Giving them terrible efficiency. That's almost 50%. Given that an electron-in to charge at 70 volts comes out at 36 volts is a 50% loss of "power" and hence efficiency. Such batteries are great for standby back up systems where efficiency is of no concern. But for a daily solar cycle, adds another 50% loss factor on top of an already abisymal 30% performance per dollar.
