Buyer’s Guide: What Are The Features Necessary In Your Electric Bike Battery?

Picture this: you step inside the market, ready to buy the best battery for your e-bike. However, when you look at the plethora of options, you’ll either feel intimidated, or you’ll be extremely confused. But worry not! To help you make the right e-bike battery decision, we’ve listed some things you should keep in mind when purchasing. Ready to learn? Let’s get started then!

Battery Capacity And Voltage

When buying a battery for your e-bike, it’s essential you check the voltage of the battery. What is voltage? You ask. Well, voltage is the flow of energy, which means voltage refers to the pressure at which electricity moves through your bike.

In short, voltage determines the speed at which your bike moves. Therefore, the higher the voltage, the more power your bike will have, and the faster it will go. And who doesn’t want that?

Capacity

The capacity of a battery translates to how long your battery can survive before dying. Measured in watt/amp-hour, one downside of more capacity is that it means your battery will be heavier.

The most common capacity is 10 or 20 Ah. This works best if you ride your e-bike on flat surfaces and go for short rides. However, if you like to travel on rougher terrains and go longer distances, then you’ll have to consider something heavier.

Battery Range

A battery’s range depends upon several factors. The bike itself, the size of your battery, the terrain, tire pressure, air resistance, support level, and your weight. Depending on whether you want to use the battery for going long distances or not, you can determine which battery works best for you.

Stability Of The Battery

What good is your battery if it is neither reliable nor does it last long. Just imagine the amount of money you’ll save if you don’t have to buy a new e-bike battery every six months.

With ever-evolving technology, this is usually not a problem. As long as you ensure your battery isn’t overheating, durability and reliability won’t be a problem.

Portability 

Portability should be your number one priority. If your battery is too heavy, there’s a high chance your e-bike won’t work properly. And unless you want to travel long distances and go over rough areas, you won’t need them.

Lead-acid batteries are usually heavier and perfect for going long distances. Lithium-ion batteries, on the other hand, are comparatively lightweight and easy to carry around.

Frequently Asked Questions (FAQs): Electric Bike Batteries

Q: What are electric bike batteries made up of?

A: Electric bike batteries can be made up of several materials. The most common battery types include the following

• Lead-acid
• Nickel-cadmium
• Nickel-metal-hydride
• Lithium-ion
• Lithium polymer

Lead-acid batteries are usually constructed in China. However, lithium-ion and lithium-polymer ones are commonly fabricated in the UK. Due to their weight and quality issues, lead-acid batteries are rarely found in places other than China.

Q: How long does the battery of an electric bike last?

A: The life of your e-bike battery depends upon several factors. The type of battery you purchase, the speed you go at, whether you travel uphill more or less, and the way you take care of it.

Plus, battery life is calculated by the number of charge cycles they can undergo. As long as you take care of your battery, it can last up to 3 to 5 years.

Q: How do I take care of my battery?

A: Some easy ways to add to the life of your battery is by taking care of it. Here are some ways you can do that:

• Be sure to use the charger and adapter that comes with your e-bike battery. This avoids any short circuits from taking place.
• Don’t drain your battery completely. However, try charging it until 100%.
• Always take your battery off after it’s completely charged.
• Store your battery in a cool and dry place.
• Remember, your battery doesn’t appreciate water. Therefore, when you’re cleaning your bike, be sure to take it off.
• Even if your battery is waterproof, don’t immerse it in water. Use a damp cloth to clean it.
• Leaving your battery unused for more than three months will affect its longevity negatively. So even if you don’t use it, charge it partially every so often.

A: Yes, even if your battery runs out of juice, you can ride it. The pedal-assisted e-bike allows you to ride your bike like a conventional one.

Q: Can I use my e-bike battery if it’s cold or raining?

A: Yes. If it’s cold or raining, you can still ride your e-bike with the battery attached. You might need extra gear in the winter, but other than that, there’s nothing you need to worry about. However, we advise you to leave your charger at home.
