3. What Are 52V E-Bike Batteries Made Of?

Like all of the e-bike batteries, our 52V E-bike battery packs are made up of lithium ions or lithium polymer.

52V E-bike batteries are rechargeable batteries made with one of the typical types of Li-ion cells called 18650 cells.

Some manufacturers use lead-acid to make e-bike batteries, but they are not as practical in real life as Li-ion batteries.

Both Li-ion and lead-acid e-bike batteries use cells with their respective electrodes and electrolytes.

Figure 3 Li-ion Cells

Due to the issues regarding weight and the quality of the batteries, lead-acid batteries are less common in most parts of the world.

For example, in Europe, acid-lead e-bike battery manufacturing is only 1%, whereas, Li-ion e-bike batteries represent 99% of the total.

Many e-bike batteries are made from the extensions of lithium ions such as Lithium Polymer (LiPo) and Lithium Manganese (Li-Mn), which create inexpensive but fragile batteries.

We offer customized Li-ion 52V E-bike battery packs in ranging capacities, volts sizes, and shapes that can be built according to your needs.

4. What Are the Maintenance Tips for 52V E-Bike Batteries?

E-bike batteries are a crucial component of electric bikes, that require ultimate care and maintenance for their maximum performance.

Our 52V E-bike batteries are highly durable and can keep running up to ten years in case of regular maintenance and care.

Here are some of the important tips TLH recommends for the 52V E-bike batteries;

To preserve the e-bike battery, it is essential to remove the e-bike battery before cleaning the electric bike; it ensures the battery’s safety.

It is advisable to remove the batteries from the electric bikes when they are not being used, this keeps the batteries secure and in good condition over a more extended period of time.

When storing the 52V E-bike batteries, always place them in a cool or room temperature area, free from moisture.

Storing e-bike batteries in cool places lowers the risk of overheating the cells, which ruins the battery performance.

To keep the batteries safe from dust and moisture and to keep them at a normal temperature, always use battery covers.

We provide waterproof covers and hard shells for this purpose to ensure the protection of the batteries.

Stay aware of the charge time for the battery, overcharging or undercharging the battery affects the lifespan of the battery.

All of our e-bike batteries are Li-ion and they work best when completely charged, however, fully discharging the batteries regularly reduces their ability and performance.

Electric bike batteries are highly flammable and hence, should not be open for seeing the contents and not be put in a heated place.

5. When Should You Discard the Old 52V E-Bike Battery?

There is no one answer to this question, as the lifetime of an electric bike battery varies depending on multiple factors.

The simplest answer is that the lifespan of a battery is determined by its utilization, which indicates when it is time to discard the old battery.

Our 52V E-bike battery gives you 600 charging cycles which is a lot, especially at such high voltage.

In case of increased utilization than the set limit, battery performance will be compromised and it would have to be replaced before 600 charges.

If the battery is not being overused and kept with proper care, you would not have to discard it for almost 2.5 years.

We suggest charging the 52V E-bike battery packs at least once every 30-40 days for our retailers.

6. What Are the Available Upgrades for the 52V E-Bike Batteries?

In terms of upgrades of voltage and amp, 52V E-bike batteries are already an upgraded version of 48V E-bike batteries, with more cells.

Most of the electric bike batteries’ upgrades focus on increasing the voltage of the battery to give it more power and hence better speed of the bike.

There is not much to upgrade in the 52V E-bike battery pack, however, TLH offers an improved version of this which is a 72V E-bike battery solution.

7. What Are the Consequences of Overcharging 52V E-Bike Batteries?

Charging a battery the correct way is a crucial task as it determines the lifespan of an electric bike battery.

For the 52V E-bike battery pack, it is best to consult the user manual provided by TLH, to fully understand the charging requirements.

Overcharging an e-bike battery is never advised, as it can reduce the lifetime of the battery and lead to malfunctioning.

The lifetime of a battery is basically the number of cycles completed before the battery becomes less efficient.

One of the dangerous consequences of overcharging the electric bike battery is overheating, which leads to a couple more problems of its own.

Overheating of an electric bike battery poses the risk of fires or blasts, although it is a rare sight, the chances are still there.

In case of having a fully charged battery in the bike, try to ride it to its maximum limit so that it is not in full charge while out of use.

Fortunately, our e-bike batteries are made with an LED pointer which lets you know the remaining battery percentage so that the chances of overcharging are limited.

Other than that, we make our batteries with smart charging systems that stop the charging when it is fully charged so that there is no fear of overcharging.

8. What Are the Payment Options Offered by The TLH for the Purchase Of 52V E-Bike Batteries?

We accept payments through platforms such as PayPal, Payoneer, Visa, and Union Pay.

We make sure you approve the sample product before moving to the actual production of your order.

Typically, we request 30% of the total payment before starting the battery packs’ mass production.

After the creation has been done, batteries are packed and ready to be shipped, then we ask for the remaining 70% of the payment to be made before actually transporting the order.

For the clients that are looking for payment security, you can make your battery pack requests through our Alibaba store.

9. What Is the MOQ for 52V E-Bike Batteries by TLH?

Prior to the final battery pack request, we offer free sampling to our clients.

We do not believe in setting a specific number for minimum order quantity for 52V E-bike battery packs, however, we prefer clients requesting a handsome number of battery packs.

Our prices are much more reasonable and customer-friendly than the market and we also offer generous discounts to the clients with a huge amount of quantity.

After the mass production, we always offer multiple amendments to the packs until you become satisfied with your final product.

10. How Should You Check the Battery Health of A 52V E-Bike Battery?

Knowing the battery health of an electric bike helps estimate how much life the battery has left.

You can test the battery health of an e-bike battery by checking its current, voltage, and resistance.

For the purpose of measuring all three of these aspects, a multimeter is used.

The multimeter can be connected to the battery and shows measurement options for whichever function you want to check, be it voltage, current, or resistance.

Before starting to measure the battery’s health, make sure that the battery is in complete charge and has been removed from the e-bike.

Multimeter for Ebike batteries

Figure 4 Multimeter for E-bike batteries

Using the multimeter, check that the voltage shown is the same as the voltage mentioned in the battery specifications.

Repeat the same for the other two functions as well and compare them to the user manual of the battery.

The 52V E-bike battery pack most commonly measures a range of 58VDC to 42VDC.

11. Is It Possible to Charge A 52V E-Bike Battery with A 48V Charger?

The answer is no; you can not charge a 52V E-bike battery with a 48V E-bike battery charger.

The 52V E-bike battery is known for its higher voltage which then offers better performance and speed.

The charging voltage is much higher in 52V E-bike battery packs and can not be charged with a lower voltage battery pack.

The 48V E-bike battery charger doesn’t fulfill the charging needs of 52V E-bike batteries because it can only charge up to 70% and then stop due to voltage difference.

12. How Should You Keep the Large Quantities of 52v E-Bike Batteries?

We advise our clients to store their 52V E-bike battery packs in a dry and cool place to keep the batteries from overheating.

The recommended temperature for keeping the e-bike batteries is between 0°C to 10°C; at this temperature, the battery aging process slows down.

Temperatures as low as – 10°C and as high as 60°C can damage the battery and hence should be avoided.

Storing the e-bike batteries with a full charge or full discharge is unwise as it can affect the battery cells.

It is best to keep the battery packs with at least 50% charge, constant humidity levels, and at room temperature.

Studies suggest that the battery decomposition process is the slowest between the charge of 35-75%.

It is because at the charge of 80% or more the chemical activity of electrolytes and electrodes is rapid.

In case of storing the battery packs for a longer period, try discharging them every 2 months.

Before storing the battery packs, separate the terminals of the battery to avoid any short circuit accidents and choose a storing area away from the fire hazards.

For using a battery, stored for a long time, always make sure all of its safety guidelines still apply and the protections are functional.

13. How Often Should You Charge Your 52 V E-Bike Battery? / How Long Does A Single Charge Of 52V E-Bike Batteries Last?

Our technical staff suggests that you should charge the 52V E-bike battery pack after each ride.

We recommend that you should cycle about 24 km to 114 km in a single charge of your 52V E-bike battery.

A typical Li-ion e-bike battery can be charged up to 90% in 2.5 hours and sometimes less depending on the voltage.

We provide 600 charging cycles for our e-bike batteries and recharging at a battery usage of 50% is considered as ½ of a charge cycle.

Keeping your battery fully charged every few weeks is essential, and on average you should recharge the battery packs when they have charged between 30% to 60%.

Never discharge your e-bike battery completely.

14. Are 52V E-Bike Batteries Safe?

52V E-bike batteries are completely safe as we make sure to test them in every aspect before sending them into the market.

We follow a strict quality control process for all of your orders for e-bike batteries.

Our QC staff examines and inspects each and every battery for your order and resolves any issue on the spot.

The technical staff at TLH is experienced at protecting the battery insulation to avoid any mishap from weak layers.

16. What Safety Measures Should be Taken for 52V E-Bike Batteries?

To avoid accidents or mishaps related to our 52V E-bike batteries, we have listed some important safety measures;

In case of inactivity, take the battery down to a minimum of 30% and store it in cool, dry, and constant weather.

After every 30 charges or so, completely discharge the battery so that it can regain its power and act effectively.

Avoid leaving the e-bike battery in a place where the temperature gets too hot or too cold, for it can lead to battery problems and might even cause accidents.

In case of cycling the electric bike at 100%, there will definitely be heat generated from the battery, let it cool down by removing the battery from the bike and pacing it in a cold place.

17. How Are 52V E-Bike Batteries Better Than 48V E-Bike Batteries?

We deal in electric bike batteries with ranging voltages, such as 36V E-bike battery, 48V E-bike battery, 52V E-bike battery, and 72V E-bike battery.

Among them, most common for electric bikes are either a 48V battery or a 52V battery, with each having its own properties.

The major difference between the two battery packs is performance and power.

One of the many reasons a 52V E-bike battery is considered better is because it offers better performance.

The efficiency and the power attained by a 52V E-bike battery is way higher than a 48V E-bike battery due to higher voltage.

The battery life and the charging cycles offered in the 52V E-bike battery are also longer as compared to the 48V E-bike battery.

The 48V E-bike battery suddenly drops in power at half-discharge, whereas the 52V E-bike battery will keep up the same power.

Most of the new models of electric bikes are compatible with 52V E-bike battery packs.

18. How Do the 52V E-Bikes Batteries Perform in Harsh Temperatures?

The electric bike batteries by TLH have ideal performance and activity even after the optimum temperature.

Our lithium-ion batteries are comparatively better at handling extreme temperatures as compared to other batteries.

Even though an electric bike battery is less reactive to extreme temperature, always try to keep and store it at room temperature.

Constantly covering and uncovering the battery packs can decrease the battery’s ability to resist harsh temperatures in the long run.

For understating the battery performance at certain temperatures, you should consult the user manual that comes with the battery pack.

People who live in extreme temperature locations, either too low or too high, need batteries with harsh temperature utilization.

For those, we can design warm and cold covers for the battery packs to normalize the internal temperature.
