With technology development, lithium battery and people life are inseparable, lithium battery has been used in a large number of electric vehicles, including the electric bike.
Advantage of Lithium-ion Batteries
Li-ion battery is more powerful than lead-acid battery at the initial stage; The weight of the same capacity is about 1/2-1/3 of lead-acid batteries; Lithium battery has a wide usage temperature range than lead-acid battery; The cycle life of lithium battery is 2-3 times than lead-acid battery; Lithium battery without harmful heavy metals to the human body, the human living environment more friendly, more environmental friendly.
What should customers consider?
When selecting e-bike batteries, we should first consider the E-bike voltage platform, use, cycling road conditions, and the driving mileage.
For example, A 36-volt controller and motor, in general, requires a 36-volt pack. All controllers allow a range of voltages before they pop so it’s highly probable you could go to a 52-volt battery even though your controller is rated for 48 volts. By over-voltage your 48V controller and motor with a 52V battery, you get a nice performance gain with a low chance of your controller. Upping the voltage of your battery slightly is the easiest way to get a performance gain on an existing electric bike set up.
After the voltage is determined, Smartpropel develops battery products for electric bicycle, it will make precise positioning according to the use of the products, cycling environment. Configure different capacity of lithium batteries according to different positioning.
2.The use of an E-bike
For the electric bike, the general use is divided into daily or called urban mobility, suburban leisure and entertainment, sports and fitness, land exploration, cross-country exploration, and mountain conquest, and so on.
Different usage scenario requires different motor, controller and lithium battery.
3.Cycling road condition
There will be flat paved roads, undulating countryside terrain, mixed roads, mountain trails, and steep climbing trails.It is easy to understand that if the road is steep and bumpy, in order to reach the same speed and drive range, should need larger battery pack.
How to select the right lithium battery capacity?
For example, the electric bike on the South Sichuan Tibet line, which is suitable for all-terrain cycling, requires a lot of torque to overcome the harsh and complicated road surface and has a long-range, so the configuration of a larger capacity 576Wh light efficient lithium battery. Range: Sport: 80-100 Km; Normal: 100-120 Km; Eco: 200-240 km, which is just what you need for a planned daily cycle of about 200 km.
Of course, it is necessary to bring a spare battery to the South Sichuan-Tibet line, which is the most difficult drive road in the eyes of cycling enthusiasts.
Equipped with 432Wh lightweight high-efficiency lithium battery, Sports E-bike can support you for urban mobility, range parameters: Sport: 40-50Km; Normal: 50-60Km; Eco: 100-120Km, this parameter can be adjusted when the power-up mode in SPORT, the instant release of a strong 80Nm Torque to meet the needs of hill climbing race.
An E-bike with a 360Wh light-weight high-efficiency lithium battery is a good choice for leisure. Its excellent cost performance can meet the use of long-distance leisure riding, the original car configuration range: Sport: 30-40 Km; Normal: 40-60 Km; Eco: 60-80 km.
One more thing I have to mention, not the higher capacity, the better. Despite the cost reason, due to increasing the high capacity, the weight will increase at the same time, too much weight will influence the E-bike loading and influence the endurance mileage as well. So choose the suitable lithium battery pack according to your using application, instead of just choose the one with highest capacity.
