Way too expensive, it's not anywhere near 'competitive'.
They're asking $899 for a very basic battery with no onboard monitor, and hitting you with another $10 for shipping.
My upcoming 'add-on' will have the same capacity, AND a monitor, for only $362 when it goes on sale March 27. Shipped free, all duties paid by them. I told them that I will be testing and throwing a fit if it isn't at least 92Ah, they said go ahead -and promised it will beat that by a large margin. (I own coulomb-counter meters.)
