best lithium battery for ebike

#1 AW Lithium Rechargeable Battery 

top-rated best ebike batteries

AW 36V 10AH / 36V 14AH / 48V 14AH Lithium Rechargeable Battery at a Glance

  • Battery Type: Lithium
  • Voltage: 36V or 48V
  • Amperage: 10AH or 14AH
  • Weight: 8.6lbs
  • Longevity / Life: 1000 charging cycles

This AW model is a great-looking lithium battery and uses regenerative breaking to extend the battery life. It’s known as a “water bottle” mount because it’s lockable mount bracket bolts to a bicycle frame using the same threaded offsets as water bottle cage. The battery cell portion is lockable and removable for security.

It is absolutely necessary to waterproof this battery if it is being used in rainy conditions. Aside from that, under regular conditions, this lithium battery performs well. It has an impressive range of around 50 miles when combined with a bit of pedaling and the acceleration is also impressive.

AW offers lithium rechargeable Ebike batteries (36V 14AH and 48V 14AH) that mount on a rear rack that is included with the battery. The battery clicks into place on the rack and is locked in with a key, and is easy to remove and take indoors with you to prevent theft and in case rain is expected.

This is a popular format for Ebike batteries but sacrifices some storage space usually available on the rear rack. In general, the most powerful lithium batteries designed for electric bike conversion kits are being delivered in this format because of the ample size to accomodate the larger cell.

#2 Flying Horse ModWheel

Flying Horse ModWheel at a Glance

  • Lithium ion
  • 36V
  • 11AH
  • 5lbs
  • Over 800 charging cycles

The Flying Horse ModWheel is an expertly made piece of kit that is both reliable and powerful.

It is compatible with 250, 500, 750 and 1000 watt conversion kits, depending on the version you choose, placing it between the AW and the Joyisi in terms of power.

With 11 amp hours, It can easily exceed 20 miles in a single charge, even when used consistently.

You can attach the Flying Horse ModWheel either to a pannier rack on the back of the bike or on the down tube. Mounting is secure, sliding onto a rear rack and clicking into place. Then, you can lock it using a simple key, to stop any forward-thinking thieves from sliding it off the back.

The most expensive product on this list, the Flying Horse ModWheel has top specs, such as high-quality Panasonic cells and excellent build quality.

Although it claims only 800 charging cycles compared to the 1000 from the AW and Joyisi models, you won’t be disappointed with this battery.

This e-bike battery is also available in a 48 volt 11.6 amp hour version.

#3 Joyisi

Joyisi 48V at a Glance

  • Lithium ion
  • 48V
  • 15AH
  • 1000 charging cycles

The Joyisi 48 volt is a fantastic battery, jam packed with impressive power and capacity.

With 15 amp hours to draw on from one charge, the Joyisi 48 volt battery has the longest range of the items on this list, somewhere between 30 to 40 miles, depending on weight, speed, terrain etc.

The 48 volts work with 1000 watt conversion kits, meaning it is also the most powerful product we selected. This is obvious when you need it most, giving you a strong boost up hills.

It is attached to the rear of the bike via an included rack. Like the Flying Horse, you can lock your battery into place using one of the two keys provided for security and safety.

There is a useful handle attached to the back which you can flick open when sliding the battery out of the holder.

This is probably the best performance battery included here, yet cheaper than the 48 volt Flying Horse version — an awesome choice to enhance your bike.

#4 Mighty Max Baoshi

Mighty Max Baoshi at a Glance

  • Sealed Lead Acid
  • 4 X 12V
  • 22AH
  • 13lbs

The Mighty Max Baoshi is a sealed lead acid battery which immediately puts it in a different category to the previous three.

There are four 12 volt batteries which you can add to, or take out of, a series, depending on what your conversion kit requires. This gives you the flexibility to adapt your battery to your voltage needs, but isn’t as neat and discreet as the lithium batteries above.

Where these really win is in the price department. A total of 48 volts for around $165 makes them far cheaper than the 48 volts for around $460 you get from Flying Horse.

They are reliable and well built too, with shock absorbers and a spill-proof casing. The performance is not bad either, although not as good as the lithium batteries.

SLA batteries are slowly going out of fashion, but as long as the lithium batteries stay in their own league in terms of cost, batteries like the Mighty Max Baoshi will hold their place in the market for people experimenting with making electric bikes.

#5 Universal Power Group

Universal Power Group at a Glance

  • Sealed Lead Acid
  • 2 X 12V
  • 12AH
  • 16lbs

Universal Power Group offer two 12 volt batteries that can be run in series or alone to match your conversion kit’s requirements.

At just over $50 they are a steal and good value for money for e-bike experiments. The downside to this is that they don’t come with any mounting mechanism, nor a bag to attach them to the frame. The company claims them to be spill proof, so I would recommend making these (as well as all other) batteries waterproof before you head out for a spin.

In terms of performance, they simply can’t be compared to the lithium batteries, the weight worsening the already poor range.

I would recommend the Universal Power Group batteries to people who are building their own e-bike and can’t bear the thought of blasting up to $400 on a lithium battery.

They are not the most powerful, nor the most practical for e-bikes, but for a cheap battery that does the job, the Universal Power Group has got you covered.

Where to Find the Best Deals on Batteries

Over the past four years, our team at has been looking for the best deals available online. In that time, we’ve seen more than 30 great deals on batteries. In the chart below, you’ll see that many of those deals came from Amazon, Best Buy, Meh, The Home Depot and Walmart.

Battery Deals Posted by Since 2016 from Amazon, Best Buy, Meh, Lowe's The Home Depot and more.

As you can see, we’ve posted most of our deals on batteries from Amazon. The best deal we’ve seen on AmazonBasics AA batteries was a 100-count pack for $14. That’s only 14 cents per battery!

We’ve also posted several deals on batteries from Best Buy. In the past, Deals of the Day have included 48-packs of AA and AAA Insignia batteries for as low as $6. If you can catch this deal, you’ll be paying just 13 cents per battery. That’s the lowest price we’ve seen!Advertisement

Daily deal sites like Meh also offer great deals on batteries, but in my experience, they sell out fast. We’ve seen some great deals on bulk batteries from these sites in the past including 192-count packs for $30 at Meh. At 16 cents per battery, you’re still getting a great deal.

In the past, The Home Depot has matched Best Buy’s all-time-low pricing with a deal on a 60-pack of its store-brand HDX AA batteries for $8. Meanwhile, Walmart has been a close runner-up with past deals on 50-count packs of discount batteries for $6.97. That means you’d be paying only 14 cents per battery.

The Top 5 Best Places to Buy Cheap Batteries

While finding a great deal on batteries is one of the best ways to get the lowest price per battery, you may not be able to wait for the sale. If you’re looking for the lowest daily prices on batteries, check out Walmart, Sam’s Club, Amazon, Costco and Best Buy. 

I visited each retailer’s website to find the best available deal on AA and AAA batteries at the time of this writing. I’ve provided details about each store later in this article, but just below you’ll see the per-battery cost of each deal: 

Sam’s Club$0.31$0.29
Best Buy$0.42$0.42

Sam’s Club, Amazon, Costco and Best Buy offer competitive prices on store-brand batteries while Walmart offers great deals on generic brands. As a comparison, I found CVS-brand AA batteries for 69 cents each and AAA batteries for 78 cents each. At the same store, name-brand Duracell batteries ranged from $1.35 to $1.90 each!

“If you buy batteries at a drugstore, convenience store, supermarket or anything like that, what you’re paying per battery is mind-blowing,” says Clark. “So, it’s not just that you buy the store brand, it’s where you buy also that really matters.” 

For the best overall prices, consider shopping at one of these top five places to buy cheap batteries:

1. Walmart

ACDelco AAA batteries at Walmart

While Walmart doesn’t offer private-label batteries, you can still find some of the best prices on off-brand batteries at At the time of this writing, I found a 60-count pack of AA Rayovac batteries for $17.97 and a 100-count pack of AAA ACDelco batteries for $24.99. These were the best deals I found on AA and AAA batteries during my research.

Note that while you may find low prices online at Walmart, you can expect additional shipping fees if in-store pickup isn’t available

While Walmart’s prices are great on off-brand batteries, name brands come with a bigger price tag. For example, a 36-pack of Duracell AA batteries was available for $30.05 at the time of writing, which means they cost 83 cents each.Advertisement

2. Sam’s Club

Member's Mark AA batteries from Sam's Club

If you’re a Sam’s Club member, this is a great place to shop for cheap batteries. 

When I compared prices, I found Member’s Mark 48-count packs of batteries for $14.98 and AAA batteries for $13.98. At the time, there was a $2-off Instant Savings discount on the batteries. That made these two available deals the second-best I’d seen.

“Sam’s Club’s a great option,” Clark says on shopping for cheap batteries. “It has all five major batteries in the company’s private label, and you just save money!” 

Sam’s Club’s store brand, Member’s Mark, is available in AA, AAA, C, D and 9-volt sizes.

3. Amazon

AmazonBasics AA batteries from Amazon

For Amazon Prime members, AmazonBasics batteries are going to be hard to beat. 

“I’m a big fan of AmazonBasics,” says Clark. “They’re not as cheap in the AA and AAA batteries, but the AmazonBasics 9-Volt, the Cs and the Ds are a real deal.

While the AmazonBasics didn’t have the lowest prices I saw, they were still very competitive at only one or two cents more per battery than Sam’s Club. In the past, our team at ClarkDeals has found AmazonBasics AA batteries even cheaper at $14 for 100. That drops the normal 31 cents per battery price to only 14 cents!

Of course, Prime members are eligible for free two-day shipping for even more savings.Advertisement

4. Costco

Kirkland Signature AA batteries available at Costco

In the past, Costco’s Kirkland Signature batteries have been the best available deal. While you can now find other off-brand batteries cheaper elsewhere, Kirkland Signature is still a great choice. In fact, Consumer Reports included the Kirkland brand in its “Top 5” recommended batteries roundup. These batteries are also the only brand considered a “Best Buy” on the same list.

Even though Kirkland Signature no longer has the lowest per-battery cost, you can rest assured that you’re getting quality batteries for under half the price.

“At Costco, it’s Duracell that makes Kirkland Signatures,” says Clark. “They’re not similar batteries; they’re identical.”

CVS offers Duracell batteries at $1.35 to $1.90 each. With Kirkland Signature, you’re getting the exact same thing for only 35 cents: That’s $1 less per battery!

5. Best Buy

AA Insignia batteries available from Best Buy

As you can see above, Best Buy’s Insignia batteries aren’t going to have the lowest daily price you can find. However, if you can grab Insignia batteries on a day they’re on sale, the price will be impossible to beat.

In the past, ClarkDeals has seen daily deals including 48-count packs of AA and AAA batteries for as low as $6. That’s only 13 cents per battery! Again, that’s the lowest price we’ve seen. I always try to grab this deal when it comes up, and the batteries last a long time.

Bookmark this page to keep up with the best daily deals at Best Buy, and when you see the batteries on sale, be sure to get them! Choose free in-store pickup nearby to avoid any additional shipping costs. In my experience, they’re typically ready for pick up in less than an hour.

Final Thoughts

Overall, you’ll likely find low prices on store-brand and off-brand batteries at Walmart, Sam’s Club, Amazon, Costco and Best Buy. Advertisement

If you see a good price on a battery brand that you’re not familiar with, especially at a store like Walmart, be sure to read customer reviews and check out Consumer Reports’ battery reviews to learn more about the brand’s performance.

“There are some sellers who sell these batteries that aren’t very good,” cautions Clark. “So if you buy completely off-brand batteries, you could end up with one that’s very unreliable and doesn’t have a long life.”

Sam’s Club members, Amazon Prime members and Costco members all have access to great prices on quality store-brand batteries like Member’s Mark, AmazonBasics and Kirkland Signature batteries respectively. Free shipping with these options also leads to additional savings. 

Finally, hold out for the sale on Insignia batteries at Best Buy if possible. With this deal, you have the chance to get the lowest per-battery price that our team has seen in the past!

No matter where you decide to shop, be sure to use a tool like Google Shopping to make sure you’re getting the best available deal before purchasing.
