    1. Our battery can be used well below 0C (can be normally discharged), but we don’t suggest charging the battery below 0C.
      It is like most kinds of the battery in the market now:
      Operating Temperature: Charge: 0°C--50°C; Discharge: -20°C--60°C.
      Currently our battery can be charged at low temperature, but it is charged with a very small charging current. And we’ve used auto motive grade battery cells which have superior quality. Even if charging in low temperature environment for emergency usage, it will not damage the battery.
      We're planning to sell batteries with self-heating functions which allows it to be charged in freezing temps in a few months, and you could keep an eye on our store if you're interested.
