Let me bore you to death here.? In the telecommunications world, 48 volts was/became the standard for telecommunications central office equipment decades ago.? This allowed for simpler battery backup systems. This was the voltage running on POTS (plain old telephone service) lines to houses and businesses. ? This standard spread worldwide.? More recently, when telephones were migrating to packet, IP, data interfaces, and there was a need to power the telephones and other equipment without using the dreaded "bricks", 48 volts was the selected standard, again worldwide.?

I'd thought that this voltage standard would move to the electric car arena, because of the desire to control powered devices with data packets; that using data network interfaces would allow manufactures to use more "off the shelf" technology.? Hasn't happened yet.?? It appears some will skip network over wire and go to wireless interfaces instead.?

Anyway, yes, there needs to be standardization. ? Usually, that means that the most successful vendor eventually drives an industry to their standard? (The Bell System and Cisco being the vendors in telecom). ??? I think the Black and Decker conglomerate could do this.? But maybe it is not in their interest, if they're making all their money on proprietary batteries. ? ? Wait for the lawsuits as the Chinese battery manufacturers start selling knockoffs- since they're making most of the lithium batteries and tools anyway. ?

Also interesting or weird in this space are Tesla electric motors.? Apparently, Tesla makes these for under $800.? Yet they sell for $3-4K used.? Should be an economic opportunity for someone.
