NEW JOURNEY
Product Description
The 7.4V 2000mAh Battery Pack offers a modest energy reserve in a two-cell 18650 layout. Its dimensions are close to the 2600mAh model, but capacity and current ratings should not be transferred between them. Device standby consumption can be important when operating periods are long. Charger settings follow the 8.4V upper endpoint and the approved current for this assembly.

Product Details
Two Cell Construction
Two 18650 cells are connected in series, with no parallel group. That is the confirmed 2S1P structure: voltage rises to the required level while pack capacity remains 2000mAh. The 2S1P 18650 battery pack uses heat-shrink film rather than a rigid molded housing. That saves space, but it also makes the buyer tolerance, wire-exit and insulation-clearance drawing important before enclosure release.
Keep protection inside the fit review
Verify that the housing does not press on the wrapped cells or cable exit. Record the agreed charging profile and low-voltage behavior with the sample so later replacements use the same electrical basis.

FAQ
What configuration and chemistry are confirmed?
The product uses NCM 18650 cells in a confirmed 2S1P arrangement.
Which BMS protection functions are confirmed?
The reference specification confirms a 6A BMS. Individual protection functions should be agreed against the approved BMS specification for the order.
What charging voltage and current are specified for this model?
Charging Cut-off Voltage: 8.4V maximum; Maximum Charge Current: 2A; 0.5C charging 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.
How much installation space should I allow for this battery?
Dimensions: Approx. 38 x 20 x 68mm; Weight: Approx. 0.12kg. Allow access to the terminals or connector and room for the cable bend and retention hardware. Compare the finished assembly drawing with the actual equipment space before fixing the mounting points.
