Must take a lot of energy to charge the battery in such a short amount of time. Wouldn't want one of these battery's blowing up that's for sure. With that much energy stored in it it's got to be like a large capacitor especially when it only takes 5 to 8 minutes and on your way again. In a Electric Substation they have large capacitor banks to control the line voltage. You don't want to be in the Substation when they close them into a hot line. If they are gong to fail that's when it usually happens. Fortunately it happened once in one of are smaller Substations thank God no one was there at the time. Would be nice to look at some of there patents before investing in this company. This is a big deal and could be life changing. Now this battery could make Oil Obsolete. We will still need Oil but will definitely use less and change the world as we no it.
