DUSLAN 18500 3.7V 1500mAh Lithium-Ion Battery with Tabs

DUSLAN 18500 Lithium-Ion Cell for Custom Packs

This 18500 cylindrical cell delivers 3.7 V nominal voltage and 1500 mAh capacity with tabs on both ends for direct soldering. It suits hobbyists and technicians building or repairing portable power packs, instrumentation or lighting where a slimmer 18.3 mm diameter is required. The lithium-ion chemistry offers high energy density and no memory effect for reliable long-term storage. Users must understand Li-ion charge and discharge limits before assembly.

Replaces Shorter 18650 Cells in Tight Spaces

The 50.3 mm length is slightly shorter than a standard 18650, allowing it to fit compartments that reject the longer cell while keeping the same 18.3 mm diameter. The upgrade is worthwhile when a device or enclosure cannot accommodate the extra millimetres of an 18650 but still needs 1500 mAh capacity and 2.6 A maximum discharge. It is not for applications demanding higher capacity or continuous currents above the rated limit. Buyers needing greater runtime should consider larger formats.

Solder Tabs Directly; Observe Current Limits

Tabs on both ends enable straightforward spot-welding or soldering into series or parallel packs without holders. Installation is simple for anyone experienced with Li-ion safety practices, but exceeding the 1.5 A charge or 2.6 A discharge ratings can cause overheating or venting. Common mistakes include using unprotected chargers, shorting the tabs during assembly, or mixing cells of different age or capacity. The 34 g weight keeps the finished pack light.
