Best 48V ebike Battery (Recommendations and Guide)

For electric bikes, the size and power of the battery matter a lot. And, I know that lots of you are not happy with the runtime of your existing battery pack. But the sky is the limit when it comes to voltage and output current.

With higher power and increased running distance, the cost becomes almost unbearable. After thorough research, I have found a sweet spot. A 48V Ebike battery sits somewhere in the middle that increases the mileage without costing you thousands of dollars.

Again, the problem occurs when buying the right and best electric bike 48v battery. Let me save time and trouble by reviewing 7 top-rated and trusted models in the market. Let’s begin.

Recommended Top 7 Product List:

  1. Unit Pack Power Battery – Best Overall
  2. Joyisi Battery – Runner-up
  3. VISET Battery Pack – Best Budget
  4. QZF Lithium-ion Battery with Charger – Most Powerful
  5. SZ Batteries Grade A Cell – Waterproof and Powerful

How to Choose the Best 48v Ebike Battery?

Almost all of the manufacturers of 48V battery for Ebikes offer a similar type of features and accessories. However, they vary a lot in terms of performance and output power. So, read my buying guide thoroughly to understand how to buy matching all your requirements.

Amp-hour Capacity

The first factor to understand always keep in mind is the amp-hour capacity of your chosen battery model. If you multiply the battery voltages (48V in this case) with amp-hour rating (20Ah for example), you will get the power output for an hour and estimated runtime. Let me explain.

48 times 20 equals 960 watt-hours or 0.96 kWh. Such a battery pack can deliver 960 watts for an hour or slightly less than an hour with a full load on its output.

For a 500W motor running at a full speed, you can expect it to operate for 1.92 hours or less. With reduced load, you can get an increased runtime.

Now, you have to measure the power consumption of your Ebike at a certain speed. Then, divide the amp-hour capacity (in watts) by that load (in watts).

The result will tell you the runtime and multiplying the result with speed will show you how many miles per charge one can go. This way, you would know whether the capacity is enough for your requirements and support the full range of the motor.

Design and Mount

After that, see the design, and measurement to understand whether it would be an easy mount for your Ebike or not. However, most electric bike batteries come with mounting accessories. So, you probably don’t have to worry about that much.

Also, check whether it is waterproof, and most of the models are. Otherwise, you will have to use a separate casing for the battery pack to protect it from water and snow.

Charge Cycles

Besides the casing, durability also depends on the quality of the cells. A standard good-quality battery cell should still be operating after 1000 cycles of charging and discharging. And, I can say that ordering one of the lithium batteries from my list won’t fail you as they all pass this standard.

Charging

Finally, go through the listing and see whether the seller is offering a charger. It would be convenient because you won’t have to look for a compatible charger and spend some more money.

Moreover, it would come in handy if the pack has a hard casing with a USB charging dock. With the dock, one can charge important electronic devices like a smartphone in emergencies.

Frequently Asked Questions (FAQs)

How long to charge a 48v Ebike lithium battery?

Almost all Ebike batteries are lithium-ion and it can take from 3.5 hours to 6 hours to fully charge a 48V unit. The exact time depends on several factors including the quality of the connection, control circuit, cells, and charger.

How long will a 48v 10ah E-bike battery last?

If you multiply those two values, you will get the capacity at full load. 48 times 10 equals 480; so, the battery can deliver 480 watts per hour or 0.48-kilowatt hour. And, your bike won’t be using the full output capacity of the battery which makes the runtime longer.

How many cells are in a 48v Ebike battery kit?

The number of cells varies based on the quality of the cells. In a 48V 12Ah battery pack, you can expect around 52 good-quality cells or around 130 cheap-quality cells.

How long will the 48v 20ah Ebike battery last?

I have already answered a similar type of question above. The answer would be 980 watts per hour (0.98 kWh). So, you can run a motor consuming 980 watts for an hour. For less consumption, you will get more runtime.

How many amps is a 48-volt battery?

There are no definitive answers to that because there are lots of different battery packs offering various power outputs. From my list above, you can see that they range estimates from 12.5 to 50 amps.

How long will a 48v 17Ah Ebike battery last?

Such a battery can run a motor consuming 816 watts for about an hour or less.

Can you charge a 48v battery with a 12V charger?

In order to push current into the battery pack, the charger must have a higher voltage than the pack. So, it is not in any way possible to charge a 48V battery with a 12V charger.

Final Words

So, which one do you consider the best 48V Ebike battery? With the highest ratings and popularity, I would bet on the Unit Pack Power. It has a balanced set of features and a reasonable price.

On the other hand, the runner-up model is also admirable for its rear-rack mounting design and lots of user-friendly design. However, those who want an even more powerful pack with convenient mounting features must get the 6th model from Co-well.

48V batteries are a good replacement for the stock ones. It can last longer and provide more runtime. Now, it is time to make up your mind, and order a pack from the list. Let me know which one you have picked for your Ebike.
