E BIKE BATTERY

The battery is one of the most important parts of any E-BIKE, as well as the most expensive. The battery is the deciding factor in how long the vehicle can be used without recharging, how long it will work how much it weighs etc. In general, when you choose an elec-tric vehicle, the battery is the component that you must pay the most attention to.
They can be used for a longer time period as compared to the lead-acid battery packs & also take care of the environment, being non-polluting.
DUAK is serving with quality & proving to be a one-stop solution for all your electric vehicle battery requirements.
In terms of electric vehicle, Lithium batteries usually have following volts in sequences
(48.1V, 51.8V, 59.2V, 74V, in Lithium NCM chemistry)

48V, 51.2V 60.8V 64V 70.4V in Lithium LFP chemistry)

 

In Indian market we have two types of lithium rechargeable batteries. Because of their varied chemical compounds, they perform differently. When safety became a concern in the industry, many manufacturers switched to lithium iron phosphate. This increased safety, cycle life, and shelf life, but reduced capacity. Many manufacturers tailor their chemical compounds based on device use. Searched a good battery Pack is nearly going impossible in market because the market is full of suppliers who are offering the clone lithium batteries under the names of famous brands. Those batteries are rated the same as standard lithium batteries yet no one guaranty about their lifespan and also their performance is not as good as you expect. To overcome this case and provide our customer best possible Lithium battery we have in-house cell testing lab with different kind of machine so that we can provide you best quality of battery with original cell to our valuable customers. We offer good lithium battery packs with the best quality at a reasonable price to or customers. We provide you the value for what you are paying

DUAK helping here to understand which battery good for your vehicle

Selecting a good battery directly determines its efficiency and the distance you can travel on a single charge. Even with the same size and weight, different batteries can work quite differently depending on the type and structure. All batteries have characteristics including Voltage, Capacity, Life Cycle, Charging time and total battery size, weight.

Voltage

In terms of electric vehicle, “Lithium batteries usually have volts in sequences of (48.1V, 51.8V, 59.2V, 74V, in Lithium NCM chemistry) and (48V, 51.2V 60.8V 64V 70.4V in Lithium LFP chemistry)”
Geurts said adding, “volts pretty much mean power — how powerful a battery can be, but it also lends to top speed.” Given what you now know about volts, you should understand why it can become very important to look at the number of volts in an electric bike battery relative to the bicycle’s entire configuration. You want the battery and motor to work together to get the desired performance.
Sometimes called nominal voltage. Voltage is measured in volts (V) which is used to describe how fast electrons move. More voltage = more speed!
Volts are a measurement of tension. How much pressure can be contained in the battery?
“A 48V battery will not likely propel an electric bike 50 miles per hour because it simply doesn’t have enough pressure to rotate a wheel that many revolutions. If you climb up steep hills, a 48V battery will outperform a 36V because the 36 [volt] system will be working harder to produce the same results,” Geurts said.
It is possible to have too many volts. “If you have a 72V battery that is only propelling a system at 20 miles per hour then that means that you have unused voltage or really underutilized voltage in that system,” Geurts said.
Most e-bike kits are rated for a specific voltage range. A typical 48V e-bike needs a battery that delivers power between 42V and 54V. A 48V pack at 54V is 100% charged and holds as much energy as it can; at 42V it should shut down and stop giving power before causing permanent damage. More on the BMS (Battery Monitoring System) in a bit. The common number ’48V’ is the average operating voltage.

Capacity

Capacity is the amount of energy that can be stored in the battery. It is the main characteristic of any battery. The unit of measurement is the ampere-hour (Ah). Battery capacity (AH) is defined as a product of the current that is drawn from the battery while the battery is able to supply the load until its voltage is dropped to lower than a certain value for each cell.
Battery capacity is measured in amps × hours (AH). For example, if a battery has 25AH capacity and provides 25 A average current to a load, in theory, the battery will last 1 hours. In reality, however, the way the battery is discharged has an impact on the actual battery life. Discharging a battery at the manufacturer-recommended rate normally helps the battery deliver close to its nominal capacity.

Cycles

Cycle life is the number of complete charge/discharge cycles that the battery is able to support before that its capacity falls under 80% of its original capacity. … According to your link the Li Po batteries generally can support 600 full charge/recharge cycles before its capacity falls under 85-80%.
The actual battery life is determined by the number of cycles and it depends on the operating conditions of the battery. The longer the battery is discharged, the fewer possible cycles can be expected from it.
When you discharge a battery (use it to power your appliances), then charge it back up with your panels, that is referred to as one charge cycle. We measure the lifespan of batteries not in terms of years, but rather how many cycles they can handle before they expire.
Think of it like putting mileage on a car. When you evaluate the condition of a used car, mileage matters a lot more than the year it was produced.
Cycle life is also a function of depth of discharge (how much capacity you use before recharging a battery). Deeper discharges put more stress on the battery, which shortens its cycle life.

Charging time

With higher efficiency also comes a faster rate of charge for lithium batteries. They can handle higher amperage from the charger, which means they can be refilled much faster than lead-acid.
We express charge rate as a fraction, such as C/5, where C = the capacity of the battery in amp hours (Ah). So a 430 Ah battery charging at a rate of C/5 would receive 86 charging amps (430/5).
Lead-acid batteries are limited in how much charge current they can handle, mainly because they will overheat if you charge them too quickly. In addition, the charge rate gets significantly slower as you approach full capacity.
Lead acid batteries can charge around C/5 during the bulk phase (up to 85% capacity). After that, the battery charger automatically slows down to top off the batteries. This means lead acid batteries take longer to charge, in some cases more than 2x as long as a Lithium alternative.
