Electric bicycle with lithium-ion battery "applies to all types of electric bicycles. The product can reach the battery in the battery pack is automatically monitored to ensure that the battery is safe and reliable in application. This product has the characteristics of small size, light weight, long life. 

 Light weight, small size 

 Total weight, volume is 1/3 of the lead-acid batteries of the same specification, whether it is the elderly, women, or children can be easily moved. 

 Low temperature 

 Ordinary lead-acid battery is below 0 ℃, charge less than 50% of, Di crystal lithium-ion battery can still emit more than 90 percent of electricity at -20 ° C at -40 ° C can still emit more than 80 percent of electricity. 

 Long life 

 Di crystal energy lithium-ion battery charge and discharge times in the practical application of more than 1000 times its capacity of not less than 80% of its original capacity, lead-acid battery after 200 charge and discharge capacity of only the remaining 60%. 

 Green 

 The lithium-ion battery leakage, non-polluting, such as cadmium, mercury, lead and heavy metal pollution problems have been resolved in the manufacturing and use of the whole process, is a globally recognized green energy. 

 Powerful 

 Di crystal lithium-ion battery monomer internal resistance is greater than 6mΩ internal resistance of the battery pack is not greater than 80mΩ, the start and climbing, and other high-current case, the battery pack can provide higher power, climbing higher, accelerate faster.
