Lithiun Ion Battery Caution

Been looking at the Braille Battery website. I am not impressed, maybe its my browser or Im old but I could not find any downloads on their download link.

I get the feeling they expect the battery to be the sole power source during use. I can see how you could add a battery charger and have the alternator / generator power a LI battery charger as two separate systems NOT connected together..

I'm not sold on the Tech just yet for traditional auto batteries.
