I suppose asking Kobi for a working prototype is like asking a farmer to show you the milk inside a cow. 
The video I posted yesterday Kobi says that working with these big companies its confidential.
Like the PT Granda one where they are developing battries to suit. If they improve on the technoligy Ultracharge 70%- pt Granda 30% split. Thats my understanding please correct me if I'm dreaming.
The 28,000 batteries for Blitz if they meet specifications. Size, Shape etc This would be a good indication, ask the delivery boy next time you order a pizza hut pizza whos riding a Blitz Scooter.
I did see a video of the battery being tested on a voltmeter testing at 4.7 sure if you look hard enough and through enough old footage you will find it. Might even be on their website, This talk is worth a listen. From August 30 2018
