NEW JOURNEY
Product Description
The 7.4V 5000mAh Battery Pack cannot be specified completely by voltage and capacity alone. The 18650 version is approximately 38 x 38 x 67mm and 200g, while the 21700 version is approximately 45 x 22 x 72mm and 180g. These alternatives suit different cavities. The selected cell platform should remain fixed in repeat orders alongside the connector and lead route.

Product Details
Portable Instrument Evaluation
A portable instrument lithium battery needs to fit both the instrument cavity and its electrical demand. Review normal and peak current, connector polarity, cable routing and the charging method. For equipment with additional regulatory requirements, confirm the evidence needed for that device and the ordered battery configuration.
Charger and Cutoff
This is a 2S pack, so the charger must suit the stated 8.4V upper limit. Keep the charging current within the stated 2A maximum. A 7.4V NCM battery pack also needs the equipment and charger to agree on low-voltage behavior. Confirming those limits early is a small step that prevents many sample-stage problems.
Approve one cell-layout drawing
Identify the selected option by cell format, dimensions and mass. Keep its cable and protection details together; mixing the dimensions of one version with the weight of the other would invalidate the receiving check.

FAQ
What charger is required?
Use a charger suitable for a 2S NCM pack and the limits in the approved specification. The listed maximum charge current is 2A.
Do both 5000mAh layouts use the same installation space?
No. The 18650 2S2P reference is approximately 38 × 38 × 67mm and 0.20kg; the 21700 2S1P version is approximately 45 × 22 × 72mm and 0.18kg. Select the layout before fixing the device enclosure and allow additional space for the leads and connector.
Are JST and DC5521 interchangeable ordering options?
They are alternatives, not interchangeable connections. Specify the exact JST housing or DC5521 pin polarity, lead routing and load requirement in the order drawing. A connector option does not inherit the pack’s full current rating automatically.
What discharge limit should the equipment designer use?
Maximum Continuous Discharge: 15A; 15A BMS rating. Retain the stated conditions when checking the operating load, connector and wiring.
