How To Know Which E-bike Battery Is Proper For You

E-bikes as an idea stretch again nicely over a century, however it is just lately that they’ve turn into environment friendly, sensible and dependable sufficient to hit the mass market.

ebike battery guide image

Electric bicycles handle to beat every little thing that’s fallacious with trendy transport: visitors, air pollution and a sedentary way of life, so it’s no marvel the business is on the rise.

China has led the cost and can proceed to make up an enormous part of the market, however with roughly 40 million models anticipated to be bought worldwide in 2023, the wave is predicted to engulf Western Europe earlier than heading to North America.

Nevertheless, with ever-altering developments in all departments, the internal workings of electrical bikes stay fairly a thriller. Nowhere is that this extra true than within the totally different efficiency, stability and longevity of e-bike batteries.

Right here at Outdoors Pursuits, we have now made up a various record of the highest e-bike batteries available on the market in the meanwhile, so you’ll be able to discover what sort of merchandise are on the market.

Additional down the web page, you can see a complete deconstruction of the batteries, analyzing the distinction between batteries and tips on how to get most efficiency out of them.

Kinds of Batteries

Selecting a special sort of battery is the most important change you can see from one product to a different.

It isn’t only a easy query of selecting between a sealed lead-acid, nickel based mostly battery or lithium battery, there are various variations of every sort of battery and myriad outcomes that every one has.

Sealed lead-acid

These batteries have been round for over 100 years, so the know-how has been refined over time.

On the plus aspect, they’re the most cost effective on the market and might be simply recycled. That is nice for people who find themselves constructing their very own bikes on a restricted price range.

Nevertheless, with the introduction of the next two battery varieties, they’ve actually been outdone when it comes to efficiency.

They’re very heavy, don’t final very lengthy, have much less capability and are extra weak to altering climate circumstances than their rivals.

Until worth is an absolute prime precedence for you, otherwise you simply need to experiment constructing your personal e-bike, my recommendation can be to avoid lead-acid batteries.

Nickel Batteries

There are not any nickel-based mostly batteries on this listing as a consequence of their temporary time because the chopping-edge know-how, however to go away them out of a run down of e-bike batteries can be a disservice.

Nickel Cadmium

A step up when it comes to power density, nickel-cadmium can retailer extra power per pound than lead-acid batteries, which is likely one of the most essential elements when selecting your e-bike battery.

Sadly, they’re fairly poor when it comes to recyclability and are fairly a harmful pollutant.

Nickel-metallic Hydride

Nickel-metallic hydride batteries beat cadmium variations relating to recyclability, and they’re additionally extra environment friendly, however they don’t symbolize an enormous enchancment on their Cadmium cousins.

The way forward for nickel-based mostly batteries seemed vibrant for some time, however since lithium batteries got here on the scene, they’ve been considerably forged into the shadows.

Lithium-ion batteries

Lithium-ion batteries have been absolute recreation changers within the e-bike and lots of different industries, and I don’t assume will probably be lengthy till they compete their rivals out of existence.

They enhance additional on the nickel batteries when it comes to power density, producing a very spectacular quantity of energy in change for little or no weight. Versus older batteries, additionally they deal with excessive and low temperatures higher.

One draw back is that lithium batteries are nonetheless not 100% secure (keep in mind Samsung’s PR catastrophe?) and much costlier than SLA batteries, however they’re quickly enhancing.

Their excessive power density, sluggish price of discharge when not in use, low upkeep and huge vary of variations have induced an excellent leap ahead in battery know-how.

Fast tip: When searching by way of e-bike batteries, you’ll typically discover that they’re merely known as “lithium batteries”. Most producers don’t specify which variation of lithium batteries they use, however the majority, just like the Flying Horse for example, are Lithium Cobalt.

Lithium-ion Polymer Batteries

In terms of value, weight and vary these are just about similar to common lithium-ion batteries.

What units these aside is the power to mould them into many various shapes. What’s extra, they don’t include any liquid, making them immune to overheating.

Lithium Phosphate, Lithium Cobalt and Lithium Manganese

Whereas polymer batteries are related due to the best way they’re made, they don’t check with the chemical make up inside. Under, you’ll find three fashionable kinds of lithium batteries in use right now.

Lithium phosphate’s benefit is in extracting a bigger quantity of amps out of them, and subsequently extra energy and acceleration. The draw back of that is that they take up numerous weight.

Lithium cobalt batteries are being produced in huge numbers today, and they’re utilized in every little thing from Tesla automobiles to laptops. They produce round double the watt hours as a lithium phosphate for a similar measurement and weight.

These days, virtually all e-bike battery producers that use lithium batteries go for lithium cobalt batteries over lithium phosphate, choosing a light-weight, lengthy-vary bike over a heavier, however quick-accelerating one.

Lithium manganese batteries are one other results of the evolution of lithium batteries. Used within the Nissan Leaf and a few elite electrical bikes, it’s stated to be one of the best base for an e-bike battery presently in existence, with reportedly larger energy and higher vary than all different lithium batteries.

Battery Applied sciences for the Future

One factor is for sure, advances in battery know-how present no indicators of stopping, so you possibly can make certain that new variations of lithium batteries will probably be popping up quickly sufficient.

Take a look at this listing of batteries for the longer term and let your creativeness run wild.

Technical Elements


Batteries are nothing and not using a conversion package, so before you purchase, ensure you are conscious of what sort of motor you’ve gotten and the facility it requires.

Voltage — Velocity

You may keep in mind what voltage is from highschool, however right here’s a refresher simply in case.

Voltage refers back to the strain that electrical energy is moved. You’ll discover that the SLA batteries on this record have 12 volts per pack, whereas lithium batteries can generally deal with 36 and 48 volts every.

The voltage listed for every battery refers to the usual quantity that runs out of the battery, not considering heavy bursts, which would require a better voltage.

A excessive voltage principally interprets into a quick bike, and the voltage displayed represents the voltage for normal use. This fluctuates for bursts of velocity.

Amp Hours (Ah) — Capability

In easy phrases, amp hours confer with cost capability — how lengthy your battery can provide a gentle present of 1 single amp earlier than it expires.


1Ah = 1 amp for 1 hour

1Ah = 2 amps for 30 minutes

1Ah = zero.5 amps for two hours


20Ah = 20 amps for 1 hour

20Ah = 40 amps for 30 minutes

20Ah = 10 amps for two hours

As a basic rule, the extra amp hours your bike battery has, the higher. No one has ever complained about having an excessive amount of battery provide.

In fact, having extra amp hours means a costlier battery.

Watt Hours

Watts and watt hours come into play when the electrical energy is transformed into power within the motor, so I’ll maintain this brief.

Watts are decided by multiplying voltage by amperage, so 36 volts and 10 amps will create 360 watts.

Like amp hours, watt hours combines the time a motor can maintain a specific amount of watts, e.g. 360 watts for two hours would imply 720 watt hours.

That’s helpful to know, however with batteries, we’re solely actually involved with voltage and amp hours.


To get a very good energy-to-weight ratio when selecting an e-bike battery, you want a great energy density. For instance, a 37 volt, 12 amp hour SLA battery from the 1990s might weigh round 36 kilos, whereas a 37 volt, 26 amp hour lithium battery these days can weigh simply 10 kilos. Over twice the amp hours at lower than a 3rd of the load.

SLA know-how has improved over 20 years, however lithium batteries are nonetheless in one other league in terms of power density. Selecting a battery with an excellent power density, such because the Flying Horse, means you get a number of energy for little weight.


Changing a battery is dear enterprise, so a extra secure battery can prevent a lot of cash in the long term.

SLA batteries are nonetheless a lot better than lithium when it comes to stability and reliability, however so long as you’re cautious with overheating, it might be uncommon to have issues with lithium batteries this present day.

Cost Cycles

Cost cycles confer with the quantity of occasions you’ll be able to cost your battery from flat to full in a single battery’s lifetime.

Batteries solely have a restrict quantity of cost cycles, round 1000 for many of those merchandise, earlier than they ultimately cease working. This implies you will get round three years of full costs day-after-day earlier than it dies.

Maximizing Vary

The most necessary end result you need from an electrical bike battery, and an e-bike usually, is sweet vary. Vary is just the space you’ll be able to journey on a single cost, and may be affected by the next elements:

Motor Effectivity

The matter of motor effectivity is just too difficult to cowl absolutely right here, however an excellent motor will convert a most quantity of electrical energy into ahead energy.

Battery Capability

Fairly a straight ahead part, the extra battery capability you might have, they additional you possibly can go on one cost. Simply keep in mind to cost it!

Tire strain

Identical to a automotive, if in case you have a low tire strain, that can be mirrored in how lengthy your battery lasts. Making your battery work to compensate for sub-optimum tire strain is a positive-hearth approach of draining your battery. Maintain these tires pumped up for max battery effectivity.


Air resistance will increase at a fee of velocity cubed. In sensible phrases, which means as you speed up, there’s an exponential rise in resistance. Until you’re on a decent schedule, I might advocate touring at round 15 miles per hour to get one of the best velocity to vary attainable.

Hills and Acceleration

E-bikes used round San Francisco will predictably deplete much more power climbing up hills than an e-bike within the Netherlands. Acceleration, for all intents and functions, places the identical pressure in your battery, utilizing up extra electrical energy and depleting the battery quicker.


It’s logical that the much less time you’ve gotten your battery engaged, the extra vary you’ll get out of it. When commuting, I attempt to use the battery as a “sweat saver”, giving myself a lift solely when the going will get robust. For studios and downhills, I favor to provide the battery a relaxation and do a little bit of the work myself.

Equally, I’ve discovered that batteries actually don’t like standing begins. The excessive present wanted to get your bike going is nicely above what is required to take care of a average velocity, so getting began utilizing your ft will prolong your vary a bit additional.

Caring on your battery

Though batteries are manufactured, they’re affected by bodily circumstances in the identical method that dwelling beings are. They will lose round two to 3 % of their capability per yr in regular circumstances even when unused, and all batteries will ultimately die and be unable to recharge.

Under are a couple of tips about how one can prolong the lifetime of your battery.


You may need heard by means of the grapevine that permitting batteries to make use of up all of their cost prolongs their life over time.

I haven’t learn any dependable sources that affirm this, actually, most advocate maintaining the battery above half cost every time attainable. They work a bit such as you do. In case you expend your whole power and collapse exhausted, your restoration will take a very long time and it’ll have a destructive impact on you over time.

There’s loads of complete materials on the market that teaches you how one can extend lithium-based mostly batteries.


When attainable, batteries ought to be stored at round 60 levels, as that is kind of the optimum temperature for every type of batteries.

Leaving a motorcycle out within the chilly will lower the voltage utilized by your bike which might be observed when driving, so attempt to retailer your bike, or a minimum of the battery, indoors when attainable.


Watch out to make use of the right charging package to juice up your battery. In case you use an inappropriate system or proceed charging as soon as it has already reached full capability, you’ll be able to decrease the quantity of biking fees.


Right here’s some excellent news — lithium batteries are intelligent. It’s unimaginable to overcharge them, whereas nickel-based mostly batteries might be broken if left plugged in too lengthy.

So don’t fear about forgetting to unplug your lithium batteries, they are going to be nice.

E-Bike Battery FAQs

If my battery is at 75% and I cost it as much as 100%, do I lose a charging cycle?

Under no circumstances! You possibly can even enhance the lifetime of a battery by not letting it die.

Attempt maintaining your lithium batteries as near 100% as attainable.

Will my battery be affected by the chilly?

Within the chilly, lithium batteries carry out a lot better than the SLA batteries of previous, however you need to attempt to hold your battery as near 60 levels as attainable to keep away from deterioration.

How do I hold my battery from dying when not in use?

A very good tip is to all the time maintain your battery topped up when not in use. Leaving it to die is detrimental to the battery’s well being, so I might advocate giving it a 30 minute increase about as soon as every week when not in use.

When you gained’t be utilizing a battery for a whole season, similar to winter, it is best to attempt to depart it round about 50%. All batteries discharge over time, so ensuring it’s at 50% for storage will forestall it from discharging utterly.

Can I recycle my battery?

The commonest e-bike batteries, lithium-based mostly batteries, might be recycled in the identical recycling facilities you can take laptop computer batteries to. Most cities have a recycling middle and there’s even a listing of those facilities. Nickel batteries, which aren’t generally used any extra, are a hazardous materials and are very exhausting to recycle.
