Is this a cell or a complete battery pack?
This product is a single 3.6 V 5700 mAh / 5.7 Ah cylindrical cell. A complete battery pack requires a suitable cell configuration, BMS, enclosure and connections.
What are the nominal voltage and capacity?
The listed nominal voltage is 3.6 V and the capacity is 5700 mAh / 5.7 Ah. Nominal voltage is not the full-charge or discharge cut-off voltage.
What are the cell dimensions?
The listed dimensions are Ø21.15 × 70.80 mm. Confirm dimensional tolerances and allow space for terminals, connections and pack components.
What does the 2.95C discharge rating mean?
The maximum discharge current listed in the supplied inventory is 16.8 A. Dividing this current by the nominal capacity in Ah gives approximately 2.95C. This calculation does not establish a continuous or pulse test condition. Confirm the current limits and test conditions for your pack design; this is not a charging-rate specification.
Can I use this cell in a power-tool or cleaning-equipment battery pack?
Share your system voltage, continuous and peak current, available space and pack requirements so the configuration can be assessed. Matching voltage or physical size alone does not confirm compatibility.
What are the delivery time and return terms?
Delivery Time: 30–60 Days. Warranty & Support: 30 days free return. Confirm delivery arrangements and the return process when requesting a quote.
How can I get a price?
