- Compact Construction: The 90×43×22mm enclosure supports integration into portable electronic projects.
Electrical Configuration & Output Details
This holder connects two conventional 3.7V nominal 18650 lithium-ion cells in series (2S). In this configuration, the voltage of the two cells is added, while the available capacity in ampere-hours remains approximately equal to that of one cell, assuming matched cells.
- Nominal Output Voltage: Approximately 7.4V with two conventional 3.7V nominal lithium-ion cells.
- Fully Charged Voltage: Approximately 8.4V when both cells are fully charged to 4.2V each.
- Internal Battery Configuration: Series connection (2S).
- Power Control: Integrated ON/OFF switch for manual power switching.
- Output Interface: DC jack connection.
Important: The holder does not regulate or stabilize the battery voltage. The connected device must support the complete battery voltage range, including approximately 8.4V immediately after a full charge. Use a suitable 2S battery protection and charging arrangement where required.
DC Jack & Cable Connection Details
- DC Connector: Integrated DC jack.
- Cable Length: Approximately 12cm according to the supplier’s specification table.
- Wire Termination: Approximately 5mm tinned wire ends, as described by the supplier.
- Connection Method: DC jack interface and pre-attached wire leads.
- Power Switching: Integrated ON/OFF switch.
The DC jack dimensions, polarity, cable wire gauge, wire colour and maximum current rating are not specified. Confirm connector compatibility and electrical polarity before connecting the holder to a device.
Cover, Locking Mechanism & Battery Installation
- Sliding Cover: The removable cover provides access to the two-cell battery compartment.
- Screw-Based Locking: A small locking screw helps secure the cover in place.
- Enclosed Battery Housing: Helps keep the installed cells organized and reduces direct exposure to surrounding objects.
- Convenient Battery Replacement: The removable cover allows access when battery replacement is required.
- Compact Plastic Body: Provides an enclosed structure for portable battery-powered assemblies.
The enclosure has no specified waterproof, dustproof or IP protection rating. It should not be treated as a sealed environmental-protection enclosure.
