Approximately 3 to 5 years.
The capacity of this lithium battery is 60*12=720WH=0.72KWH. Electric vehicles have a power consumption per 100 kilometers, basically 1.3~1.5KWH/100KM, so the theoretical driving distance is =0.72. KWH/1.3~1.5KWHX100KM=48~55KM.
However, the actual usage is affected by other factors such as human weight, road conditions and wind, power conversion efficiency, etc. The actual distance is about 70% of the theoretical distance, or 33.6 ~ 38.5. K.M.
Lithium battery life cycle: The normal life of a lithium battery is 300 cycles with a capacity retention rate of 80%, and a good battery can reach 500 cycles . After charging once a day, it can travel 25.5-30.8 km after one year of use. Normally it can be used for 3-5 years.

Precautions for using lithium batteries:
1. It is recommended to use the battery under temperature conditions of +5℃~+30℃ (preferably 25℃) High temperature will shorten the service life and low temperature capacity will reduce;
2. . Different brands, different capacities, different new and old batteries are strictly prohibited from mixed use;
3. Hydrogen gas will be produced during battery use, so keep away from fire sources and maintain ventilation to avoid explosion;
4. Please keep the environment clean and prevent excessive dust from causing a short circuit in the battery;
5. The battery should be recharged in time after being discharged. The battery will cause the battery capacity to be reduced or even damaged, so a suitable charger must be configured;
p>6. A UPS with a load ttoo light (like a 1 KVA UPS with a 150 VA load) can cause a deep discharge. battery, which should be avoided as much as possible; 7. Proper discharge will help activate the battery, if the mains power is not turned off for a long time, the battery should be discharged manually, 2-4 times per year. , and the existing charge can be used to discharge for 1/4 to 1/3 of the save time;
8. If the power is not turned off for a long time, the battery must be discharged manually; . The battery (UPS) used should be stored after charging, and the battery should be charged and discharged every six months. Generally, the battery is charged for about 4-10 hours and the battery works in the inverter state. for 2 to 3 minutes.
A 60 volt, 60 amp lithium battery can travel approximately 150 kilometers.
Lithium batteryur 60V60Ah electric vehicle, combined with an 800W motor, the speed of the electric vehicle is calculated at 35 kilometers/hour by calculation:
Current size = motor power/; rated voltage = 800W/60V≈13.3A, that is, the average operating current of electric vehicles is about 13.3A;
Driving time = battery capacity/average current = 60 Ah/13.3 A≈4.5 h, i.e. In other words, the theoretical driving time of electric vehicles is approximately 4.5 hours;
Mileage driving time = driving speed *Driving time = 35 km/h*4.5 h≈157 km, i.e. the theoretical range of an electric vehicle is approximately 157 kilometers
That is to say: an electric vehicle with a 60 V 60 Ah electric vehicle lithium battery and an 800 W motor has a theoretical range of approximately 157 kilometers.
Influencing factors
Lithium batteries can generally be charged and discharged300 to 500 times. It is better to partially discharge lithium batteries than to fully discharge them, and to avoid frequent full discharges. Once the battery leaves the production line, the clock starts ticking. Whether you use it or not, the lifespan of lithium batteries only lasts the first few years.
The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main cause of the decrease in battery capacity). Eventually, the cell's resistance reaches a point where, even though the battery is fully charged, it is unable to release the stored energy. The aging rate of lithium batteries is determined by temperature and state of charge. The table below illustrates the reduction in battery capacity for both settings.
