3.65V 6AH LiFePO4 Cell with Long Life and High Capacity,H 70.5 X D32.4 X W10.5
HRESYS VHR 32700LFP-6.0AH lithium iron phosphate battery adopts mature cylindrical battery production process, which has the advantages of low calorific value, non-thermal charge-discharge battery and low internal resistance. Charging and discharging capacity gap is only 0.5%, electricity is basically absorbed and rarely into heat. Its charge-discharge curve is very flat (at least 80%) and fluctuates within a stable 0.1V voltage difference over a long period of time. Charging generally adopts constant current charging to constant voltage mode, it can also be charged and discharged according to customer's needs. The whole system has the characteristics of high energy density, small size and light weight. It is suitable for small-scale energy storage, commercial and industrial energy storage, electric motorcycle and electric bicycle.
1. High volumetric energy density ratio, the equivalent volume is more than 5% higher than the conventional lithium iron phosphate battery capacity;
2. Long cycle life, more than 2000 cycles;
3. Low calorific value. The cylindrical lithium iron phosphate battery has the characteristics of low calorific value and low temperature rise;
4. Low self-consumption and can be stored for a long time;
5. High energy conversion efficiency, reducing loss during energy charging and discharging;
