New Moto Guzzi Door Mats Available Now
Personally, I don't get it. You could tap into the motorcycle battery. With care, and a voltmeter to monitor it, any system can tolerate that load. I just don't want to carry that huge brick on my body, for just the short few hours you get.
I work outside in WNY winters. The battery operated stuff is marginal for work and does not last nearly long enough. I can't use it on the bike-just not enough performance. The gloves with batteries are even worse-really, useless. Bought some high end ones and they are way too bulky, battery life is short, even on high not warm enough die to uneven heat, etc. YMMV.
the 12v battery stuff turns riding in the cold into a whole new and fantastic thing.
Wayne -- the LFP battery weighs 1.5lbs which is three times the Ororo vest battery's 0.5lbs.
