NEW JOURNEY
Product Description
The 3.7V 2600mAh Battery Pack uses one 18650 cell with protection and external leads. Its approximate 19 x 20 x 67mm assembly is larger than a bare cell outline, which matters in a close-fitting holder. The device charging circuit must use the 4.2V maximum endpoint. Protection current, connector capability and enclosure temperature all remain part of the installed load assessment.

Product Details
Device Requirements
A 3.7V 2600mAh lithium battery can be evaluated for single-cell equipment such as compact instruments or portable electronics. Confirm operating voltage, load, required runtime, cavity, connector polarity and charger compatibility on the actual device.
Identify the supplied assembly boundary
The approved order should state whether protection, leads and connector are included. Keep polarity and the allowed current tied to that finished assembly rather than treating a nominal cell capacity as a complete battery specification.

FAQ
How many cells are in each pack?
Each finished pack uses one 18650 cell in a 1S1P configuration. Multiple units shown together do not form one multi-cell pack.
Does a cell certificate cover every finished pack?
No. Check the certificate validity, cell or pack model scope and applicability to the exact ordered configuration.
Can I reuse a charger with this battery?
Charge cut-off voltage: 4.2V maximum; Maximum charge current: 2A; 0.5C recommended. Match the charger profile, polarity and connection to the ordered assembly. A voltage-class label alone does not establish compatibility with an existing charger.
What does the listed weight tell me about installation?
Approximate weight: 0.06kg. Weight alone does not define the battery envelope or mounting points. Obtain the external dimensions and retention drawing for the selected build before fixing the device enclosure. Include the terminal position and access needed to secure the battery.
