Advantages for lipo batteries:
1.Stable discharge, low internal resistance, fast charging time;
2.Long battery charge and discharge cycle life, low self-consumption, high safety performance, and can be recycled for more than 300 times;
3.Green and environmentally friendly, does not contain mercury, cadmium, lead and other harmful substances;
4.Conventional battery operating temperature: - 10℃℃~60℃℃;
5.Safety protection: overcharge, over discharge, over current, short circuit protection: can be customized according to customer requirements;
6.Using the latest 4.2V/4.35V high-energy battery, and using advanced battery management system to provide sufficient power, continuous working current can reach 10C-15C, etc.;
7.High temperature performance battery: high temperature 70℃ for 24h volume change rate 8%, 85℃ for 48 hours fully charged battery does not catch fire, does not explode.
8.Low temperature performance battery: low temperature -20℃℃, 0.2C discharge greater than 95% initial capacity -20℃, low temperature -40℃8.0.2C discharge capacity>80% or more low temperature cycle performance outstanding, can achieve 0.2C charge and discharge cycle 300 weeks capacity retention rate of more than 80%, special technology multiplier type low temperature lithium battery can increase the low temperature -40 degrees 0.2C discharge to 1C.
