Lightweight:
Electric bicycle batteries are usually designed to be as light as possible so that they can be easily installed on the bicycle without adding too much burden. Common materials include lithium ion (Li-ion), lithium polymer (Li-poly), lithium iron phosphate (LiFePO4), etc.
High energy density:
In order to provide sufficient driving range, electric bicycle batteries need to have high energy density. This means storing more energy in a smaller volume, thereby extending the riding distance after a single charge.
Fast charging:
Excellent electric bicycle batteries support fast charging technology, shorten charging time, and improve convenience of use. Generally speaking, the shorter the time from empty to full charge, the better.
Long life:
The battery has a long cycle life and can undergo multiple charge and discharge without significant capacity decay. This usually depends on the material and technical level of the battery.
Safety:
Electric bicycle batteries must undergo rigorous safety tests to ensure that dangerous situations such as overheating, short circuit or explosion will not occur under various conditions of use. The built-in protection circuit can monitor the battery status and prevent overcharging, over-discharging and other phenomena.
Environmental protection:
Electric bicycle batteries are made of environmentally friendly materials, and waste batteries can be recycled and reused to reduce environmental pollution.
Lithium-ion battery (Li-ion):
The most common type of electric bicycle battery on the market, with the advantages of light weight, high energy density and long cycle life. Commonly used lithium-ion batteries include ternary lithium (NMC), lithium manganese oxide (LMO), etc.
Lead-acid battery (Lead-Acid):
The cost is low and the technology is mature, but the weight is heavy and the energy density is relatively low. Usually used in low-end electric bicycles.
Lithium iron phosphate battery (LiFePO4):
It has good safety and long cycle life, and is suitable for application scenarios that require frequent charging and discharging. But the energy density is slightly lower than other lithium-ion batteries.
