8.What care should be taken for TLH E-bike batteries?

Firstly, try to avoid charging up to a hundred %.

Electric bike batteries degrade with the passage of time.

By charging them at high voltages will let them degrade fastly.

Also, charge it fully only when you have the plan to go riding.

It would be best if you charged it to full once in a week so that it can maintain the charge balance of the cells.

This will also result in enhancing the overall capacity of the battery.

Consult your user manual and follow its instructions only.

You should also avoid fully discharging. Charge your battery when it is in between 25-50%.

It would be best if you have weekly and monthly cycles for maintenance for your e-bike.

This won’t exhaust your battery energy.

Always try to match you battery specifications and features with your journey complexities.

If you overuse the battery features, then it could lead to unusual errors.

As an additional note for the colder time of year season, ensure your battery is above freezing before charging, else you could hurt the cells. It is no issue to ride the bicycle in underneath freezing conditions (it doesn’t hurt the battery), simply ensure you let the battery warm-up before charging.

At the point when you are riding in freezing climate, you will see a drop in force and reach; this is typical and anticipated.

You can help stay away from this by bringing the battery inside at whatever point you’re not riding to keep the temperature of the battery up.

That way you will get that additional piece of intensity!

Right maintenance as well as the capacity of your battery as described above will essentially build its life expectancy.

An all-around kept up lithium battery will last around three to five years, though an ineffectively kept up battery can be seriously harmed over only one season or sooner.

9.What factors impact the life of an electric bike battery?

Many factors affect the life of an electric bike battery, but it also depends on how you take care of your battery.

Figure 14 Electric bike

1)Use of right gear at the right time
The most common mistake the electric bike owners make is that they rely on the electric assistance and forget about switching the gears this drains the electric bike battery resulting in a much shorter life.

Expending the right equipment at the correct time saves the battery life significantly.

2)Weight of the rider and extra load
Another dominant factor is the rider’s weight and the extra load the rider is carrying with him.

The more the rider’s weight is, the more energy would be required by the engine from the battery hence leading to excessive draining of the electric bike battery.

3)Terrain conditions
Another factor would be the terrain conditions.

On an elevated or mountainous terrain, the engine would require more power from the battery while on flat terrain the energy expenditure would be relatively less.

4)Frequent stops
Frequent stops and starts demand a lot of energy power so when you are about to start riding you should switch to a lower gear to help your bike to take a start, instead of using the highest assistance level.

This will provide a slow start, but it will significantly impact battery life.

5)Pressure in tires
Keeping your bike’s tire pumped up is another significant thing that most of the bike owners do not give much importance.

Low-pressure tires mean that now the engine has to work much harder, which consequently leads to the significant drainage of the battery.

Hence, to elongate the battery’s life, it is essential to maintain proper pressure of tires.

6)Air dynamics
If you ride your bike in an upright position, it will be hard to accelerate and maintain a high speed this means that you are relying on the assistance to help you gain the rate which will in return drain the battery much faster.

Similarly, if you make a posture that allows you to splash through the wind, then it would require relatively less assistance from the battery.

Batteries do not work well in extreme weather conditions, whether it is too hot or too cold.

You will find that they have the most significant life span in mild weather conditions.

This means that a battery that bears extreme cold of winters will have much less life than the same battery used at a temperature of, e.g. 15°C.

8)Electric bike motor
Type of motor has a significant impact on the battery’s life; more powerful engines demand more energy power from a storm.

10.How would TLH management cooperate with us and what technical help for E-bike we should expect from TLH?

There is a general rule in the electric world, and it applies for Electric bike batteries, too, that is, more voltage is equal to more power.

Manufacturing of Electric bike batteries is usually 24v,36v,48v, but TLH offers batteries in 52v, and 72v batteries.

TLH Electric bike battery manufacturers want to provide an optimum ratio of power and cost, so most commonly, 36-volt batteries are used in electric bikes of 24V.

Most suppliers either offer batteries that range from 24 volts to 48 volts or quote a high price for higher power batteries.

Still, TLH gave you a customized solution at a very economical rate for batteries up to 72 volts.

Usually, batteries more than 48 volts are hazardous for human health, and any means of negligence can cost a life.

TLH provides you with the safest and durable solution with 12 months warranty and lifetime support to ensure your safety.

We are always available to understand your diverse practical needs for electric battery such as cell combination, voltages variation, battery size, cycle life, temperature change, charging, and discharging time.

11.What are the different types of motors in an E-bike?

The two most regular kinds of centre engines utilized in electric bikes are brushed and brushless.
Numerous designs are accessible, fluctuating in expense and unpredictability; direct-drive and outfitted engine units are both utilized.
There are mainly three types of motor locations in an electric bike as described below.
One of them is Front hub, which is located on the front tire, while another location is the rear hub, they provide power from the back to the bike, they provide the more natural effect.
Lastly, mid-drive position, in this location motor is placed in the mid of cycle.
