Lithium batteries have become a popular choice for many applications, including scooters, bikes, portable electronics, and solar systems. These batteries come under modern battery technologies. However, one of the common varieties is a 36 volt lithium battery.
When choosing a 36-volt lithium battery, you must consider the weight of the battery, but how much does it weigh? In this blog article, let’s explore what are the factors that influence the weight of these batteries and how much they cost.
What is 36 Volt Lithium Battery? Basics
Before getting into the specifics regarding weight, a little education on lithium batteries is helpful. Lithium batteries have high energy density—in other words, a lot of energy is available in a relatively small- battery.
Moreover, they have a lightweight package when compared to the old-style lead-acid batteries. This trait makes them very desirable in circumstances where weight is an overriding factor.
The application of lithium batteries is wide in many applications; however, different weight issues relating to its capacity in amp-hours or Ah, type of lithium chemistry used, and even design of the battery pack do vary.
Weight Variation Factors in a Lithium Battery
1. Capacity (Ah):
Capacity is one of the main determinants of weight in any battery. In most instances, capacity refers to a quantity of current that a battery can supply within a period of time and is measured in amp-hours.
High-capacity batteries store higher amounts of reserve energy and, as such, are heavier. For example, a 36-volt, 10 Ah capacity battery will be heavier than a similar 36-volt, 5 Ah capacity battery.
2. Chemistry:
Another influencing factor concerning weight is the type of lithium chemistry. The common chemistries of lithium are lithium iron phosphate (LiFePO4), lithium cobalt oxide (LiCoO2), and lithium nickel manganese cobalt oxide (NMC).
All these chemicals have different energy densities, hence weights. A typical example is that LiFePO4 batteries, while noted for their long cycle life, batteries explode and safety, may be heavier than other lithium chemistries of similar capacities.
3. Design and Build:
Others are the type and thickness of the casing, the number of cells deployed in the pack, inbuilt features like the BMS, or any cooling mechanisms that will still further add mass to the batteries.
The design and construction of the battery pack further contribute to determining the weight of the batteries.
4. Cell Format:
Li-ion batteries are available in many different cell formats. To name a few, there are a host of various cylindrical cells, a number of different types of prismatic cells, and pouch cells.
Form can have an impact on the overall weight of the battery pack since cylindrical cells can be utilized in configurations that enable a more compact and possibly lighter battery compared to what is achievable with the prismatic cells.
Weight Range Average
This would be an approximation for giving one an idea, but a normal 36 volt lithium battery could weigh from 2.5 kg to 6 kg or 5.5 pounds to 13.2 pounds. Of course, this may be altogether different based on but not limited to the following:
Smaller Capacity Batteries: Those such as 5Ah can normally stay at the low end of the scale between 2.5 kg and 4 kg, distinguishing between 5.5 and 8.8 lbs.
Larger Capacity Batteries: e.g., 10 Ah or greater Weight increases proportionally speaking with the capacity. On the other hand, larger capacity batteries are seen weighing from 4 kg to 6 kg (8.8 lbs to 13.2 lbs) and even more in some cases.
Application-Specific Considerations
Electric Bikes and Scooters:
The most common batteries used for electric bikes and scooters are 36 volts, and their usual weight ranges between 2.5 kg and 4.5 kg. It would more correctly depend on the capacity and design of a battery.
Solar Power Systems:
Energy storage in solar power applications is possible with 36-volt lithium batteries. Such batteries may be a bit heavier due to added safety features and greater capacities, but weigh in within the range of 4 kg to 6 kg (8.8 lbs to 13.2 lbs).
Portable Electronics
In portable electronic equipment, the weight of a 36 volt lithium battery isn’t that important but is typically within the lighter range.
Why Does Battery Weight Matter?
The weight of a system can sometimes be a critical consideration in many applications. For example, if a lighter battery is used in electric vehicles, this will result in higher performance coupled with greater overall efficiency.
In stationary applications, such as storing energy from solar panels, the weight is less of an issue as compared to energy capacity and overall durability.
Future Trends
Improvement of technology is a never-ending process, and thus the work of lightweight lithium batteries and efficiency improvement keeps continuing by all over the china Ebike lithium battery supplier and manufacturer companies.
Material development, cell level, and battery management system advancements may facilitate the reduction of batteries to lighter weights in the coming times without compromising either performance or safety.
Conclusion:
Concluding it in simple words, the weight of a lithium 36-volt battery would depend upon the specified capacity for the battery, its chemistry, cell design, and format. You can generally expect it to be within the range of 2.5 to 6 kg, or approximately 5.5 to 13.2 pounds.
Knowledge of these factors basically helps in picking the right battery to balance weight against performance and capacity requirements.
