Your ebike’s battery isn’t working or you just want to replace it to improve bike performance. On that note, 48V battery would be the best option as a decent power house for your electric bike.

While 36v ebike batteries provide somewhere enough juice to the motor, a 48v battery is your best chance for maximum output. This is especially necessary to ensure if you’re building one with a conversion kit.

Now, if you’re thinking if it’s possible to get a high-quality and high-performance 48V battery at an affordable price, you’re in luck. We’ve seen both volgate levels, found 48 to be better, and listed the 10 best 48v batteries for electric bike that you can get today. 

We included all the high-performance 48V batteries for your e-bike build. The best part is- some of them come under $200. So, let’s check out the list.

Are E-Bike Batteries Universal And Interchangeable?

No, e-bike batteries are not universal and interchangeable with all ebike models, they differ from one brand or model to another. Electric bikes also need specific type of batteries depending on the type and power of BMS (Battery Management System). You want to consider the following criteria while getting your ebike battery:

  • Voltage
  • Ampere Capacity
  • Watt-Hour
  • Size
  • Weight
  • Control

It means you can’t mount a 48V battery to a 36V electric bike. Never make this mistake again by thinking that every electric bike’s battery is the same though they look alike, unless the BMS is well capable and rated for 48v.

Are E-Bike Batteries Universal And Interchangeable

If you want to change the battery of your electric bicycle, ensure the battery you are going to pick is compatible with your ebike. Otherwise, it will not work or bring hazardous damage to your e-bike by destroying the battery & motor.

Now, you may ask- why the batteries for electric bikes are not universal?

Simple, the specifications of every type of lithium-ion battery are different. And guess what, batteries with different specifications like voltage or current will generate different watt-hours.

Additionally, you should get a battery that comes with the same voltage and ampere-hours. Of course, the battery should match the total wattage of your e-bike. It’s because a 48V battery won’t produce the same amount of watts-hour as a 36V battery does.

Another thing you should take into account is- never go for a higher voltage battery than the voltage an electric bike requires. If you do so, it may overcharge the battery and it may stop functioning. Indeed, batteries for electric bikes are not universal.

Next, let us break down the second part of the question- why are electric bike’s batteries not interchangeable?

You can’t share batteries between electric bicycles because the watt-hours of the battery may be different from the allowable wattage of your electric bike.

In short, electric bike batteries are not universal and interchangeable. You should replace the damaged battery with a new one that will match the voltage, ampere-hour, watt-hour, size, and weight of the existing battery.

How Powerful Is Ebike 48 Volt Battery?

The Volt in a battery will determine how powerful a battery is. An electric bike battery with higher volts will supply more current. And the more current a battery will generate, the more power you will get from the battery. It’s a pretty simple calculation.

How Powerful Is Ebike 48 Volt Battery_

Compared to a 36V battery, a 48V battery will draw more current, typically around 10-40 amperes. In other words, you can gain higher speed and go fast with a 48V electric bike battery.

Apart from the power, there are other benefits you can enjoy if you go for the 48V battery. The 48V battery is a common type battery. So, you will get better packs and options when it comes to replacing the battery.

Criteria Should Look For When Buying A 48v Battery For Electric Bike

Every e-bike battery manufacturer offers an electric battery with similar features & accessories. So, it will be a bit challenging which battery you should pick from what brand. To make your buying decision easy, we recommend you consider the following criteria.

Buying A 48v Battery For Electric Bike

Battery Type (Lithium ion)

Electric bikes come with several types of batteries. They are lithium-ion, lithium polymer, lead-acid, and nickel-cadmium. Each of them has upsides and downsides

Lithium batteries are the most common type of battery you can find everywhere. The lifespan of this battery is longer, and the charge of this battery will last for a long period.

On the other hand, Lithium Polymer is the most powerful battery. The power it delivers exceeds every type of battery available on the market. It will be a great option for mountain riders.

Lead-acid is another electric bike battery well-known for its high availability. However, we don’t recommend this battery because it’s less powerful and has less lifecycle.

Finally, you can find another type of battery named nickel-cadmium. The rare part of this battery is- you need to charge it fully before using it and discharge it fully before storing it. Such a battery will not be the right fit for electric bikes.

Amp-hour Capacity

Considering the amp-hour capacity of the battery is indispensable. How many miles you can go will depend on the amp-hour capacity of your e-bike battery.

To know the capacity of the battery, you should do a little bit sum:

Multiply the voltage and amp-hour rating of the battery. For example, suppose the battery you are going to pick has 48 voltages and 15Ah. So, watt-hours output you will get is (48*15) 720Wh. In other words, such a battery will deliver 720 watts for an hour or less than that with full speed.

Now, if you have an electric bike with a 500W motor, you can run it for 1.44 hours by operating the motor at full speed.

Easy to Mount or Not

Next, check the size of the battery and calculate its measurement to understand whether you can mount it on your e-bike or not. Fortunately, every electric bike we enlisted comes with a mounting bracket to mount the battery with ease. So, you don’t need to worry about it.

Charging Cycle

How long a battery will support you depends on the charge cycles. The quality of the battery cells will also determine the durability of your e-bike battery. You can operate most of the batteries on our list after 1000 cycles. And the best part is- every battery will support you for 5 years as they pass the industry standard.

Battery Peripherals

Almost every electric battery we reviewed comes with a charger. It means you don’t need to buy a separate charger to charge the e-bike battery. Also, make sure the battery has a USB port. It will help you charge your smartphones in an emergency case.

Charge-up Time

It is also an important criterion you should consider. A battery with a quick charge-up time will let you enjoy the thrill of biking within a few hours. Most electric bicycle batteries we reviewed will take between 7-10 hours to fully charge the battery.

Safety Features

Safety comes first, right? You don’t want to get a battery that will blast out due to overcharging or overheating. Fortunately, every 48V e-bike battery features BMS. It will protect your battery from overcharging, overheating, short circuits, and others.

Plus, each battery comes with a safety lock feature. So, there is no risk of getting the battery stolen. Turns out, every battery comes with a waterproof casing to protect the battery against rain or mud.

Warranty

Of course, getting a battery for an electric bike requires a lot of investment. So, you should check whether the battery comes with a warranty or not. A battery with a warranty will help you get a free replacement.

Frequently Asked Questions
