Black gold batteries are also lead acid batteries with a charging time of 300 to 500 times. If they are discharged with high current and used for less than a year, they will be scrapped, for example for transporting goods. I have been making lithium batteries for ten years. In conclusion, the larger the capacity of the lithium battery, the lower the operating current, and the longer the life of the lithium battery I made from car electric cells is more than 2000. times, and it can be used for five or six years when charged daily. Therefore, choosing a power lithium battery is the first choice when purchasing, inquire about the internal resistance, capacity, discharge coefficient, warranty and other parameters.
Emma's original battery is black gold. The batteries of Emma's electric vehicles are mainlyent lithium batteries and lead acid batteries, and Emma's original batteries are mainly black gold. Emma's new Shenma series of electric vehicles are all equipped with Chaowei black gold batteries. It can still be used for 2 years after the warranty period. Currently, a large-scale process of replacing lead-acid batteries with lithium batteries has begun, and attempts are being made to use a new updated technology - graphene technology batteries. The initial battery capacity is increased by 10%, the maximum power. is increased by 16% and the low temperature discharge time is increased by 18%. Lifespan is increased by 90%.
