1.What is a 24v lithium ion battery?

A lithium-ion battery is a form of rechargeable battery in which lithium ions circulate within cathode positive and anode negative electrodes to charge and discharge the battery. Rechargeable batteries are referred to as secondary batteries, whereas non-rechargeable batteries are referred to as primary batteries

Because lithium-ion batteries can store large amounts of electricity, they are utilized in a variety of applications, including consumer devices for example cellphones, computers, industrial purposes and cars.

The symbol 24 V indicates that the battery provides 24 volts when subjected to a nominal load. The same logic applies to a 48V battery bank, which delivers 48 volts, and so on.

A 24V battery is one technique to construct a 24V system. 24V batteries are less in demand and more difficult to get than 12V batteries. 24V batteries are also expensive than others. They do, however, take up less space than connecting additional batteries in series. If space is an issue, a single 24V battery may be a preferable option.

2.What are the different usages of 24v lithium battery?

Lithium-ion batteries have revolutionized the battery industry. They are used in many daily used things. Some of them are discussed below. 

24v trolling motor battery

These 24V trolling motor batteries provide several benefits over lead-acid batteries for example, a sleek design, they are lighter than lead-acid batteries, have a high number of charging/discharging cycles, have a very less self-discharge rate, have a more consistent output voltage and have practically no capacity damage as the current increases, etc. 

Furthermore, lithium trolling batteries also have certain drawbacks, such as a high initial cost and safety problems. To ensure safety, lithium trolling motor batteries are completely Lithium Iron Phosphate (LiFePO4) batteries with built-in Battery Management Systems (BMS), which safeguard the battery from undesirable occurrences such as short circuits and other types of overcharging and over-discharge.

The greater power requirements and extended wire lengths of bigger trucks and buses necessitate the usage of 24V battery systems in these vehicles. Larger boats and RVs with complex solar systems also use 24V. For fishing boats, a 24V system is commonly used to power trolling motors

24v e-bike battery

The use of 24v e-bike battery connections in the batteries and adapters supplied in the sets ensures that they are compatible with a broad range of electric bike manufacturers.

This makes the battery perfect for either replacing a worn-out battery or starting from fresh when creating an E-BIKE.

·Performance and reliability

With the help of advanced control electronics, the battery and the electric motor controller can work in perfect harmony, delivering the correct immediate power and the highest continuous rating - maximum performance without compromise.

There is also an electrical BMS built into the battery to keep it from being destroyed, deeply drained or overloaded if it is charged too long.

24v truck battery

For electric, hybrid, and plug-in hybrid trucks, the automotive industry is generating a requisite for Li-ion batteries. These batteries have a high charging capacity and a long lifespan due to their ability to store huge quantities of energy and to be recharged numerous times.

24v lithium marine battery

A new type of battery is emerging for marine vehicles such as labor or tug boats as well as a recreational craft like speedboats and yachts. A boat's appliances may be powered while docked using Li-ion batteries, which are discreet and competent.

24v scooter battery

Users of wheelchairs, motorcycles, scooters and other agility devices rely on lithium-ion batteries. Lithium-ion batteries, unlike cadmium and lead batteries, do not contain any compounds that might affect a person's well-being.

3.What are the weights of the different available Lithium ion batteries?

Because batteries come in a variety of forms and sizes, it's difficult to offer a definitive response to this question. As recently as 2014, Panasonic developed the world's smallest lithium-ion battery, with a diameter of 3.5 millimeters; it is only 0.6 grams in weight.

The weight of these batteries is always a problem because technology is meant to be cost-effective, especially for huge power products like televisions. The fact that lithium is the lightest metal and has the largest electrochemical potential is fortunate for us. Since Lithium has the highest specific energy per weight, a tiny amount of it will perform the job.

Nevertheless, the whole-cell pack and battery aren't only made of Lithium. Weight gains are caused by several additional factors. The weight of a lithium-ion battery may be determined by comparing it to the weight of a certain kit that it can power.

One of the significant advantages of lithium is weight savings. A 105 Ah lithium battery will weigh around 28KG, whilst a 60Ah lithium battery will weigh around 7.7KG, even though both have relatively comparable usable capacity. A 165Ah Lithium battery, on the other hand, will weigh 53.6 KG, but a 100Ah Lithium battery with greater usable power will weigh 12.8 KG.

Different types of lithium batteries weigh differently, for understanding some of them are discussed below keeping 20kWh constant: 

• A 20kWh Lithium Cobalt Oxide type lithium-ion battery will weigh between 100 and 133.33 kg.
• The weight of a 20kWh Lithium Manganese Oxide type li-ion battery will vary from 133.33kg to 200kg.
• As an example, for every 20kWh of a lithium-ion battery, the weight will range from 90.9kg to 133.3kg.
• There are two weight ranges for 20kWh of Lithium Iron Phosphate type Lithium-Ion battery: 166.66kg and 220.22.
• 76.92kg to 100kg is the weight of a 20kWh Lithium Nickel Cobalt Aluminum Oxide (Li-ion) battery when fully charged.
• If you have a 20kWh Lithium Titanate type battery, it will weigh between 250 and 400 pounds.

4.How do you differentiate 24v 100ah lithium ion battery, 24v 200ah lithium battery and 24v 400ah lithium battery?

Different lithium batteries have different functions; 24V batteries come in different types of voltages and meet the needs of the products it is used in. But this doesn't always suggest that the 24V battery is superior. Various devices require a specific voltage to function. Trying to run a 12V gadget off a 24V battery is likely to cause damage to the equipment. This means that they cannot be used interchangeably.

24v 100ah lithium-ion battery produces 2400Wh and 2.4 kWh of energy when fully charged. The calculation is below.

The battery contains 24V∗100Ah=2400Wh

24V∗100Ah=2400Wh=2.4kWh of energy when fully charged. 

24v 200ah lithium-ion battery produces 4800Wh and 4.8 kWh of energy when fully charged. The calculation is below.

The battery contains 24V∗200Ah=4800Wh

24V∗200Ah=2400Wh=4.8kWh of energy when fully charged.

24v 400ah lithium-ion battery produces 9600Wh and 9.6 kWh of energy when fully charged. The calculation is below.

The battery contains 24V∗400Ah=9600Wh

24V∗400Ah9600Wh=9.6kWh of energy when fully charged.

5.Do we use 24v lithium ion battery in the electric bike?

As a result of their high energy density and improved power per mass, 24 V Lithium-ion batteries are now the most widely utilized technology in electric bikes. This has allowed the creation of various types of batteries with decreased weight and dimensions at reasonable prices.

High-capacity and long-lasting 24 V Lithium-ion batteries form the battery's core. Your electric motor will run longer on a single charge, and you'll have an efficient source of energy that can offer both temporary and continuous power.

Encased not just high-quality cells, but also an advanced battery management system (BMS) that continually checks the battery's operational conditions, in a robust, sealed container.

This provides dependability when driving and safety while charging by protecting in contradiction of deep discharge, overcharging, and overheating.

6.Compare and contrast 24v 10ah lithium ion battery and 24v 20ah lithium ion battery?

Volts and amp-hours are the two measurements of a battery (AH). One-thousandths of an amp-hour is called milliamp-hours (mAh) (for example, a 4.6Ah battery is equal to 4600mAh). Ah hours are a measurement of how much energy a battery can hold. Standardly the mAh rating also indicates how long a battery will survive.

It is, nevertheless, essential that the voltage ratings are kept within an acceptable limit. Such as 3.6v, but you acquire one with 3.7v. It's still okay. As a general rule of thumb, never exceed one volt above your initial rating when dealing with voltage. When replacing an original battery with a new one, you may only use a replacement battery that is up to 4.6v.

To further understand the main difference between the two calculations is done below. 

24v 10ah lithium-ion battery produces 240Wh and 0.24 kWh of energy when fully charged. The calculation is below.

The battery contains 24V∗10Ah=240Wh

24V∗10Ah=240Wh=0.24 kWh of energy when fully charged. 

24v 20ah lithium-ion battery produces 480Wh and 0.48 kWh of energy when fully charged. The calculation is below.

The battery contains 24V∗20Ah=480Wh

24V∗20Ah=240Wh=0.48kWh of energy when fully charged.

7.Is 24v is a deep cycle battery?

There is a finite lifespan for rechargeable Lithium-Ion batteries, and they will gradually lose their ability to retain a charge as time goes on. Aging is an irreversible process. As the battery's capacity diminishes so does the product's run time.

Once a 24V lithium-ion battery is not in use or storage, it continues to slowly drain (self-discharge). Battery charge status should be checked regularly. Information on how to check the battery's state, as well as battery charging instructions, are usually included in the product's user handbook.

All lithium-ion cells are "deep cycle," which means they can be completely charged and drained several times without losing their capacity. Limiting each discharge to 80 percent of the battery's rated capacity will extend the battery's life.

8.Is 24v is a rechargeable battery pack?

24V lithium-ion batteries should not be left uncharged or fully charged for extended periods of time. It has been established that 40 to 50 percent capacity and low temperatures, which should not go below 0°C, are the best storage conditions. Storage at 5°C to 10°C is recommended. Self-discharge means that a recharge is required every 1 year at the absolute least.

Temperature affects the self-discharge of lithium-ion batteries, which can range from 3% to 5% each month.

Rechargeable 24V Lithium-Ion Batteries can be used up to 1000 times. This is only possible under ideal conditions. The number of cycles might reduce depending on how the batteries are used and cared for. The capacity of a product declines with time. Batteries are said to be exhausted when they are less than 70% of their original capacity.

9.Can we use 24 volt lithium ion battery for solar?

Yes, we can use 24V lithium-ion battery for solar purposes because solar panel comes in different ranges of watts and volts

It's not just a matter of following the rule of thumb. They are distinguished based on five factors:

• Compatibility with Battery

• Compatibility with Inverter

• Compatibility with Charge Controller

• Real Use Case (Applications)

• Range & Pricing

1. Compatibility with Battery

The rating of a solar panel is determined by the rating of the battery used to power it. On the whole, you'll want to link your solar panel's voltage with that of your battery's voltage. One thing to keep in mind is that it is difficult to find a 24V battery on the market, but you may make one by connecting two 12V batteries in series. 

24V panel - 24V (2* 12V batteries in series connection)

2. Compatibility with Inverter

Solar panels, like batteries, should be attuned to the inverter's grade. A 12V solar panel, for example, should be connected to a 12V inverter, whereas a 24V solar panel should be connected to a 24V inverter. Inverters come in a variety of voltage ratings, including 12V, 24V, and 48V.

24V battery (connected in series) - 24V inverter - 24V solar panel will be connected

3. Compatibility with Charge Controller

Inverter and battery wattage values should match a charge controller's wattage rating. Use a 12V Charge Controller if you have a 12V battery and an inverter. In the same way, 24V. Keep in mind that the rating of the solar panels should not be higher than that of the charge controllers in this situation. So a 9 Ampere solar panel cannot be connected with an 8 Ampere charge controller, and vice versa. 

4. Real Use Case (Applications) 

Large houses, hospitals, banks, and businesses, as well as off-grid applications like industries, flats, parking lots, parks, and government buildings, may all benefit from the usage of a 24V solar panel for a variety of purposes.

5. Range & Pricing

Always keep in mind the prices of different batteries and their solar panels. 24V is expensive than 12V but it is efficient and takes less place.

10.Is 24v lithium battery is a series or parallel battery?

24V lithium battery can perform on both series and parallel connections. Battery banks can be increased in capacity by connecting many batteries in parallel. Here, the positive and negative battery connections are linked until you achieve your desired capacity. Using a series connection, you may raise the voltage of the battery system by connecting two or more batteries. The negative and positive of one battery are linked until the necessary voltage has been reached. The battery system will be 24V if connect two 12V batteries are in series, for example. 

Series connection

To raise the voltage of the battery system while maintaining the same amp-hour rating, two or more batteries can be connected in series. Each battery needs to have the same voltage and capacity rating when connected in series, or else the battery will be damaged.

The positive and negative terminals of one battery are connected in series to produce the required voltage. Use a charger that matches the system voltage while charging several batteries in series, otherwise, you will damage the batteries. A multi-bank charger is recommended to avoid an imbalance between batteries.

Parallel connection

Using parallel connections, you may enhance the amp-hour capacity of your battery bank while maintaining the same voltage. Connecting the positive terminals of batteries with a cable, then connecting the negative terminals with a second cable, will result in your desired capacity.

A parallel connection is not intended to allow your batteries to power anything over their usual voltage output, but rather to extend the time that they can power devices. It is crucial to remember that while charging parallel-connected batteries, the greater amp-hour capacity may necessitate a longer charge time.     

11.Is it OK to just replace my existing (lead-acid) leisure battery with a lithium battery?

It is not recommended. However, as long as the lithium-ion battery is from a trustworthy provider, it's typically safe to do so, and you'll instantly benefit from some of the advantages that lithium batteries have to offer. The battery, on the other hand, is unlikely to be charged to its maximum capacity or particularly effective in the first place.

Even though a lithium battery may be charged at over 60 Amps, without changing the wiring of a car, the alternator's charge rate may be nowhere near that amount of power.

It's also possible to shorten the usable life of a lithium battery if it's charged with a mains charger or solar regulator built for lead-acid batteries. It strongly advocated, installing a lithium battery with suitable charging methods and cable for these reasons.

12.How does a 24v lithium battery affected by temperature?

In a conductive route, the current flowing through the battery is generating heat. A variety of thermal management methods are used to regulate the heat created during charge/discharge operations, such as cooling systems or heat evacuation through exterior battery casings.

A battery's temperature decreases with time in an environment where heat may be removed. It is also possible for new processes to occur when heat cannot be removed from the battery. This results in a rise in battery temperature. What we call this mechanism as Thermal Runaway.

Thermal runaway happens when a cell's temperature rises uncontrollably, causing it to fail prematurely. A certain temperature is reached, at which time the electrolyte evaporates, generating gases that must be vented when the cell's pressure climbs over a pre-determined threshold. This temperature increase can be caused by a variety of factors, including, but not restricted to:

• Cells used in high-temperature environments;

• An internal short circuit caused by a cell fault might cause the cell to overheat.

An increase in the charge or discharge current. Heat is created when cells are charged or discharged, heat production increases with the current;

• Battery tab with an incorrect electrical connection causes a rise in electrical resistance, which creates heat at the electrical contacts

• Internal shorts and heat production might occur as a result of mechanical damage to the battery.

If one cell component fails due to thermal runaway, the fire may spread to nearby cells. As each cell is used, a pack can be destroyed in a matter of seconds or over the course of several hours. There should be separators between the cells to prevent the failure of one cell from spreading to the others in the pack.

If one cell component fails due to thermal runaway, the fire may spread to nearby cells. As each cell is used, a pack can be destroyed in a matter of seconds or over the course of several hours. There should be separators between the cells to prevent the failure of one cell from spreading to the others in the pack.

The following are probable outcomes of thermal run-away:

I. Gas emission 

II. Fire 

III. Explosion
