Product Description
The 3.7V 2000mAh Battery Pack is a complete single-cell assembly, with the wrap, protection and connection considered together. It shares an approximate 19 x 20 x 67mm outline with the 2600mAh option but has a different energy reserve and current rating. The recommended 3.0V discharge cutoff helps the equipment designer set a normal operating endpoint above the lower protection boundary.

Product Details
Electrical Limits
Average current is not enough to choose this pack. A motor start, radio transmission or other short peak may be much higher. Buyers evaluating a 3.7V 2Ah battery pack should compare both readings with the specification before sampling. If the peak stays inside the limit, the design can offer useful capacity without moving to a larger multi-cell pack.
Single Cell Equipment
A 3.7V 2000mAh lithium battery can be evaluated for smart-home controls, pet-care equipment, compact instruments and portable electronics that use a single-cell supply. Confirm the space, load, charging method and connector before treating any application as compatible.
Connector and Lead Details
The connector is often where an otherwise suitable battery fails the fit check. For a 1S1P battery pack, New Journey can match the connector family, pin count, polarity, lead length and wire gauge to the buyer drawing or sample. Label and wrapping can be settled at the same time. Once approved, the sample and specification become the reference for repeat orders.
Cell and Protection Assembly
The 18650 1s1p layout uses one cell in the pack. Confirm the finished dimensions, protection board and lead exit on the approved sample so that the assembly fits the device cavity.
Check the single-cell charging limits
Confirm the charge voltage and termination behavior of the host circuit. Record the selected protection board and connector with the sample, then verify capacity and voltage under the agreed test conditions.

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 the pack fit smart-home or pet-care equipment?
These are application directions for evaluation. Check the device voltage, continuous and peak current, dimensions, connector, polarity and charging method before confirming compatibility.
What charger information is needed for 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.
