The BCA Float E2 25 Turbo Airbag Pack is sweet new upgrade to BCA’s line of snowmobile-specific airbag packs. The key addition to this one is their new E2 engine. The E2 is powered by a supercapacitor, which despite sounding like a rare weapon from Halo, is actually a real thing. A supercapacitor basically is a really awesome battery. It performs better in cold temps, releases energy faster, and is much lighter and smaller than traditional rechargeable batteries. All of which, of course, is perfect for something you need to carry around in the cold with the hopes of never using, while requiring perfect, instantaneous response when you need to. Other than the new supercapacitor, the Float E2 25 Turbo remains a perfectly kitted sled pack, full of all the features you need for brappin’ about.
