Battery performance in the cold: The 36 to 42 hour flasher operation time in our specifications is based on a cold-soak of 12-hours, and then 36 to 42 hours of cold operation at near 0-degree F temperatures, at a 200ma power draw. This is without the use of GPS or LCD screen.

The technology inside the Featherlight is the same battery tech found inside lithium augers (Strikemaster and Ion for example), Milwaukee/Dewalt power drills, and Tesla Autos. These products/brands are utilizing Lithium-ion in the cold and are not using LiFEPO4 or SLA.

Weight comparison: A comparable sealed lead acid (SLA) at 7.5 Ah is ~7lbs. A 7Ah LiFePO4 competitor on Amazon lists their weight at 2.24 lb. so comparable 7.5Ah is going to weigh in at ~2.5lb.

So they’re ~40-50% lighter than LiFEPO4 (depending on brand) and +80% lighter than lead acid. So it’s light wnough to really surprise you.

What is a LiFEPO4 battery: a really good read up on how to decipher the differences in battery makeups can be found here: http://www.cobox-ebikes.com/296/basic-understanding-of-lipo-li-ion-and-lifepo4.html

Please keep in mind that though that this write up says you need a special charger, when ours do not.

As for the $109 price. We will only be running that for a week or two longer (no set date yet).

Lithium-ion. A different technology then LiFePO4.

Hey guys. Rep from Norsk Fishing here to answer any questions if you have them.

On the topic of chargers: Our lithium battery is designed such that you can use your old charger. This should allow you to recharge fully in 3-5 hours. We are working on designing our own charger, though, so charge indicators align with our operating voltage and so people don’t feel uneasy about using an old charger.
