3.7V low temperature rechargeable li ion battery pack with high discharge.
low temperature batteries are these which can work under extremely low temperature environment, they can work well to support important power supply when other normal batteries can not.
Godenbattery can customize them with different voltage, capacity, sizes ,including OEM and ODM orders
According to different work environments, we have 2 types:
1. Civilian low temperature battery,-20℃ discharge at 0.2C with 90% capacity, -30℃ discharge at 0.2C with 85% capacity.
2. Special type low temperature battery,-40℃ discharge at 0.2C with 80% capacity,at 0.5C with 75% capacity, this is in mass production.
