage on it's terminals. What then is to keep each battery's internal circuitry from properly balancing and/or otherwise taking proper care of each individual Li cell inside the 12 volt battery? The four(4) batteries being wired together using a balanced cabling or buss arrangement will insure balance at all times between the main batteries.
Something doesn't smell right here.
