We live in a changing world. The price of petrol is rising. Due to the rising price of fuel oil, people are turning away from petroleum. People have become more interested in electric vehicles. One of the most significant parts of an electric bike is the Battery (e-bike). The batteries will have an impact on the e-speed bike’s duration. Many prefer to retrofit or DIY their e-bike to increase horsepower or design a distinctive appearance. So, which Battery should we choose for an e-bike?
5 Types of Electric Bike Batteries
Lead-acid Electric Bike Batteries (SLA)
Lead-acid batteries are inexpensive and simple to recycle. Lead is one of the most effectively recycled elements worldwide, and recycling now produces more lead than mining. They do, however, require maintenance and do not live very long. If you’re serious about riding your bike to work, this isn’t viable.
This Battery has these qualities:
- Raw resources are inexpensive.
- They are double the weight of NiMh batteries and three times that of lithium batteries.
- They have significantly less useable capacity than NiMh or lithium batteries. Only half the life of nickel or lithium batteries.
However, lead-acid batteries have gradually phased out in favor of lithium iron phosphate (LiFePO4) batteries. At the same time that battery costs have decreased, so have the lifespan and average cost of lithium iron phosphate batteries.
Nickel-cadmium (NiCd) Electric Bike Batteries
Nickel-cadmium batteries offer a larger capacity than lead-acid batteries, and capacity is an important consideration when purchasing the best electric bikes. However, nickel-cadmium is expensive, and cadmium is a hazardous contaminant that is difficult to recycle.
On the other hand, Nickel-cadmium has a longer lifespan than lead-acid batteries. However, because they are so difficult to recycle or dispose of responsibly, NiCd batteries are rapidly becoming obsolete. Regardless of price, these are not acceptable options for battery type.
Nickel-metal Hydride (NiMH) Electric Bike Batteries
NiMH batteries are slightly more efficient than NiCd batteries. However, they also cost more. Most people believe NiMh has a minimal advantage over NiCd in terms of range. On the other side, they will endure longer and are easier to dispose of properly. Following are the benefits of a Nickel-metal Hydride (NiMH) electric bike battery.
- Extremely Large Capacity.
- Self Discharge is low.
- Safety and dependability.
- Environmentally friendly
- No memory effect.
- Uniform temperature performance.
- Quick charge capability.
- Increased Cycle Life.
Lithium-ion (Li-ion) Electric Bike Batteries
The new Battery promises to be no better in terms of range, weight, or price than Li-ion batteries. However, it can be shaped into many shapes, accommodate additional gadgets, and has extra lithium-ion batteries ( Li-Po, LFP) that are great for achieving fast rate charge/discharge. In addition, they are also ideal for powering high-power applications such as electric bikes, go-karts, drills, and other industrial applications. Other than bike batteries, electric bike motors are also an important part of the vehicle.
Lithium-ion Polymer (LiPo) Electric Bike Batteries
Lithium-ion Polymer (LiPo) has become the standard Battery for electric bikes (i.e., e-motorcycles), accounting for more than 90% of the market. The LiPo battery is a rechargeable battery that is inexpensive and relatively easy to discharge at higher C-rates, allowing it to supply more power in a shorter amount of time, as well as fast charging and high voltage. In terms of the advantages of high-voltage batteries, the discharge power consumption of the Battery must be expressed as P = V * I. . Increasing the maximum cut-off voltage can boost the overall discharge energy of the cell in mA*h.

Keep in mind that the rider’s weight, ambient weather conditions, and quantity of pedaling all have an impact on range. Assume that one mile takes roughly 25Wh of energy on average. A 14Ah, 36V Battery should provide around 25 miles per charge. Watt-hours are computed by multiplying the battery capacity (in Amp-hours) by the voltage (in Volts).
A word of caution: the range provided by e-bike manufacturers should regard with skepticism. This figure has derived from testing performed in precisely suited laboratory conditions. Do you charge your electronics in a 28° C incubation chamber using a lab-grade charger that applies the perfect current while charging? No, neither do I. As a result, we should presume that the manufacturer-specified range is a supplier if the Battery is charged and discharged under ideal conditions rather than real-world ones.
