Ok you have investors, What stock exchange are you listed on and what are you listed as? And once again how are the inverters for the drive motors in a tight turn controlled. You are still off on the price of the LI battery. By the way a certain company has tested a hydrogen fuel cell/ LI battery pack The fuel cell is under a constant small load instead of full on/ full off mode of operation keeping the li fully charged. Acts like a accumulator in a hydraulic system.
