I personally shy away from buying products from companies that intentionally use "clever" but misleading advertisement or labeling. But I bet lots O'people will actually believe they invented antigravity.

It's a really expensive battery with a fancy device to overcome a design weakness with the product.
It'd be cheaper to install a low-voltage circuit breaker on a conventional lead-acid battery.

Is a 4 lb. weight savings worth the extra cost? Sure, to some people. And that's what they should be selling: an expensive weight savings. But that's not really how it's marketed.

I just posted it for interest. I don't need batteries, yet.
Have 5 Shorai/chargers and finally broke the code on their instructions...a PITA.
Hope they'll last a while.
