EBike Battery Features
Being a key component, you need to know which battery to choose for your electric bicycle.
Before you make your purchase, you need to look out for the following critical features:
- Voltage output: The nominal voltage of a battery.
- Capacity (Ah): The maximum amount of energy that the battery can accumulate, typically expressed in Ah.
- Life cycle: The number of charge/discharge cycles that a battery can do.
- Charging time: Determines the charging time. The more the battery is discharged, the longer it will take to recharge it. Batteries usually take a few hours to recharge.
- Self-discharge: All batteries, especially rechargeable ones, are subject to self-discharge after a specific time, regardless of whether the battery is used or not.
- Dimensions: This refers to the size of the battery that best fits the physical dimensions and terminal points of your electric bike.
- Ease of remove and reinstall.
- Design: An ebike battery should look nice.
Remember that the warranty of your ebike may be void if you do not replace the battery with the one indicated by the manufacturer.
So, the first thing to do is to contact the seller of your e-bike to ask for the battery replacement.
In any case, when you replace the battery, make sure that its specifications are suitable for your e-bike motor.
Electric Bike Battery Specifications: Choosing The Right Voltage and Amperage
For a better understanding of how batteries work, we shall briefly discuss the following units of measurement:
Volt
Volt defines as the unit for electromotive force, electric potential, and electric potential difference.
For the most part, batteries for electric bikes usually are in 24V, 36V, and 48V.
It is always advisable to use the recommended voltage.
This unit means that you have to choose the voltage corresponding to the motor of your e-bike.
It is good to note that the typical voltage for most ebikes is 36V.
Although few have a voltage at 24V while others have a voltage at 48V
Amp
This abbreviation is the shortened form for Ampere.
It is defined as the base unit of electrical current when it comes to the International system of units.
This unit of measurement defines the capacity of the battery.
The higher the capacity, the greater the range of your electric bicycle.
Choosing a battery with high capacity does not damage the motor so that you can opt for capacity based on price, size, and weight of the battery.
Watt
This is defined as the unit of measurement for power, which is calculated by multiplying VxA = Watt.
Ah (Ampere-hour)
An ampere-hour is a unit of electric charge, it has dimensions of electric current multiplied by time, which is equal to the charge (amount of electrons) transferred by a steady current of one ampere flowing for one hour.
The Ah is useful for expressing autonomy.
More hours of Amp correspond to a greater range of the electric bike.
Wh (Watt-hour)
Also known as the kilowatt-hour, this unit of measurement calculates the total energy of a battery (VxAh).
This data is also useful for expressing autonomy.
About The Speed Controller
The electronic speed controller is the device that limits the power and maximum speed of the bike.
Typically, a standard electric bike must respect the maximum limits of power and speed to be classified as a bicycle.
However, if you are building an electric bike, you will have to buy a controller that has characteristics that meet the limits that classify it as a bicycle, according to the regulations of your country.
You should, therefore, avoid building an electric bicycle that is too fast if you have a controller that allows it.
What Technology Type Of Battery Should I Get For My Ebike?
The quick answer is: The Lithium-ion (Li-ion) battery.However, it is good to know some of the other ebike battery types available on the market.List of the most common battery technology types:
- Lead-acid (SLA)The lead-acid is the oldest type of rechargeable battery.These batteries can supply high currents, and the applications are varied, such as automobile starting, electric scooters, electric wheelchairs, golf carts, and much more.
- Nickel-cadmium (NiCd or NiCad)The nickel-cadmium battery is a type of rechargeable battery using metallic cadmium and nickel oxide hydroxide.
- Nickel-metal-hydride (NiMH)A nickel-metal hydride battery is a type of rechargeable battery.The chemical reaction when it is on a positive node is said to be similar to that of the nickel-cadmium cell (NiCd).However, a hydrogen-absorbing alloy is used by the negative electrodes instead of cadmium.A NiMH battery is said to possess two to three times the capacity of an equivalent size NiCd.
- Lithium-ion (Li-ion)A lithium-ion battery or Li-ion battery is a type of rechargeable battery where lithium ions go to the positive electrode from the negative electrode during discharge and also come back during charging.These batteries make use of an intercalated lithium compound compared to the non-rechargeable lithium battery that uses metallic lithium.They have an outstanding record of low self-discharge.They are also growing in popularity for battery electric vehicle, military and aerospace applications.
- Lithium-ion Polymer (Li-pol)A lithium polymer battery, or more correctly lithium-ion polymer battery usually abbreviated as LIP, LiPo, Li-poly, lithium-poly, and others, is said to be a battery of lithium-ion technology that uses a polymer electrolyte instead of a liquid electrolyte.
- Lithium Cobalt (LCO)This type of battery consists of a cobalt oxide cathode with a layered structure.Graphite (carbon) is said to be the anode for the Lithium Cobalt (LCO) battery.
- Lithium Manganese (LiMg204)A Lithium-ion manganese oxide battery is a lithium-ion cell that makes use of manganese dioxide as the primary cathode material.They are said to be a promising technology as they have manganese-oxide components, which are great for a reliable battery to function effectively.
Why Are Lithium-ion Batteries Better?
On this note, it is essential to know that the best type of battery needed for an ebike is the Lithium-ion (Li-ion).Mostly because it has a high technology that makes it a low self-discharge.Many electric bike owners do not make use of their bikes at all times, and that is why it is good to purchase a battery that you will be sure to last in terms of battery strength even when you are not making use of it.Lithium-ion (Li-ion) is also a prescribed type of battery for electric bikes since it has an active protection technology that makes it durable in all kinds of weather conditions.This battery can withstand both hot and cold weather with little or no sort of damage encountered.

1. Remove for cleaning whenever necessary.
It is very important to clean the lithium battery at least once a month or even more often if necessary.
This custom helps to reduce dust and other dangerous particles that stick to the surfaces, which might tend to damage the battery.
2. Always charge up the battery before use.
The battery has to be fully charged before you consider taking it out for a ride.
3. Always ensure that your battery is tightly clipped to the ebike.
Surely, some rides prove to be bumpy and rough. There is every possibility that the battery may fall if not tightly held to the bike!
4. When it’s time to store the bike, charge the battery to 80%, clean, and then kept in a moisture-free room.
For best performance insurance, it is recommended to charge the battery to 80% when not in use, recharging once every 2/3 months.
5. Keep your ebike tires inflated.
When the tire pressure is in a perfect and required amount, it influences the battery life as the battery does not get to stress itself, trying to produce enough energy to propel the bike.
6. Always use a battery cover.
This helps to prolong the life of the battery and also make it perform better in all weather conditions.
