I profess I didn't look at the financial side before this in any detail --- but, I didn't realise that SA had to pay for the power that is stored then used in the Telsa battery in SA
?????
How odd --- I hope I don't have a looming invoice coming from Duracell for the power I have used in all those AA's I have purchased over the years.
Doesn't sound like a cheap alternative to me --- when, you have to pay for the battery, pay for the power you put into it, pay for the power you pull out of it, pay for the maint. (I assume), and pay to replace it in future.
