In 1993, the first lithium-ion battery electric bike was launched in Japan. As the birthplace of electric bikes, electric bikes have enjoyed a high popularity in Japan. After the appearance of lithium-ion battery electric bikes, it was popular at home and abroad as well. Although electric bikes were introduced to China in the late 1990s, they did not catch on. At that time, the domestic technology level was still relatively backward, and the production of electric bikes needed to import high-cost parts. Most enterprises preferred to produce electric vehicles with lower technical requirements and costs, so the lead-acid battery with low manufacturing cost occupied much of electric vehicle batteries.

With the continuous development of economy and science and technology, the manufacturing of batteries of electric bikes in China has been significantly improved, and lithium-ion batteries have been widely used. At the same time, the debate about which battery is better, lithium or lead acid, is intensifying. In fact, both batteries have their own advantages and disadvantages. Although lead-acid battery technology is more mature and the price is more economical, it has poor low temperature resistance, short cycle life, and it does not support fast charging. Besides, Sulfuric acid and lead in the battery are easy to pollute environment. While lithium battery uses lithium metal or lithium alloy as electrode material, non-aqueous electrolyte solution, no heavy metals, so there is no pollution to the environment. At present, most electric bikes on the market use 18650 lithium battery cell, which has the characteristics of small size, light weight, large capacity, long life and stable working performance. Its energy density is generally about 140wh/ kg-160Wh /kg, which can support fast charging and have a long cycle life. But no matter how good the quality of the battery cell is, there will still be some errors between each battery cell after a long time, so BMS is needed to manage the charge and discharge of the battery, so as to reduce the damage and prolong the life of the battery during use.

Just the choice of battery has been so complex, such as the battery life, motor performance and controller professional should be considered, so choose a good electric power products really need to spend a lot of energy. But as to the LvBu ebike conversion kit, comprehending the needs of the majority of riding friends on the market, Lvbu launched a 3-minute electric bike conversion kit series, letting you quickly find the desired products. This electric bike kit includes a battery, a motor and a controller, and it can be quickly installed on the bike in 3 minutes, which is basically suitable for most bicycles on the market.

About the battery, the whole series of Lvbu electric bike kits are all using 18650 automotive power lithium ion class A cells. The capacity of a single battery can reach 3000 MA, even after charging and discharging 800-1000 times, it can also maintain 75% of the electricity, and the service life can be extended to 5-10 years. Moreover, Lvbu electric bike kit has a BMS protection system with wireless arrangement, which has six protection functions: over-charge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection and load balancing. In terms of battery safety, we strictly control it to ensure its safety, stability and waterproof, so that users can use it more confidently without worrying about risks such as explosion. Moreover, each series of Lvbu electric bike conversion kit has the same intelligent assist system, APP control, anti-theft alarm and other functions, while the mileage, appearance and configuration of different series have their own characteristics. For example, ebike conversion kit of KX series, integrates motor, electric control and battery in the wheel hub, simple installation, as long as the replacement of the original wheel, which is suitable for daily transport and grocery shopping with children. ebike conversion kit of KF series, the battery is a kettle type design, beautiful and compact, easy to take, medium mileage, which is suitable for daily commuting of office workers, or short-distance leisure riding. ebike conversion kit of KT series, the battery is a bag design, which is suitable for daily cycling training and weekend outing. And ebike conversion kit of BZ series, the battery is a rear shelf design with large capacity, assist range up to 180km, which is very suitable for long-distance riding.

At the same time, in the Lvbu micro-power APP, you can correct the gyroscope angle, set the vehicle weight and load, power mode, overspeed alarm, speed limit alarm, loss report, and firmware upgrade. On the home page of the APP, you can choose five power modes: commuting, leisure, manual, exercise and climbing, which basically cover most scenes of daily cycling. If you want to adjust the size of power at any time, directly switch to manual mode, support the adjustment of 0-99 power, the greater the value, the greater the power. 0 is no power, 99 is pure electric mode. What do you think of such a lithium-ion battery electric bike?
