DUSLAN 6-Pack 18500 Lithium-Ion Standard Battery 3.7V 1400mAh Tabs

Pack of six 18500 lithium-ion cells

These six 18500 lithium-ion cells deliver 3.7 V nominal voltage and 1400 mAh capacity each. They are aimed at hobbyists and engineers building custom battery packs for portable electronics, instrumentation or RC projects. The tabbed terminals on both ends simplify series or parallel soldering without spot-welding equipment. Buyers should be comfortable with lithium-ion safety practices before use.

Check voltage, current limits and physical fit

Verify that your charger and protection circuit support a maximum charge current of 1.5 A and a maximum discharge current of 2.6 A per cell. Confirm the device cavity accepts the 50.3 mm length and 18.3 mm diameter, noting the 18500 cell is a little shorter than the 18650 cell. Ensure your pack design accounts for the 34 g weight per cell and includes proper insulation for the exposed tabs.

Tabbed cylindrical cells with safety warnings

Each cell weighs 34 g (1.2 oz) and uses a cylindrical lithium-ion chemistry with no memory effect and long storage life. Tabs on both ends allow direct soldering but leave conductors exposed, so insulation and strain relief are essential in daily handling. The supplier warns that lithium-ion batteries may explode if charged or discharged improperly and disclaims responsibility for misuse.
