Depending on the required voltage and runtime, multiple INR18650 cells can be connected in series or parallel to create a battery pack that matches the device’s electrical requirements.
04. Why Choose INR18650 Batteries for Consumer Electronics?
The INR18650 format offers several practical characteristics that make it attractive for electronic product development.
Standardized Cylindrical Design
With a nominal diameter of approximately 18mm and a length of 65mm, the 18650 format is widely recognized in the lithium-ion battery industry. Its standardized dimensions make it easier for manufacturers to incorporate cylindrical cells into suitable product housings and battery pack designs.
Flexible Battery Pack Configurations
INR18650 cells can be assembled in different series and parallel configurations to achieve the required voltage and capacity.
- 1S1P: 3.7V nominal voltage, 2600mAh capacity.
- 2S2P: 7.4V nominal voltage, 5200mAh capacity.
This flexibility allows manufacturers to select battery configurations according to their product’s electrical specifications.
Balanced Energy and Power Performance
INR lithium-ion chemistry is commonly selected for applications requiring a balance between energy capacity and discharge performance. However, actual performance depends on the specific cell design and manufacturer specifications. Capacity, discharge rate, internal resistance, and operating temperature should all be evaluated during battery selection.
05. PKNERGY INR18650 Battery Solutions
PKNERGY provides INR18650 cylindrical lithium-ion battery solutions for consumer electronics manufacturers, with different configurations designed to meet varying voltage, capacity, and installation requirements.
Two available options include a compact 3.7V single-cell configuration and a higher-capacity 7.4V 2S2P battery pack.
3.7V 2600mAh INR18650 Battery – 1S1P
Designed for electronic products requiring a compact 3.7V rechargeable power source, this configuration uses a single INR18650 cell.
| Battery Type | INR18650 |
| Configuration | 1S1P |
| Nominal Voltage | 3.7V |
| Rated Capacity | 2600mAh |
| Discharge Rate | 1.5C |
| Charging Temperature | 0°C to 45°C |
| Discharging Temperature | -20°C to 60°C |

With four INR18650 cells connected in a 2S2P configuration, this battery pack provides twice the nominal voltage and capacity of the single-cell option. It can be considered for electronic devices requiring a 7.4V rechargeable battery supply and higher energy capacity.
06. Choosing the Right INR18650 Battery for Your Product
Not every electronic device has the same battery requirements. Before selecting an INR18650 cell or battery pack, manufacturers should evaluate several important factors:
- Voltage: Does the device require a 3.7V or 7.4V power supply?
- Capacity: How much energy is needed to support the expected operating time?
- Discharge Current: Can the battery support the device’s continuous and peak current requirements?
- Dimensions: Does the battery fit the available installation space?
- Operating Conditions: Can the battery operate within the product’s expected temperature range?
A suitable battery solution should match the complete electrical and mechanical requirements of the final product.
