Can You Model The Tesla 18650 Lithium-ion Battery Pack For Electric Motorcycle Bikes, And How Does The Cost Compare To Lead-acid Batteries?

Can You Model The Tesla 18650 Lithium-ion Battery Pack For Electric Motorcycle Bikes, And How Does The Cost Compare To Lead-acid Batteries?

There are some on Taobao, most of which are packaged batteries. Tesla's core technology is in battery management software, and this is no way for itself. More reliable on electric bicycles is the assembly of 26650 batteries with lithium iron phosphate. This safety is much better than that of lithium-ion batteries. The disadvantages are low voltage and low energy density. With 26650 lithium iron phosphate, a123, 2200mAh, the price of Taobao is about 20 yuan (I don't know if it is fake). The voltage is 3.3V. A typical 48V battery pack requires 12 sections in series. To achieve 11Ah requires 5 groups of parallel, a total of 60 knots, 1,200 yuan. This is not a battery protection board or a balanced charger. It is more than three times the price of lead-acid batteries of the same capacity. Of course, the internal resistance of the lithium battery output is very small, and the starting power is sufficient. The nominal cycle is 2000 times, which is 4 times that of lead-acid batteries. The long-term cost-effectiveness is still better than lead-acid batteries. As for the aluminum-clad battery, there is no manufacturing standard so far, and it is more likely to be shoddy, and the safety is obviously not as good as the 18650 and 26650 batteries of the steel case.
